Currently, cyclotron magnetic field measurement systems are used for magnetic field correction of a superconducting cyclotron and a superconducting cyclotron, and are used for improving the position and accuracy of a measurement magnetic field.

This magnetic field measuring apparatus measures the magnetic field inside the cyclotron using a Hall sensor. The hall sensor is placed inside the cyclotron, and the Hall sensor is moved by driving the step motor to measure the entire magnetic field inside the cyclotron.

The step motor for moving the hall sensor is mounted outside the cyclotron, and measures the position and movement distance of the hall sensor moved using the encoder.

Therefore, the cyclotron can not be made compact, thereby causing a leakage magnetic field and causing an error due to the extension of the drive shaft . In particular, in the case of a superconducting electromagnet as well as a superconducting magnet, there is a problem that an error due to the influence of a magnetic field of the motor due to a high magnetic field,

FIG. 4 is a sectional view of the first moving member 110, the second moving member 120, the guide rail 130 The sensor carrier 140, and the sensor 150 are extracted and shown.

The first moving member 110 and the second moving member 120 according to the first embodiment of the present invention are disposed so as to be spaced apart from each other. The first shifting member 110 is disposed on the outer surface of the first heel 21a and the second shifting member 120 is disposed on the outer surface of the second heel 21b facing the first heel 21a, The distance between the first moving member 110 and the second moving member 120 may be at least the diameter of the sector portion 21. And may be formed to be slightly larger than the diameter of the sector portion 21. Here, the outer surface of the heel refers to the surface of the heel furthest from the center of the cyclotron.

Referring to FIG. 3, the first moving member 110 and the second moving member 120 of the present invention include a first support 111, a second support 112, a conveyor belt 113, A first conveyor drum 114, a second conveyor drum 115, and a first motor 160. Also, the first moving member 110 and the second moving member 120 may be formed symmetrically with each other in the same configuration, same shape, and same size.

Hereinafter, the conveyor belt 113 included in the first moving member 110 is referred to as a first conveyor belt 113, and the conveyor belt 113 included in the second moving member 120 is referred to as a second conveyor belt Respectively.

3 shows the first moving member 110, but the second moving member 120 has the same configuration as the first moving member 110 and has the same shape. The first support 111 and the second support 112 have the same height and support the first conveyor drum 114 and the second conveyor drum 115, respectively. A first receiving portion is formed at a first height of the first supporting frame 111 so that the first conveying drum 114 can be received and rotated. Also, the second support base 112 may have a second height at the same height as the first height, and the second conveyor drum 115 may be accommodated therein to rotate.

The guide rails 130 may be stopped at a specific position by stoppers 116 and 117 which are moved by the conveyor belt 113 on the first and second support rods 111 and 112 . Sensors 118 and 119 for detecting contact with the guide rails 130 are disposed on one surface of the stoppers 116 and 117 contacting the conveyor so that the guide rails 130 contact the one surface of the stoppers 116 and 117 So that it can be sensed when it stops. Hereinafter, the stopper included in the first support base 111 will be referred to as a first stopper 116, and the stopper included in the second support base 112 will be referred to as a second stopper 117. [

The first conveyor belt 113 and the second conveyor belt (not shown) of the present invention are connected to the first conveyor drum 114 and the second conveyor drum 115, and the first conveyor drum 114 and the second conveyor belt 114 And can be horizontally moved by the rotation of the conveyor drum 115. [

The first motor 160 of the present invention can provide a driving force so that the first conveyor drum 114 is rotated in the axial direction. The first motor 160 is a kind of piezoelectric motor. The piezoelectric elements included in such a piezoelectric motor may be formed of ceramics so as not to be influenced by the electromagnetic field. Preferably, lead, zinc, and titanium are mixed at a certain ratio Compound (PZT).

The first motor 160 is connected to both the first conveyor drum 114 of the first moving member 110 and the first conveyor drum 114 of the second moving member 120, The conveyor belt 113 of the first moving member 110 and the conveyor belt 113 of the second moving member 120 may be simultaneously driven to move the guide rail 130 vertically to the conveyor belt 113.

According to the first embodiment of the present invention, the guide rails 130 are disposed on the upper surface of the conveyor belt 113, and the guide rails 130 are moved together with the conveyor belts 113 in the second axial direction 2 and 3 are moved in the Y-axis direction).

The sensor carrier 140 includes at least one sensor 150 for measuring a magnetic field inside the cyclotron, is connected to the second motor, and is driven by the second motor. The sensor carrier 140 includes at least one wheel to be moved in contact with the guide rail 130 and can be reciprocated along the guide rail 130 in the second axial direction.

According to the present invention, the sensor 150 included in the sensor carrier 140 may be a Hall sensor for measuring a magnetic field inside the cyclotron.

4, the conveyor belt 113 is moved in the X-axis direction, and the sensor carrier 140 can be moved in the Y-axis direction along the guide rail 130. For example, when the guide rail 130 is moved to the right according to the movement of the conveyor belt 113, the sensor carrier 140 can reciprocate up and down. That is, the electromagnetic field inside the cyclotro can be measured in such a manner that the sensor carrier 140 is moved to the right while moving up and down.

According to the first embodiment of the present invention, the sensor carrier 140 and the guide rail 130 may also be made of a material which is not affected by the electromagnetic field inside the cyclotron. Preferably, the sensor carrier 140 and the guide rail 130 may be made of a material including at least one of titanium and aluminum.

According to the first embodiment of the present invention, the second motor for driving the sensor carrier 140 may also be a piezoelectric motor, like the first motor 160. The features and configuration of the second motor are the same as those of the first motor 160, and a detailed description thereof will be omitted.

Hereinafter, a driving process of the cyclotron magnetic field measuring system according to the first embodiment will be described.

The control unit (not shown) of the cyclotron transfers the first driving signal to the first motor 160 and the second motor (not shown). The first motor 160 and the second motor, which have received the drive signal, are simultaneously driven.

As the first motor 160 is driven, the first conveyor belt 113 and the second conveyor belt (not shown) move in the first axial direction (e.g., X-axis, horizontal direction). The first conveyor belt 113 and the guide rail 130 disposed on the upper surface of the second conveyor belt (not shown) are moved in the first axial direction along the first and second conveyor belts. As the guide rails 130 are moved, the sensor (included in the sensor carrier 140) is also moved in the first axial direction.

As the second motor is driven, the sensor carrier 140 reciprocates along a guide rail 130 in a second axial direction (e.g., Y-axis, up and down) perpendicular to the first axis. As the sensor carrier 140 reciprocates, the sensor 150 is also reciprocated in the second direction.

As a result, the sensor 150 moves simultaneously in the first axis direction and the second axis direction to measure the magnetic field inside the cyclotron.

As the conveyor belt 113 moves, the sensor carrier 140 can move toward the first support 111. At this time, the sensor carrier 140 comes into contact with one surface of the stopper disposed at the end of the first support 111. In this case, the sensor disposed on the stopper 116 of the first support 111 senses the contact between the guide rail 130 and the stopper 116 and transmits a contact sensing signal to the control unit.

When receiving the contact sensing signal, the controller generates a second driving signal and transmits the generated second driving signal to the first motor 160. The first motor 160 receives the second driving signal and simultaneously drives the first conveying drum 114 included in the first moving member 110 and the second conveying drum 120 in the opposite direction The sensor carrier 140 can be moved to the original position by moving the conveyor belt 113 in a direction opposite to the direction in which the conveyor belt 113 was originally moved.

(Second Example )

5, the electromagnet magnetic field measurement system of the cyclotron according to the second embodiment of the present invention includes a first moving member 110, a second moving member 120, a first sensor unit 170, (180), and a first motor (160). The first moving member 110 and the second moving member 120 and the first sensor unit 170 and the second sensor unit 180 are arranged to be perpendicular to each other.

Here, the first moving member 110, the second moving member 120, and the first motor 160 are the same as the first moving member, the second moving member 120, the first motor 160, The same description will not be repeated.

The first sensor unit 170 includes a first sensor moving member 171 and a plurality of sensors 151, 152 and 153. The second sensor unit 180 includes a second sensor moving member 181 and a plurality of sensors. Preferably, the first sensor moving member 171 and the second sensor moving member 181 have the same shape and the same size and are simultaneously moved in the same direction by the first moving member 110 and the second moving member 120 Can be moved.

The first sensor moving member 171 may include at least two sensors for measuring the magnetic field inside the cyclotron, and the sensors and the sensors included in the first sensor moving member 171 may be disposed at a first distance. For example, referring to FIG. 6, three sensors 151, 152, and 153 may be disposed at a first distance in the first sensor moving member 171.

The first sensor 151 included in the first sensor moving member 171 is disposed on the outer surface of the first heel 21a and the fourth sensor 154 is disposed on the outer surface of the first heel 21a, So that the magnetic field of the entire sector portion 21 can be sensed by being disposed on the outer surface of the second heel 21b.

The second sensor moving member 181 may include at least one sensor for measuring the magnetic field inside the cyclotron. The sensors 154 and 155 included in the second sensor moving member 181 can be disposed at positions corresponding to the distance between the sensor and the sensor to the first moving member 110. [ That is, a sensor disposed in the second sensor unit 180 to sense a magnetic field not sensed by the first sensor unit 170 may be disposed at a distance between the sensor of the first sensor unit 170 and the sensor.

The sensors 151, 152, 153, 154 and 155 included in the first sensor moving member 171 and the second sensor moving member 181 are connected to the first sensor moving member 171 and the second sensor moving member 181). ≪ / RTI > 5, when the first sensor moving member 171 and the second sensor moving member 181 are moved to the right, the first sensor moving member 171 and the second sensor moving member 181 are moved in the right direction, The sensors disposed on the upper and lower sides can be arranged up and down.

6, the first sensor 151, the second sensor 152, and the third sensor may be included in the first sensor moving member 171, and the fourth sensor 154, the fifth sensor 152, 155 may be included in the second sensor moving member 181. The first sensor 151 and the second sensor 152 may be disposed at a first distance and the second sensor 152 and the third sensor 153 may be disposed at a second distance. The fourth sensor 154 may be disposed at a position corresponding to a first distance that is a distance between the first sensor 151 and the second sensor 152 and the fifth sensor 155 may be disposed at a position corresponding to the second sensor 152, The third sensor 153 may be disposed at a position corresponding to a second distance that is a distance between the third sensor 153 and the third sensor 153. [

In the conventional cyclotron magnetic field measuring system, there is a problem that the sensing accuracy is low because the sensing member in which the sensor is disposed rotates in a predetermined direction, and thus there is a region that can not be sensed. However, according to the sensor arrangement according to the second embodiment, The second sensor unit 180 senses a magnetic field that has not been sensed by the first sensor unit 170, which is advantageous in that the magnetic field inside the cyclotron can be measured more precisely than in the prior art.

In the conventional cyclotron magnetic field measurement system, the driving unit for moving the sensing member and the driving unit for rotating the sensing member are required. However, according to the second embodiment, the first moving member 110 and the second moving member 120 are simultaneously Since only one motor that can be moved is needed, there is also an advantage that the number of motors can be reduced and thus the compactness of the cyclotron can be achieved.

According to the second embodiment, the first sensor unit 170 and the second sensor unit 180 are disposed at a predetermined interval, so that the first sensor unit 170 is first moved in the first direction , And the second sensor unit 180 moves after a predetermined time interval.

The control unit of the cyclotron previously sets the time at which the first sensor unit 170 and the second sensor unit 180 are moved and the departure time of the first sensor unit 170 and the second sensor unit 180 is stored in the control unit .
