Abstract

This invention relates to accelerator technology. The purpose of the invention is to improve the accuracy of calibration. The calibration device contains a coil connected to an autonomous current pulse generator. The coil is located coaxially with the axis of the device with the possibility of changing the angle between the coil plane and the sensor axis. The calibration accuracy is increased by reducing the number of turns, which eliminates the effect of possible asymmetry of the device. In addition, this leads to a decrease in the device’s influence on the limit sensitivity of the sensor to be calibrated by changing the design of the calibration coil arrangement — the absence of inductive coupling between the calibration coil and the measuring windings of the sensor, which includes the calibration device, in the absence of a calibration process. This is especially important when the ratio of the number of turns between the calibration and measuring windings approaches unity. 1 il.

Description

The invention relates to accelerator technology and can be used to verify the operability and calibration of magnetic induction position-sensitive sensors of a beam of charged particles.

The aim of the invention is to improve the accuracy of the calibration.

The drawing shows variants of the electrical concept of a device for calibrating position-sensitive magnetic induction sensors with different positioning of sensor coils (a - the axis of the measuring coils are circumferentially oriented; b - the axes of the measuring coils are directed along the radii of their arrangement).

The device consists of coil 1, located coaxially to the U axis of the sensor with the possibility of changing the angle between the plane of coil 1 and the O axis of the sensor. Coil 1 is connected to generator 2 and the entire calibration device can be placed near the measuring coils. 3 sensors.

The device works as follows.

The calibration coil 1 is supplied with a pulsed current of an autonomous, calibration generator 2, in form and intensity similar to the current pulse of a charged particle beam. If the plane of coil 1 is orthogonal to the equivalent plane of the coils of the measuring coils 3 of the sensor (the initial state),

the signal at the output terminals of the coils 3 is zero, since inductive coupling is M1e; for orthogonally arranged turns of the two coils (in the particular case, turn 1 and coil 3) is absent. When calibrating the sensor, changing the angle by the plane of turn 1 relative to the coordinate axis X or Y, then the output signal of the corresponding opposite sensor coils 3 is proportional to the current of the calibration generator 2, the coupling coefficient between turn 1 and coils 3, which is proportional to the cosine of the angle between the turn plane 1 and the plane of the turns of the coils 3.
