Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
It is an object of the invention to provide a kind of device for improving the atom magnetometer relaxation time, solves atom in prior art
Inside absorption chamber, plating process is complicated, it is impossible to the technical problem of enough batch productions.
It is understandable to enable the above objects, features and advantages of the present invention to become apparent from, it is below in conjunction with the accompanying drawings and concrete real
The present invention is further detailed explanation to apply mode.
As shown in figure 1, the present invention provides a kind of device for improving the atom magnetometer relaxation time, including the cloud of some printing opacities
Master slice 2, the teflon plate 1 of some alternatively non-transparent and round bar 3, the mica sheet 2 are ring with the teflon plate 1
Shape, is provided with several the first rectangular channels 4, circumferentially symmetrical point of first rectangular channel 4 laterally in the inner circle of the mica sheet 2
Cloth, the inner circle of the teflon plate 1 are provided with several the second rectangular channels 5 laterally, and second rectangular channel 5 is circumferentially right
Claim distribution, first rectangular channel 4 is identical with 5 number of the second rectangular channel, the mica sheet 2 and the teflon plate
1 it is alternate with each other stack, the mica sheet 2 is provided with several connecting holes 6 with 1 outer circumference of the teflon plate, adjacent
The mica sheet 2 is rotated to an angle with the teflon plate 1 makes first rectangular channel 4 with second rectangular channel 5
Non-overlapping copies, the connecting hole 6 vertically form through hole, and the round bar 3 is through after the connecting hole 6 by the mica sheet
2 are fixedly connected with the teflon plate 1.
The device of the present invention is the supporting structure being made up of macromolecular material, is to absorb indoor in Cs atom in original technology
A floor height molecular material is plated in portion, usually polytetrafluoroethylene (PTFE), and the molecular weight of such material is much larger than Cs atom, with touching for Cs atom
Elastic-like collision is hit, and Cs atom is reduced by colliding the probability for changing energy level；And the supporting structure of the present invention is equally put
Inside Cs atom absorption chamber, but it is to be socketed in inside, by macromolecular material is made laminated structure, and then in stacking into
Between have through hole three-dimensional bracket structure, this special construction, by limit Cs atom diffusion motion, reduce Cs atom with inhale
The probability of chamber interior collision is received, the effect of internal coating, and process is simple can be equally reached, is easy to batch production.
Number such as Fig. 2 and 3, first rectangular channel 4 and second rectangular channel 5 is 8-12, the number of fluting
Less than the inner circle fluting portion of 8 purposes for then not reaching tissue atoms permeating, the mica sheet 2 and the teflon plate 1
The arc length divided is equal with the arc length of inner circle unslotted part；The connecting hole 6 is arranged on first rectangular channel 4 and described second
The outside of rectangular channel 5.
Internal diameter of the outside diameter of mica sheet 2 and teflon plate 1 for Atomic absorption room, mica sheet 2 and polytetrafluoroethyl-ne
The 2/5～3/5 of a diameter of outside diameter of the inner circle of alkene piece 1.
Such as, the caesium absorption chamber for conventional 25mmx25mm, mica sheet 2 with the outside diameter of teflon plate 1 is
A diameter of 10～15mm of the inner circle of 25mm, mica sheet 2 and teflon plate 1；The thickness of mica sheet 2 and teflon plate 1
Degree is 0.2mm, and adjacent mica sheet 2 and the spacing of teflon plate 1 are 0.5mm.
It is supporting structure that the present invention improves the device in atom magnetometer relaxation time, when support is assembled, by mica sheet 2 with
Together, and adjacent two thin slices need to hide fluting by the part of unslotted 1 interfolded of teflon plate
Position, the adjacent lighttight material of such a light transmissive material, but the position of fluting is due to light transmissive material mica sheet 2
The reason for, light can still shine in, but atom but plays certain inhibitory action when radial diffusion, but such as
Fruit mica sheet 2 is not slotted, although 1 slotted section of teflon plate can printing opacity, but so atom will be unable to diffusion, because
This, teflon plate 1 needs to slot simultaneously with mica sheet 2, and the number slotted is identical with shape, so rotates certain angle
After degree, unslotted part can be covered mutually with slotted section, and after the completion of stacking, round bar 3 is thin by what is folded through connecting hole 6
Piece is coupled together, and then is fixed and become support.Support is put into into Atomic absorption room in use, you can reach in atom
Absorption chamber plates the equivalent effect of macromolecular material, and replacing is more prone to, and is applied to batch production, significantly solves existing skill
The uneven coating that macromolecular material presence is plated in art is even, ropy problem.
Apply specific case to be set forth the principle and embodiment of the present invention in the present invention, above example
Illustrate that being only intended to help understands the method for the present invention and its core concept；Simultaneously for one of ordinary skill in the art, according to
According to the thought of the present invention, will change in specific embodiments and applications.In sum, this specification content
Should not be construed as limiting the invention.
