Description
Technical field
This application involves accelerator dampening apparatus technical fields, and in particular to a kind of particle accelerator tuning quality vibration damping
Device.
Background technique
A storage rings electron energy of planning construction is 5GeV during Beijing high energy synchrotron radiation light source is " 13 ",
Emittance is higher than the high energy synchrotron radiation light source of 0.5nmrad.Entire synchrotron radiation light source includes booster and two type of storage rings
Type accelerator.The capital equipment of accelerator is that all kinds of magnet (include: dipolar magnet, quadrupole electromagnet, six pole magnet, correction magnetic
Iron), magnet holder is the equipment for supporting, adjusting, position all kinds of magnet, and Adjustment precision size directly affects all kinds of magnet
Alignment precision.
The vibration isolation of the particle accelerators equipment supporter such as synchrotron radiation light source and spallation neutron target or vibration insulating system design with often
Rule vibration precision equipment compares the technical problem for having many keys, is mainly reflected in the following aspects:
The first, the major function effect of accelerator facility bracket is to guarantee that accelerator facility conveniently, can be carried out accurately
Alignment, bracket need to be according to the adjustable oneself height of ground situation and forms, and the support construction of such bracket is complex,
It cannot be designed to simple rigid support, and the born pressure unevenness of each support may occur by collimation adjustment after-poppet
Even problem, so that bracket intrinsic frequency be caused to change, it is also possible to resonate with excited frequency；
The second, the installation that accelerator facility needs firm stable positions, it is ensured that equipment will not be because of accident in operation
It shifts, but most of vibration isolation components are all difficult to accomplish the firm installation of equipment, if the biggish vibration isolation of selection elasticity
Element, it is also possible to the amplitude of accelerator facility be caused to increase；
Third, accelerator facility running environment are mostly ray radiation environment, vibration isolation and damping material (especially damping material)
Conventional high-molecular organic material cannot be selected, vibration isolation element must have the requirement of radiation hardness long-term stable operation, and cannot send out
The raw short time acutely settles.

The absorption vibration ability of bracket is improved at the critical support position of bracket；By over the ground if European synchronous radiating light source (ESRF)
Surface vibration identifies vibration source inside and outside equipment with the vibration measurement for being total to frame magnet apparatus, is found on beam direction by analysis
Amplitude ratio is larger, and influence of the micro- vibration in ground to magnet holder is reduced by using the method for damping vibration attenuation.Shanghai light source
(SSRF) and the advanced light source of the Argonne in the U.S. (APS) etc. all uses damping sheet (Damp i ng at vertical support position
Pad) micro- influence of the vibration to equipment in ground is reduced.

The first, the method for Damper Braces is mainly used for solving the adverse effect of the vibrational energy bring from equipment, but such as
Fruit magnet apparatus Self generating oscillations power, Damper Braces are limited for the reduction ability of vibration force；
The second, Damper Braces can reduce the vibrational energy of all magnet on total frame bracket, but can not solve same
The magnetic force bring on frame bracket between different magnet vibrates influence problem altogether；
Third rigidly carries out vibration damping by increasing bracket, can not carry out effective vibration damping to low-frequency vibration；
4th, the restriction using vibration isolator vibration damping by working conditions such as support stability, the resistance to ray radiations of material, can not
Applied in particle accelerator.
Therefore, the prior art has much room for improvement and improves.
