It crosses front end region and smoothly reaches light beam line and experiment centre.Photon optical gate can self-movement control use be to be directly related to light beam line
Can experiment centre enter safely optics shed, it is the important component of entire light beam line experiment centre safety interlocking.
In front end region setting, there are two photon optical gates for the existing front end region Canted for having built completion, and by every
A light beam line corresponds to a photon shutter device independently to realize the independent control of two light beam lines.Due to the angle of two light beams
It is relatively large, it can be divided by being divided aperture device in front end region, and then realize being kept completely separate for two light beams, two
Light beam passes through corresponding photon optical gate respectively again.

Light trap unthreaded hole, as soon as while realizing the Beam Control to the front end region Canted of extra small angle, an other light beam
It can be blocked by photon optical gate, cannot smoothly reach downstream light bunch and experiment centre；In addition, because Canted light beam line is insertion piece
The power of light source, light source is very big, and it is abnormally dangerous that light beam, which is directly got on light beam line on light passing equipment end face or tube wall,
Thing, it is possible to can be because power be excessive that equipment damage be caused to lead to vacuum leak.Since light source is run to entire front end region
With ultrahigh vacuum requirement, once there is vacuum leak, control chain reaction just will start, storage rings are carried out to kick beam protection, storage
It deposits ring and once kicks beam, will affect the normal operation at other light beam line stations.Simultaneously because front end region is in the environment of radiation, if hair
Raw vacuum leak, not only ultra-high vacuum environment is destroyed, while the equipment in front end region downstream and the safety of the person also will receive
It threatens.
For at present in the front end region Canted for the extra small angle built for, two light beam lines can not be complete in front end region
It separates, whether required photon optical gate will not only consider that a light beam line realizes individually control light passing, while also to consider not
It can influence the use of an other light beam line.In conclusion developing the new photon suitable for the front end region extra small angle Canted
Optical gate is very urgent key task.
