UHV Slits for SSRF






The high precision UHV slit systems were designed for

Shanghai Synchrotron Radiation Facility. There were total of nine slits with different aperture sizes. 


Each slit unit has 4 fiduciary marks provided. All UHV sections are vacuum tested to better than 5x10-10 torr and have a leak rate of less than 2x10–10 mbar l-1s-1.



All models use cross-roller bearing technology for exceptional straightness of travel. All of these slits use standard micro stepped stepper motors that could be controlled with a wide array of controllers/drivers available on the market. Our slits are being used in many synchrotrons around the world (APS, NSLS, ALS, DLS, NSRRC, BESSY, DESY, CHESS, ESRF, BSRF, CAMD, NSRL, PAL, LNLS, CLS, SSRF, IHEP, ANKA, KEK, ASP, SPring-8, ELETTRA, MAXLab, …)
