Description:
After successful demonstration measurements with the Scintillation Profile Monitor (SPM) at COSY, a dedicated vacuum chamber with two vacuum windows and supporting vacuum ports was installed in the COSYsynchrotron. The chamber is blackened inside to suppress light reflection. Since residual gas pressure is too low to support reliable profile measurements based on beam induced scintillation, a piezo-electric dosing valve wasinstalled allowing fast injections of defined amount of nitrogen. A 32-channel photomultiplier is used to detect light. Beam profile measurements and first experience are reported.
