TOWARDS ROUTINE OPERATION OF THE SCINTILLATION PROFILE MONITOR AT COSY

The cooler synchrotron COSY is currently equipped with two non-destructive beam profile monitors. One is based on ionisation and the other on scintillation of residual gas. The optics of the Scintillation Profile Monitor (SPM) was modified to correct the large error observed in previous measurements. Beam profile measurements were carried out after reinstallation in the COSY ring, showing good agreement with profiles, measured with the Ionisation Profile Monitor (IPM). Performance of the SPM is analysed. Application of the method in a proton synchrotron is discussed.
