Beschreibungen/Notizen

• We realized a prototype for a Beam Profile Monitor (BPRM) composed of 64 channels of scintillating and quartz fibers for the UA9 Experiment at CERN. The UA9 experimental equipment is installed in the CERN Super Proton Synchrotron (SPS) with the main aim of demonstrating the feasibility of using bent crystal as primary collimators in accelerators with the aid of the channeling effect. The aim of this BPRM is the measurement of particle fluence of the channeled beam during UA9 tests. The detector is made up of 256 0.5 mm round fibers arranged in four layers. A multi-anode photomultiplier supplies 64 optical channels readout. Vacuum/air mechanical interface is realized to house the BPRM in a secondary vacuum of a SPS Roman Pot. Signals are driven 20 meters away from the beam pipe where they are read by VME electronics readout boards. This prototype was installed in SPS at the end of June 2012 and first results are reported here. We plan to design and build on the basis of this BPRM a similar detector for the extension of UA9 program to the Large Hadron Collider (LHC).
