SCINTILLATION HODOSCOPE FOR ACCELERATED BEAMS

A system is described for detecting optical radiation in order to meas ure the transverse dimensions of beams and their particle density dist ribution. The system is based on hodoscope photomultipliers, scintilla tors, fiber-optic transmission lines, and electronic units. The system was designed for monitoring beams of elementary particles in the K4-K 10 c-tau-factory accelerator-storage systems, the synchrophasotron, an d the nuclotron, with energies of 20 MeV to 10 GeV and intensities of 10(3)-10(8) particles/cm(2). A brief description is given of the optic al part, the design of the detector, and the hardware and software.
