The high energy beam and the RF-separator for BEBC at the CERN-300 GeV

A RF separated beam for BEBC using a target located in the epb tunnel at the maximum distance from BEBC is described. As it has been shown that BEBC is a useful detector for strong interaction physics up to the 100 GeV/c region of incident momenta, it is intended that the beam will separate masses the highest possible momenta (73 GeV/c K- pi ), that are a reasonably clear extension of present techniques. It is also intended to give the first part of the RF beam in the epb tunnel the capacity to transport the major part of the available proton flux to the West Area to provide a secondary target for a short neutrino beam or a lower energy separated beam installed on the floor of halls E1 and E3. The maximum unseparated momentum is 150 GeV/c. (3 refs)

Solid state detectors used for the CERN Neutrino Flux Monitoring (NFM)

The CERN neutrino beam is monitored via the accompanying muon flux in the iron shield. Silicon radiation detectors are used for measuring this flux at several places in the shield. Special features of the electronics are the low noise cable connection to the remote preamplifier and the leakage current compensation. The precise calibration of the detectors allows detailed information on the neutrino flux. Some aspects of the NFM system are reported especially the electronic chain, the detectors and the calibration. Some of the capabilities for on-line beam control and off-line data analysis are shown.
