| Summary: | Methods for monitoring the intensity of the external proton beam from the 100 Mev McGill Synchrocyclotron were investigated. By using the Faraday Cup and the ionization chamber, it is possible to measure the beam current over a range 10^-14 amp. to 10^-8 amp. An integrator circuit providing the suitable ranges was built and calibrated to 0.4% accuracy. For low beam intensity, high background and short burst experiments, the C11 activation method is recommended. The cross section for C11 activation has been measured to be (63.8 +0.8/-0.6) mb for 96 Mev protons. This will then provide an additional accurate monitor for beam intensity. |
