Monitoring system for relativistic particles and nuclei

The techniques and applications of a monitoring system of relativistic particles and nuclei accelerated at the Dubna synchrophasotron are described. The proposed technique allows one to measure a beam of charged projectiles over a wide range of intensities without any noticeable dependence on the beam profile. The technique was applied to calibrate the systems for measuring the absolute intensity. It facilitated the determination of the total cross sections of monitoring reactions 27Al(p,X)24Na and 27Al(12C,X)24Na at 3.65 AGeV with a sufficient accuracy for the beam flux monitoring by the well-known foil activation technique.
