First experimental tests of a single pass non-destructive monitor of the linear charge density in an intense relativistic bunch have been held at the Budker INP in Novosibirsk. The method is based on the scanning of deflections of a thin, low current and continuous electron beam in the electromagnetic field of an intensive relativistic bunch. The data processing after such measurements results in the instantaneous linear charge distribution of the tested bunch. The probe beam-with particle energies within the range 20-100 kV-was injected in the vacuum chamber of the accelerator in the direction perpendicular to the motion of the tested intensive relativistic bunch. This type of an electron beam probe is suitable for both circular and linear accelerators with sort intense particle bunches.
