Abstract :
We present the first experimental test of a singlepass non-destructive method of monitoring of longitudinal charge distribution in an intense relativistic electron bunch. This method is based on the scanning of a thin electron beam within the energy range 20-100 kV in the electromagnetic field of an intensive relativistic bunch. The probe beam was injected across the path of primary relativistic bunch. This type of an electron beam probe is suitable for both circular or linear accelerators. The prototype results obtained at VEPP-3 storage ring are in good agreement with the calculations and give us a very high degree of confidence that this single bunch diagnostic tool can be very useful not only for accelerator tuning, but also for precise measurements
