Meter of three-dimensional distribution function of beam particle density of a linear accelerator

The possibility of creating the device for measuring the function of particle density distribution in real time is considered./ The device is based on the phase spectrum analyzer - the instrument for measuring longitudinal charge distribution in clusters. The analyzer inlet collimator is accomplished in form of a hole lesser in size as compared to the beam cross section and may be transferred in parallel with the analyzer target. The three-dimensional functions of particle density distribution may be achieved through shifting the inlet collimator and the target and measuring in each case the phase spectrum. 7 refs. 4 figs
