A versatile (e,2e) spectrometer has been successfully developed.The electron beam impacts with the gas beam at right cross. The position sensitive detector with micro-channel plate multipliers and resistive anodes have been developed.An on-line multi-parameter data acquisition technique and off-line data analysis are used.The distributions of separation energies and momentum profiles of Ar,He atoms and H2,CH4 moleculars have measured.
