Digital waveform analysis for /sup 3/He ionization chamber

Numerical analyzes on individual pulses from a cylindrical /sup 3/He gas ionization chamber have been performed. A radial distribution of the electron ion pairs was successfully analyzed by a deconvolution technique combined with a digital waveform analysis. From the charge distribution, clear separation of events of the reactions of /sup 3/He(n,p)T and /sup 3/He(n,n)/sup 3/He at the energy region of the /sup 3/He recoil edge was observed.
