Improved Data Acquisition Applying the Digitization Technique to Nuclear Experiments

Rapid growth in computing performance and nearly unlimited storage capacity has stimulated the use of waveform digitizers as a new technique for nuclear experiments. This method has advantages compared to standard analogue techniques. Presently, we are implementing the digitization technique in measurements of prompt fission neutron emission in coincidence with the fission fragments of the spontaneous fission of 252Cf. As detector a twin Frischgrid ionization chamber is used, together with NE213 liquid scintillation detectors for the neutron registration. Preliminary results show that the procedure works and a good agreement of the fission fragment mass distribution with literature values is obtained.JRC.D.5-Neutron physic
