New fission fragment detectors for cross section and angular distribution measurements at CBNM
The accurate knowledge of the fission cross section of the highly active minor actinides belonging to the uranium based fuel cycle are of growing importance as the nuclear industry matures. For the measurement of such cross sections two fission fragment detectors are described which can be used in the presence of very high alpha backgrounds rates. For the understanding of the physics of the fission process, angular and energy distribution measurements can be helpful, for example for the determination of the quantum numbers J and K of the transition states. For this purpose as a detector was developed which has an angular efficiency of 2 ..pi.., an angular resolution of 5 % on cos theta, and energy resolution of 1.5 % and a timing resolution sufficient for the application in time-of-flight experiments.
