| Abstract: | A miniature fast fission chamber for use as start detector in time-of-flight measurement of 252Cf fission neutron spectrum has been designed.The total weight of the chamber was l,65g.The rise time of 6 ns and the detection efficiency of >99% , for fission fragments
were achieved at a source strength of 4.2X 103 fission/s. The paper
also gives the design principle of stich fission chamber and its
effects on fission neutron spectrum measurement. |
