The Model WM3210 Passive/Active Neutron (PAN) Shuffler system uses a high speed transfer mechanism to shuffle a 252Cf interrogation source between a source shield assembly and the counting chamber, giving it the ability to be used for both passive and active neutron coincidence counting of fissionable materials.
The Features
- Unique 252Cf Shuffler mechanism for both Active and Passive neutron coincidence counting of 200 L drums
- Active mode sensitivity1, 1000 second count time:
- Fast neutrons: 300 mg 235U
- Thermal neutrons: 3 mg 235U
- Passive mode sensitivity, 1000 second count time: 4 mg 240Pu
- Rugged mechanical design for in-plant use
- Fast Teleflex source shuffling mechanism with 400 ms transfer time
- Three rpm turntable for barrel rotation
- Sixty-four 3He tubes for 17.5% detection efficiency
- PC-based control and analysis system
