CALIFORNIA INST OF TECH PASADENA
Pagination or Media Count:
The instrument is used to measure fast neutron and gamma radiation levels around the ONR 10-Mev tandem accelerator at the California Institute of Technology. It has 12 channels, two for each of six monitoring stations, recording gamma radiation and neutron flux separately. It is wholly transistorized, and features a single logarithmic ratemeter scale and warning system for each channel. It consists of three chassis installed in the control console, one containing the complete power supply unit, the others containing the ratemeters and warning circuits for the neutron and gamma channels. There are two detector units at each monitoring station housing detector tubes and preamplifiers.
