Jefferson Lab Fast Ion Chambers
D. Dotson, K. L. Mahoney
Fast ion chambers designed specifically for radiation protection have been in use at the Jefferson Lab for over 5 years. In the ensuing time, the chambers have become the instrumentation of choice for traceable high reliability, high radiation beam loss measurements. The chambers, which feature a 6 decade calibrated range, include an integrated adjustable high voltage power supply, analog output, contact/fiber optic fault outputs, as well as built-in self test functions. This paper describes the construction of the Jefferson Lab fast ion chambers and presents field data for several of the applications for which the chambers are used.
