COMPENSATED ION CHAMBER
Summary
Compensated ion chambers are summarized below.
Compensated Ion Chamber Summary
A compensated ion chamber has two concentric cylinders: a boron-coated
chamber and an uncoated chamber.
Both gammas and neutrons interact in the boron-coated chamber.
Only gammas interact in the uncoated chamber.
The voltages to each chamber are set so that the current from the gammas in the
boron-coated chamber cancels the current from the gammas in the uncoated
chamber.
