Eberline R0-7 Ion Chamber


 

Overview:

An Eberline R0-7 Ion chamber is modified to span ragnes of 200R/h to 20MR/h for measurements of bermstrahlung x-ray dose rates inside an industrial electron beam irradiator. Origionaly the meter was capable of reading dose rates up to 20kR/h, however modification of the feedback resistor gains allows operation at a higher range.
