Fermi response 1. What make and model are you currently using? Canberra GEM5
2. Do you use a walk through or stand and count exit routine? Stand and count 3. What is the sensitivity to CS-137 and Co-60 that you are achieving and how does that compare to the manufacturers advertised sensitivity? easily meets INPO and EPRI RAM control performance criteria contact me directly if you want more technical details on sensitivity 4. Is the manufacturer easy to work with (technical support) and are parts easily accessible from them? Technical support has been excellent (there have been very few problems that required vendor support, mostly when new and our experience level was nil) Parts availability is SAT, our biggest maintenance issue has been hard drive failures 5. Does the calibration process make sense (calibration menu), is it efficient (easily accessible data display), and does it require any peripherals (printers etc...)? Very easy to calibrate, if you have Argos or Cronos equipment, same software is used. Menu's are a bit cluttered and tedious. Only peripheral needed is jump drive to copy cal files for printing (we hook up a mini external monitor during cal, so we don't have "strain" ourselves by having to move a few steps to use installed monitored. 6. Are they reliable? Yes, as mentioned, our most significant problem was hard drive failure, but it computer bay is kept clean, this problem should be minimized, we are moving to using solid state drives to replace disc drives, you might ask if new machines have solid state drives. 7. Are they easy to work on? Yes, although replacing modular detector board is tedious, this is rare failure, we have had two MDB failures since 2005, with eight GEM5, not a high failure rate Benjy Bertossi Fermi2 - RP Supervisor 734-586-4935 [email protected]
