The relative merits, including sensitivity to normal tunnel-alcove radiation environments, of two alternative Close-In Recording System CIRS concepts have been evaluated. Radiation hardened versions of the 7912 and 519SIT vidicon have been tested in the laboratory, at levels simulating environments encountered in the field. An optimized CIRS configuration, utilizing a hardened 7912, operates properly at the highest levels used, namely 2.5 - 3 rad absorbed dose. The 519 oscilloscope, by comparison, malfunctions at about 0.1 rad and the SIT vidicon at about 10 mrad, both due to direct target excitation. Author
