Abstract:

A second generation Dosimeter has been designed to fulfill the need for accurate radiation dose measurements. Two identical Dosimeters, a flight unit and a backup unit, have been fabricated, tested and calibrated. The backup Dosimeter was integrated into the payload of the Advanced Photovoltaic and Electronic Experiments APEX satellite, as part of the Photovoltaic Array Space Power Plus Diagnostics PASP Plus experiment. APEX was launched shortly after 1430 UT on 8394, with the initial orbit having apogeeperigee in the equatorial plane. The Dosimeter was turned on in Rev. 20, at about 0410 UT on 8594. The initial turn on showed no anomalies, with the Dosimeter operating properly. The Dosimeter was then monitored for several days and proper operation has been verified.
