Van Allen Probes spacecraft VAP-A and -B, launched over a year ago [August 2012], carried 16 pMOS RADFETs into an orbit designed by NASA to probe the heart of the trapped-radiation belts. Nearly 350 days of in situ measurements from the Engineering Radiation Monitor (ERM) (a) demonstrated strong variations of dose rates with time, (b) found a critical correlation between its RADFET dosimeter and Faraday cup data on charged particles, and (c) mapped the belts by measuring variation with orbit… CONTINUE READING
