  2. RPS Health Summary Both instruments are fully functional with no performance issues Thermal management is nominal One occurrence of a fast glitch (<50nsec risetime) on RPS-A 1PPS line 4/26/2014 (day 605) at 0934Z Occurred at apogee (L=5.77, MLT=10.24) during a relatively weak outer zone enhancement RPS-B 9/1/2011 to 9/1/2014

  3. RPS Extended Mission Items RPS measurement of total ionizing dose is an important contribution to questions about vehicle health ~6.7 rads per day behind 540 mils ~2.4 krads per year New operations mode option: Modify coincidence to not require triggers of back detectors The change would lower the incident energy requirement for protons from 60 MeV to ~30 MeV depending on the exact mode Would be done in campaign modes to provide a larger overlap between RPS and REPT
