2. RPS-B
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
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
