Pioneer 11 Trapped Radiation Detector (TRD) 30-m Count Rate Summary Data

2021-03-11 18:39:11Z

This ASCII data set contains 30-min count rates for
21 "pulse-counting" channels from a Cerenkov counter (which measures,
via 3 discrimination levels, electrons >6 MeV plus nuclei >480 MeV/n,
electrons >9 MeV plus nuclei >550 MeV/n, and electrons >13 MeV plus
nuclei >650 MeV/n), an electron scatter detector (nuclei >80 MeV/n
and electrons >0.16, >0.255, >0.46 MeV), and a minimizing ionizing
particle counter (nuclei >80 MeV and electrons >35 MeV. The data set
also contains 30-min averaged currents from the Cerenkov counter and
two scintillators, spacecraft position and attitude data, and various
other statistical and housekeeping data. The electrometer-based currents
data are not reliable. The data are all for mission cruise phases and
not planetary encounters.
