Hot Plasma Composition Experiment (HPCE)

NSSDCA ID: 1984-088A-01

Mission Name: AMPTE/CCE
Principal Investigator:Dr. David M. Klumpar


This instrument consisted of an entrance collimator and retarding potential analyzer, a curved-plate electrostatic energy analyzer, and a combined electrostatic-magnetic mass analyzer in series. The energy range covered was approximately 0 to 17 keV/Q, with a geometric factor ranging from 0.01 to 0.05 sq cm-sr, an energy resolution from 6 to 60%, and an M/Q resolution of 10%. This instrument cleanly separated Li+ and Ba+ tracer ions from the background. It was nearly identical to one flown on DE 1 by the same group of investigators. An additional set of eight spectrometers containing permanent bending magnets and channeltrons measured electrons in eight channels from 50 eV to 25 keV. For more details, see E.G. Shelley et al., IEEE Transactions on Geoscience and Remote Sensing, v. GE-23, p. 241, 1985.
