The IMPACT investigation for the STEREO Mission includes a complement of Solar Energetic Particle instruments on each of the two STEREO spacecraft. Of these instruments, the High Energy Telescopes (HETs) provide the highest energy measurements. This paper describes the HETs in detail, including the scientific objectives, the sensors, the overall mechanical and electrical design, and the on-board software. The HETs are designed to measure the abundances and energy spectra of electrons, protons, He, and heavier nuclei up to Fe in interplanetary space. For protons and He that stop in the HET, the kinetic energy range corresponds to ∼13 to 40 MeV/n. Protons that do not stop in the telescope (referred to as penetrating protons) are measured up to ∼100 MeV/n, as are penetrating He. For stopping He, the individual isotopes 3He and 4He can be distinguished. Stopping electrons are measured in the energy range ∼0.7–6 MeV.

Additional Information:© Springer International Publishing AG, Part of Springer Science+Business Media. We wish to thank the STEREO Mission Project Office at GSFC for their extensive support. Haydee Maldonado was the initial STEREO Project Manager, a role subsequently passed to Nick Chrissotomos. Mike Delmont was the Deputy Project Manager. Joe Davila was the initial STEREO Project Scientist, followed by Mike Kaiser.We thank each of them for their support.We especially wish to acknowledge Lillian Reichenthal, the STEREO Project Instrument Manager for IMPACT, who was a staunch supporter and active member of our team. She prodded us to look at the big picture (schedule, schedule, schedule!) when we were mired in details, and assisted us on a daily basis. Other support from the Project Office was provided by Harry Culver, Therese Errigo, Larry Gibb, Fred Gross, Jerry Hengermihle, Shane Hynes, Mike Jones, Diane Kolos, Tabitha Merchant, Bobby Power, Antonio Reyes, and Steve Wasserzug. We also wish to thank many individuals at the Johns Hopkins Applied Physics Laboratory (APL), some of them unknown to us, for their support as the spacecraft contractor. In particular, we wish to thank Andy Dreisman, the Deputy Project Manager at APL, and Dave Myers, the primary APL contact for IMPACT. Possible detector contamination by low-level volatile fumes was a constant issue that APL handled effectively. We wish to thank various individuals at the University of California at Berkeley (UCB). Janet Luhmann is the IMPACT Principal Investigator and we thank her for her active encouragement and support. David Curtis was the IMPACT project manager at UCB. His long professional experience, his easy-going manner under fire, and his ability to keep on top of many different complex issues all at the same time were invaluable to us. Other support has been provided by Peter Berg, Selda Heavner, Ron Jackson, and Peter Schroeder. Finally, we thank Eric Christian, the STEREO Program Scientist at NASA Headquarters, both for his administrative support and encouragement, but also for his willingness to take night shifts for spacecraftlevel thermal vacuum testing which required 24 hours per day/7 days per week coverage for approximately a month.
