The UH-Nuclei Cosmic Ray Detector on the Third High Energy Astronomy Observatory

Abstract

The third High Energy Astronomy Observatory satellite (HEAO-3) carries a particle telescope for the detection of highly charged cosmic ray nuclei. These nuclei, which have Z ≳ 28, are much rarer than the lower charged nuclei in the cosmic radiation. As a consequence, this particle telescope was required to have a large collecting area as well as an ability to resolve individual elements. This paper describes the telescope, composed of large area parallel plate ionization chambers, multiwire ion chamber hodoscopes and a Cherenkov radiation detector. The resulting telescope has a total geometry factor of 59,000 cm^2 sr and is capable of measuring the charges of nuclei in the range 14 ≲ Z ≲ 120.

Copyright © 1981 Published by Elsevier. The design, fabrication and testing of an instrument such as this is the product of the dedicated efforts of a large number of people, only some of whom can be recognized by name. However, we must thank for engineering assistance, V. M. Noble, W. A. Gneiser, H. A. Chameroy and C. SPringer of BASD, J. W> Epstein of WU, W. G. Blodgett of CIT and W. Erickson, G. Peterson and R. Howard of UM. Management of this program was under NASA Marshall Space Flight Center and we acknowledge with thanks the continued assistance of personnel at that Center. The excellent performance of the HEAO spacecraft owes much to the personnel of TRW to whom we are deeply indebted. Funding for this instrument was supported in part by NASA under Contracts NAS8-27976, 7, 8 and grants NGR 05-002-160, 24-005-050, and 26-008-001.
