“…The largest HgI 2 detectors currently available are in the planar configuration and are 1 cm thick by 3 cm in diameter (Hull et al, 1983). This is small compared with Ge detectors, but is an improvement over the millimeter thick detectors of the 1970's.…”

Basic principles of operation and characteristics of scintillation and semi-conductor detectors used for solar hard X-ray and gamma-ray spectrometers are presented. Scintillation materials such as NaI offer high stopping power for incident gamma rays, modest energy resolution, and relatively simple operation. They are, to date, the most often used detector in solar gamma-ray spectroscopy. The scintillator BGO has higher stopping power than NaI, but poorer energy resolution. The primary advantage of semi-conductor materials such as Ge is their high-energy resolution. Monte-Carlo simulations of the response of NaI and Ge detectors to model solar flare inputs show the benefit of high resolution for studying spectral lines. No semi-conductor material besides Ge is currently available with adequate combined size and purity to make general-use hard X-ray and gamma-ray detectors for solar studies.

“…Current detectors are, however, nowhere near this limit, with typical resolution of 60 keV at 662 keV for 1-cm thick crystals (Hull et al, 1983) compared with 1-2 keV for Ge and 40-50 keV for NaI. The principal causes are charge trapping combined with low hole mobility.…”
