Properties of the Channel Electron Multiplier Arrays (CEMAs) for the SOLEX Solar X-Ray Spectrometer/Spectroheliograph
Abstract
A Channel Electron Multiplier Array (CEMA) detector was launched on 24 February 1979 as part of the SOLEX Solar X-Ray Spectrometer/Spectroheliograph experiment aboard the U.S. Air Force Space Test Program P78-1 satellite. Since launch, this detector has successfully recorded X-rays in the 3-25 A wavelength range. This report describes the comprehensive laboratory testing program of the flight and flight spare CEMA detectors. Quantum efficiencies, energy resolution and gain are given as a function of different incident photon wavelengths, voltage configurations, incident angles and lifetime exposures. Our results are compared to other published values.
