SPECTROMETER FOR SOLAR-SYSTEM STUDIES

Abstract: We have developed a prototype spectrometer for space
applications that require long-term stable EUV photon flux
measurements. In this recently developed spectrometer, the
energy spectrum of the incoming photons is transformed directly
into an electron energy spectrum by taking advantage of the
photoelectric effect in one of several rare gases at low
pressures. Using an electron energy spectrometer operating at a
few electron volts, and followed by an electron multiplying
detector, pulses due to individual electrons are counted. The
overall efficiency of this process is essentially independent of
gain drifts in the signal path, and the secular degradation of
optical components that is often a problem in other techniques
is avoided.
