Magnetic electron multipliers: efficiency changes.
During the mission of AEROS-A satellite the recorded calibration data exhibited a strong variation of the magnetic electron multiplier efficiency. Drastic changes do correlate with temperature; however, a clear separation of the temperature effect cannot be derived from the measurements. In space they have been impeded, e.g., by long-term efficiency changes, while in the laboratory ion feedback and other effects interfered with the measurements. The results affect the design of future space experiments especially for solar XUV measurements.
