As the detectors age, it is important to increase the bias voltage to compensate for reduced sensitivity. This increase will improve the performance of the SEM TED sensor.

Topic:  Metop B (01) SEM TED Electron and Proton Bias Voltage Increase

Date/Time Issued:   September 20, 2016  0030Z Product(s) or Data Impacted:  SEM Data products

 Date/Time of Initial Impact:  September 21, 2016  09:08:34Z
 Date/Time of Expected End:   N/A Length of Outage:  N/A

Details/Specifics of Change:   Metop B SEM TED electron detector bias voltage will be increased by one count to level 2 and proton detector bias voltage by one count to level 3. This periodic change in the bias voltage is part of the normal operations of SEM and is not an indication of any problems.  As the detectors age, it is important to increase the bias voltage to compensate for reduced sensitivity. This increase will improve the performance of the SEM TED sensor.

This will occur on orbit # 20809.
