Post 2016 Anneal Detector Operations

After the 2016 anneal, thermal considerations have led to the necessity of operating a subset of detectors at a time. This page describes the different modes for normal operations, times of high solar activity and campaigns. The document ends with a discussion of the different inputs and considerations in determining these modes.


Normal Operation

For thermal considerations, two detectors will be turned on and operated for normal data collection. At this time, D3 and D8, are the best candidates for general microflare studies.


Extremely Low Solar Activity

The thermal input from detectors and their electronics contribute significant heat input into the cryostat. It was suggested that under extremely quiet sun conditions we turn off all detectors for a short time so that we can drive down the cryocooler temperature. This option requires much further discussion and has not been agreed upon.

High Solar Activity

When the Sun is active and the forecast calls for heightened activity a third detector will be turned on for monitoring. At this time D1 and D9 are the best candidates for general monitoring.

Large Flare Observations

When the flare forecast calls for a Great Flare watch, enable more than 3 detectors for a short duration
