Subject:
NSA/AERI/C1 - AERI extended range detector at Barrow
DataStreams:nsaaerisummaryC1.a1, nsaaeriengineerC1.a1, nsaaerich1C1.a1, nsaaerich2C1.a1
Description:
The extended range detector had failed and a borrowed replacement detector was installed. 
The replacement detector had enough air present in the dewar to cause the cryogenic 
cooler to work at full current. The detector was still warmer than optimal and there is more 
noise present in the data than is considered normal. The data must be used with 
discretion. The system was shut off on 020516 due to noise and rising detector temperatures.
