Subject:
NSA/AERI/C1 - NSA AERI cooler failure
DataStreams:nsaaeriC1.00
Description:
On April 19, 2001 the cryogenic cooler began to fail. Failure was complete by spectrum 
number 135 when the cooler current reached 3.26. Data from this point on are unusable. The 
instrument was shut off and there are no data from April 23-April 30. The cooler was 
replaced on April 30, 2001 and the instrument came back on-line May 1. After the initial 
start-up period, data are acceptable.
Suggestions: 
Do not use data from April 19 (#135) -April 22, 2001. Replacement of the cooler 

resolved this problem.
