Run number 1: Shorttest@10,IV@10
Run number 2: Shorttest@10, IV@10,Cycle(n=1, between 10 and -10), Shorttest@10, IV@10
Run number 3: Shorttest@10, IV@10, Cycle(n=5, between 10 and -10), Shorttest@10, IV@10
In runs 1 and 2, IV was done from -5 to -155 in steps of 10
In run 3, IV was done from -5 to -405 in steps of 10
No issues were observed during the tests themselves.
Running MoReWeb shows the Temperature, Humidity and Sum of Currents plots while individual tests show only Pixel Alive map. IV plot is missing in the MoReWeb output, however, it is present in the ivCurve.log file. Tried investigating why IV is not shown, but couldn't get to the bottom of it.
Tomorrow we'll use M1529 and M1530 in a FullTest to check if the problem would appear. |
M1530 was put in the coldbox and qualification was started, but the pxar output was full of deserializer errors. The continuous stream of errors made the log file pretty large and slowed down the execution of the qualification so it was aborted. Later it was noticed that there are green depositions on the module like it was on the HDIs irradiated at 60Co facility in Zagreb which is probably why there were so many errors.
M1521 was used instead of M1530 along with M1529. Full qualification was launched around 11:00. |
