ACIS SOT Shift Report 2011-03-09 H4248 Duration: 9 Mar 2011 12:00am EDT - 9 Mar 2011 03:00am EDT ACIS Personnel: Mark Bautz, Bev LaMarr, Gregg Germain, Paul Plucinsky SUMMARY: -------- We intend to run CAP 1175 to collect DEA Housekeeping data with 10 video boards on from the I array and the S array. We will examine the I0 data at the beginning of the run to determine if the I0 data are nominal. All data from all CCDs looked nominal for the ECS measurement in the load, OBSID 55605. Most importantly the data from I0 looked nominal, the event rates looked fine, the threshold crossing looked fine,and the delta overclocks looked fine. We then stopped this run and powered up 10 video boards to start the next run. We executed an I array ECS measurement with the 10 video boards powered up. Again, all CCDs looked nominnal, in particular I0 looked just fine. MIT was able to verify that the voltages in DEA HKP were nominal. We then stopped this run and started an ACIS-S ECS measurement with 10 video boards powered up. Again, the voltages all appeared nominal. Our conclusion is that I0 and its video board are operating nominally. The problem with OBSID 12934 was temporary. The MAR0611 load may proceed as planned and there is no reason to adjust the observations in future weeks.
