PI: Dr. Jay Anderson Space Telescope Science Institute Y CoI: Dr. Sylvia M. Baggett Space Telescope Science Institute N CoI: Dr. Kai G. Noeske Space Telescope Science Institute N CoI: Dr. John W. MacKenty Space Telescope Science Institute N ------------------------------------------------------------------------------------ Abstract This internal calibration program will use the charge-injection capability of WFC3/UVIS to explore CTE losses as a function of position and charge-level across the detector. The idea is that the pixel-based CTE-reconstruction model we have in hand characterizes average CTE losses across the detector in terms of the number of traps in each column that affect each Nth electron in a pixel cloud. In actuality, the traps are not uniformly distributed across the detector: most pixels have no traps, but some pixels (probably) have several traps. In addition, the traps that are present are not all the same: some affect the first electron, some the second, some the hundredth, etc, depending on exactly where each trap lies within the silicon of the pixel relative to the resting or shuffling pixel cloud. We can use the charge-injection images to characterize the location and level of traps. The CI level puts about 15, 000 electrons into each injected column. In CI images with no background, we can study the losses in the injected column and the gains in the upstream trail to characterize where there are traps that grap the 1st through the 15, 000th electron. Most traps affect electrons below this, so this is a pretty broad characterization of the overall trap locations. We of course do not know exactly which pixel the traps are in, but we do know that there may be more in one column than in another, and we also know that there may be more in the first 200 pixels of a column than on average for that column. In addition to pinpointing roughly where the traps are, we can also do a similarly rough reckoning of where there may be more or fewer low-electron-grabbing traps than high-electron-grabbing traps. We can do this by post-flashing the CI images. If we take a variety of CI images with increasing levels of post-flash, we can take more and more of the low-traps off the table by looking at how the CI pixel gains and the trails lose with increasing post-flash level, we can also get a rough estimate of which traps are where. The observing plan is to take CI images with an array of background values (either from the post-flash on low or medium current): 0, 1, 2, 4, 6, 8, 10, 12, 15, 20, 25, 37, 45, 52, 60, 67, 75, 82, 90, 105, 120, 135, 150, 175, 200, 250, 300, 500, 750, 1000, 2000, 3500, 5000, 10000, 15000, 20000, and 28000 electrons. This amounts to 39 internal exposures. The hope would be to take them over the period of a couple weeks and also take some 13568( 3) - 04-Nov-2013 13:54:35 - [ 2] long-short dark pairs over roughly the same timeframe so that we can re-pin the CTE model one last time before we release it into the pipeline. We could also try to repeat the external CTE-validation images with the post-flash variation, so that we can make an additional demonstration of the efficacy of the new correction. ------------------------------------------------------------------------------------ Observations Description ------------------------ We will take charge-injection images with various levels of post-flash to characterize the distribution of traps in the detector. Real Time Justification ----------------------- We would like all these observations to be taken within a period of about two weeks. Ideally, they will also be taken close in time to that of CAL-13567, though that is not critical. It would also be nice to have these taken in between anneals. The anneals are scheduled for: 2013 Oct 7-13 2013 Nov 4-10 2013 Dec 2-8 2013 Dec 30 - 2014 Jan 5 2014 Jan 27 - Feb 2 2014 Feb 24 - Mar 2 2014 Mar 24 - 30 2014 Apr 21 - 27 2014 May 19 - 25 Calibration Justification ------------------------- These observations will provide a complementary way to study charge traps in the UVIS images.
