From this month, we report CTIs with a refined data definition. CTIs were computed for the data taken during the focal plane temperature < -119.7 C, and the integration time longer than 7,000 sec. This eliminates a CTI temperature dependency, and the shows CTI degradation with time much more cleanly. Please see new CTI page for detailed explanation. CTI's are computed for Mn K alpha, and defined as slope/intercept x10^4 of row # vs ADU. Data file here
CTI slopes were computed for data point after DOM 200 and inside of 1 sigma deviation. Using only data point in 1 sigma range, we drop high temperature observations, squeegy observations, and other outliers. A independent variable is date, and a dependent variable is CTI.
Note: Because of refined data sets, the fittings are much better and CTI slope values are quite different from the last month (about 0.5e-9 differences in many cases).Front Side Illuminated S Array Node 0 Node 1 Node 2 Node 3 CCD4 9.575e-9 1.210e-8 1.252e-8 1.117e-8 CCD6 9.139e-9 9.703e-9 9.992e-9 9.209e-9 CCD8 8.062e-9 8.680e-9 8.275e-9 7.941e-9 CCD9 9.161e-9 1.076e-8 1.093e-8 7.724e-9 AVG 9.075e-9 Front Side Illuminated I Array Node 0 Node 1 Node 2 Node 3 CCD0 6.894e-9 8.645e-9 8.939e-9 7.360e-9 CCD1 7.327e-9 8.342e-9 8.300e-9 6.392e-9 CCD2 7.378e-9 8.749e-9 8.431e-9 6.876e-9 CCD3 6.944e-9 8.616e-9 8.589e-9 7.555e-9 AVG 7.331e-9 Back Side Illuminated S Array (not detrended) Node 0 Node 1 Node 2 Node 3 CCD5 3.335e-9 3.492e-9 3.530e-9 2.474e-9 AVG: 3.103e-9 CCD7 2.141e-9 2.984e-9 3.099e-9 2.002e-9 AVG 2.565e-9

We collected data from acis histogram mode data, and created trend plots of peak portions and peak widths against time (DOM). The peaks were estimated by fitting a simple Gaussian on three peaks (Al, Ti, and Mn), and the widths were estimated by a width at the half max from the peak.
All histogram data are taken under TIMED and GRADED_HIST mode, SIM position is at an external calibration source position, the focal temperature is around -119.7 C, and paramter settings in aciselec, acistemp are set to about same for all.

We display a max dose trend plot corrected for events that "pile-up" in the center of the taps due to bad position information.
