Radiation

At 2021:301:16:35:54 UTC, SCS-107 ran due to a high radiation event very shortly after an X-1 class X-ray flare seen by GOES. The RADMON trigger was the ACIS TXings monitor. The SCS-107 run was nominal and the science instruments were left in a safe and expected configuration, with the science observing loads stopped and vehicle loads still running.

Detrended CTI

Although we prefer to quote CTI values of the cleanest data (FT <= -119.7 C, int time > 7000sec), the data that fulfills these conditions are getting rare. We now quote CTI based on temperature corrected data for Focal plane temperature <= -118.5 C).

The unit is now CTI/year not CTI/day.

Average of ACIS-I CCDs (MnKa) slope:	5.518e-02 CTI/year	(1.512e-04 CTI/day)
Detrended slope:	6.019e-02 CTI/year	(1.649e-04 CTI/day)

ACIS Warm Pixels

We display all bad pixels that have showed up in past, and, if any, previously unknown bad pixels appeared in the last 14 days. We also list hot pixels (defined as 1000 above the average of bias background). Warm columns 509-514 are probably due to boundaries.

New definitions of warm pixels and flickering pixels (May 15, 2014). If a pixel displays the level beyond a threshold for more than 70% of the time in the past two weeks, the pixel is categorized as a "warm" pixel. If a pixel is above the threshold more than 30% of time but less than 70% of the time in the past two weeks, the pixel is categorized as a "flickering" pixel.

ACIS Focal Plane Temperature

For this period, 8 peaks are observed.

Day (DOY)	Temp (C)	Width (Days)

294.88	-114.54	0.43

300.41	-96.64	0.69

Weekly focal plane temperature with sun angle, earth angle, and altitude overplotted. Sun angle is the solar array angle, that is the angle between the sun and the optical axis (+X axis). The earth angle is the angle between earth and the ACIS radiator (+Z axis). Altitude varies from 34 kkm to 128 kkm.
