Radiation

Feb 10: At the 2024:041:03:30 comm, SCS-107 was manually run in order to safe the science instruments in light of high GOES 3-11MeV radiation rates. These rates are used as a proxy for the HRC shield rates and indicated an expected background rate of over 250,000 cps which is above the design limit. The SCS ran nominally. The GOES rates had increased sharply earlier in the day, following an X3.3 flare on the western limb. The team met at 11 am EST Feb 10. At that time ACE P3 rates were still acceptable, GOES rates were too high to activate HRC, but were acceptable if HRC were left inactive. A weak but prolonged CME was expected to be impactful from about 1200z Sunday to ~1200z Monday.

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:	5.214e-02 CTI/year	(1.428e-04 CTI/day)
Detrended slope:	4.865e-02 CTI/year	(1.333e-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, 0 peaks are observed.

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

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.
