Configuration/Radiation Overview for Oct 2003

Two very dynamic centers of activity emerged unexpectedly on the sun this month. The solar activities were the highest in the past 30 years. Observations were essentially stopped from Oct 24 - Nov 8 for a total lost science time of about 840 ksec. We may face more flares when these spots re-emerge on the face of the sun later in November. In addition, ACE apparently suffered damage to their real-time P2, P3, and P5 band instruments. We have created ad hoc scalings using the remaining, higher energy P6 and P7 channels to provide monitoring and alerts and are studying more long-term solutions. For details about science interruption due to the solar activity, please see ACE Data Plot Page.

• The Mean Detrended CTI

  Observations with cold radiator temperature deviation larger than 0.5 C
  from the nominal value of -127.92905 C are dropped (after DOM 200).
  
  
  Mean CTI observed when FPT~ -119 C and no testing modes (Squeegy, cuckoo, etc.) (average of 4 nodes per chip).
  CTI's are computed for Mn K alpha, and defined as slope/intercept x10^4 of row # vs ADU.
  Data file here
  

  
  
  CTI Slope (after DOM 200)

  
  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: Unit is cti/day from this month report.

  We are using 10 period moving averages to show trends of peak temperatures and peak widths. Note, the gaps in the width plot are due to missing/corrupted data.

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

  

• Focus
  
  We plot the width of the zero order streak of ACIS/HETG observations and the width of the zero order image for HRC/LETG observations of point sources. No significant defocusing trend is seen at this time. See Gratings Focus pages.
  
  
  

• Gratings Resolving Power

  We plot E/dE vs. E for fits to detected lines with fwhm_error/fwhm less than 0.1 for the plus and minus arms of HEG, MEG, and LEG. Also shown are conservative (dotted line) and optimistic (dashed line) pre-launch resolving power expectations.

ACA Trending

Gyro Bias Drift

Plotted below are radiation zone timing plots based on the following definitions of radiation zone:
RADZONE - Ephin levels (in any of the E1300,P4GM,P41GM channels) are more than 1/3 of RADMON safing thresholds.
RADMON - Radmon is disabled for radiation zone (as commanded based on OFLS model, for comparison with actual radiation levels).
PERIGEE - Time of closest earth approach (for comparison).
