Gain factors from charge injection default and measured

gain	charge injection	current default	measured (ADU / keV)	2020-08-03 Gabriel (ADU / keV) - use as default
L	0.46	0.01	0.139	0.164
M	15.	0.3(3)	4.5	5.466
H	46.7	1	13.9	16.40

Gain factors default vs charge injection

...

gain from charge injection:

constants	Mean	RMS	RMS / MEAN
default	1117.7	62.72	0.05618
charge injection	1177.5	66.79	0.05672

Conclusion: in this test charge injection gainci constants do not improve gain factors comparing to default

Hi, Here are some good starting values for the ADC to keV conversion:

High gain: 132 ADU / 8.05 keV = 16.40 ADU/keV
Medium gain: 132 ADU / 8.05 keV / 3 = 5.466 ADU/keV
Low gain: 132 ADU / 8.05 keV / 100 = 0.164 ADU/keV

Of course, a gain calibration is preferable.
The same numbers work in both fixed and auto-ranging gain modes.
Thanks,
Gabriel

Hi, For the long integration time, I don't have a set of magic numbers, but this iterative procedure should yield optimal settings:

Cool the camera as low as possible, just a few degrees over the minimum temperature to allow temperature stabilization by the PID control loop (either the chiller PID for the large cameras, or the Peltier PID in the small cameras). Of course, the small cameras can be cooled much lower than the large ones.


Start with the default LCLS settings (I believe both AsicAcqWidth and R0toAcq are set to 100us by default)

0 AsicAcqWidth should be optimized for the experiment. With a very cold camera (e.g., < -15ºC) you could go to 5ms. A good starting value would be 1ms.

1 Set AsicAcqWidth to, e.g., 1 ms
2 Set R0toACQ time to 100us
3 Decrease frame rate until no frames are dropped
4 Set the X-ray source to a low flux (0.01-0.05 photons/pixel/frame?)
5 Try to get a uniform illumination
6 Repeat:
- Calibrate dark
- Take many frames and integrate them
- Look if the resulting image is uniform or has a strange sawtooth pattern over each ASIC
- If no, try reducing R0toACQ
- If yes, try increasing R0toAACQ
- Increase/decrease frame rate to the maximum frame rate that runs reliably (no dropped frames).
6 Until an optimum is found.

For an idea how the strange sawtooth pattern looks, you could try setting:
AsicAcqWidth = 1ms
 R0toAcq = 50us, or 20us.

Thanks,
Gabriel

Hi Philip, Chris, and Mikhail,

My apologies for not getting this to you sooner. 

Additional apologies in that the order we took the measurements in
is rotated from our "standard" and we were unable to set the origin
to zero. In the picture the XPP mounting bars on on the left side and
so this would be UP. 


A map of the sensor corners measurement ordering and the quad 
number locations is attached along with a picture of the setup. The
origin (not 0-0-0) is in the upper left of the picture.


Along with the Excel spreadsheet. 
Please ask questions as I know this can be confusing. 
Thanks,
Chris
