Typical definitions of 26ID scan detector channels

Detector Channel number EPICS Process variable Description
D01 26idsclr1:scaler1.S1 I0 - Integrated Ion chamber current after NES slits (change current amplification via yellow SR570 tab on main beamline screen)
D02 26idcXMAP:mca5.R1 Bi - Fluorescence channel from outboard detector, summed ROI#1 - find and modify with MCA software from User Tools tab on main beamline screen
D03 26idcXMAP:mca5.R2 Ti - Fluorescence channel from outboard detector, summed ROI#2 - find and modify with MCA software from User Tools tab on main beamline screen
D04 26idcXMAP:mca5.R5 Fe - Fluorescence channel from outboard detector, summed ROI#5 - find and modify with MCA software from User Tools tab on main beamline screen
D05 26id:ccd.R01.Average Integrated Intensity/Num Pixels for CCD ROI#1 - ROI#1 defines the total active chip area to be saved, so this is the total CCD intensity per pixel
D06 26id:ccd.R02.Average Integrated Intensity/Num Pixels for CCD ROI#2 - usually tightly defined around the outgoing beam - Contrast here is related to diffracting volume
D07 26id:ccd.R02.XCentroid X center of mass of intensity in CCD ROI#2 - This is related to lattice strain and rotation in the diffraction plane, scales away from center of ROI2 with signal/dark current
D08 26id:ccd.R02.YCentroid Y center of mass of intensity in CCD ROI#2 - This is related to lattice rotation out of the diffraction plane, scales away from center of ROI2 with signal/dark current
D09 26idcDET:userCalc3.VAL R02.Average - R03.Average, Background subtracted average intensity - ROI#3 typically set around an unused area, this is useful for viewing scans in progress with low contrast
