Scienta R3000: non-linear intensity scale correction

R3000 XPS Intensity scale calibration, Angular Modes, BACH, May 2015

Note: All calibration curves were done with detector area set to 640x384 px2, where 640px corresponds to full x (energy) scale, 384px to Y-(angular) scale between 53 and 436px.

Fixed Mode (Calibration → Voltages...→ Area)





Swept Mode




Graphs in higher resolution.

Approximate relation between intensity in swept mode and fixed mode (full detector range):

SES, Igor Pro:
Cps = C / n/ StepTime                   (1)
where,
Cps = couts per second in fixed mode ( approximately what we would see in Calibration → Voltages →Area)
C= counts in spectrum point acquired in swept angular mode
n = number of sweeps

KolXPD , if Io reading is ON and txt file was imported. If ibw file was opened accidently, use formula 1):
Cps = C * Io *N                                (2)
N = Number of steps = 0.124*PassEnergy/EnergyStep
