Calibration (mean sdd4)


Mean fitting results are shown on below figures. A point of a figure is a fitted value of one run part. One run part corresponds to about 1 shift (4 runs) except for part 5. The red line is the fit value of the histogram summed up all parts.

The correction parameters ev2ch [eV/ch] and intercept [eV] are calculated from two means (Ti Kα1 and Ni Kα1) and their referential energies (4510.84 eV and 7478.15 eV). These parameters are not minimized in fitting directly but included to fix other X-rays means.

“ out ” means successive approximation (comparator) type PH-ADC
“ outw ” means Wilkinson type PH-ADC
