Abstract

The development and calibration of eROSITA mirror modules is supported by continuous measurements at the X-ray test facility PANTER. To obtain comparable measurement results after each new integration robust alignment procedures are needed to place the mirror module on the optical axis.

Here we present the different methods that we use to align eROSITA like mirror modules. One method uses the symmetry of single reflection images, another one is based on a symmetry of the intensity distribution, and the last one on the symmetry of the half energy width (HEW).
