2. Introduction

During August 2020, a new pnCCD detector was delivered to European XFEL from PNSensor. The serial numbers for this detector are 205 (for top sensor) and 206 (for bottom sensor). It was commissioned from the \(11^{th}\) to the \(16^{th}\) of August. We could not obtain the calibration data during that week. Instead, the calibration data were acquired on August the \(20^{th}\) at 1.6 keV beam energy using aluminium fluorescence.

This report presents the summary of the results of a performance analysis of the new pnCCD commissioning and calibration data obtained in August 2020. An overview of the dark characterization, common mode characterization, CTI evaluation, gain calibration, and full well capacity determination for this detector is given in this document.
