In 2017 an x-ray camera for the pnCCD detector at European XFEL was sourced from PNSensor GmbH. Now one pnCCD module of the x-ray camera needs to be replaced. Another pnCCD module needs to be refurbished. For technical reasons the contract for these components can only be awarded to PNSensor GmbH because only PNSensor has the required expertise and knowhow.
