The project aims to develop a EUV/soft X-ray sensitive sCMOS camera suitable for high repetition rate imaging and spectroscopy as well as single photon detection. Therefore an existing CMOS camera platform will be optimized towards an EUV & soft X-ray sensitive sCMOS camera suitable for high-repetition-rate imaging or spectroscopy as well as single photon detection.

The successful candidate will have an enrolment for the doctoral degree at Freie Universität Berlin and will work in the R&D group at greateyes which consists of mechanical & electrical engineers as well as physicists and (embedded) software developers of multiple nationalities.

In addition to the scientific work in a stimulating, international and interdisciplinary environment, the ESR will gain profound knowledge in state-of-the-art, low noise electronics design (PCB design), photonic sensor as well as UHV technology. Both will open up many job opportunities in either public research laboratories involved, or in the high-tech industry not only limited to photonics.


Work Topics:

The project deals with the development & characterization of a new electronics and software platform for novel scientific CMOS cameras aimed to detect photons in the EUV & soft X-ray regime with outstanding performance. In particular, a detailed comparison of new sensor technologies with existing CCD detectors is crucial to understand the pros and cons of each technology.

The new hardware platform is to be redesigned towards handling the heavy data streams (1-100Gb/s range) involved in the read-out process of wafer-scale CMOS and pixel sensors at the high frame rates demanded by the applications. To further reduce the image acquisition time for high repetition rate experiments a FPGA based implementation of a flexible region of interest (ROI) read-out function will be crucial. An extension of the photon shot noise limited regime of the sensor towards the lowest possible charge levels will be beneficial for the detection of single photons. Therefore the platform electronics need to be optimized towards lowest possible read-out noise of the sensor.

Taking advantage of our partner network of national and international research institutes, universities and industrial partners in the field, prototypes of cameras featuring different sensor technologies will be characterized. In particular their performance depending on the energy range, photon flux, repetition rate, and other parameters are to be evaluated.
