Ole Brandt, PhD student at DESY, recieved a PIER travel grant and went to Heidelberg to work with the "Kirchhoff Institute für Physik" (KIP). Here is his report.

PIER funded my six week stay in Heidelberg during which I was able to work together with the Kirchhoff Institut fuer Phrysik (KIP).

My PhD thesis includes the calibration and the commissioning of an Endoscopic Time of Flight Positron Emission Tomograph with Ultra Sound (EndoToFPET-US).
The EndoToFPET detector is build within a cooperation of several Universities and research facilities in Europe. The goal of this project is to build a fast (~250 ps coincidence time resolution) high resolution PET detector for prostate examination.
One part of the detector, namely the plate which consists of 4096 LYSO scintillator crystals glued to SiPMs, is currently at the University of Heidelberg. Therefore it was crucial for the development of my PhD thesis that I go to Heidelberg and work directly on the detector.

In my time there I was able to work with the people that have the most expertise in regards to the analog readout of the single channels and working with the plate itself.
We were able to perform the first measurements with the plate in the state it will most likely be used in the end. All the required slow control, including temperature monitoring, power consumption and cooling have been implemented in the existing software. Also the energy calibration of all the 4096 channels was finished and we were able to start with the most crucial part, the timing calibration.
The best coincidence time resolution achieved so far is 233 ps and we are optimistic to reach the overall goal of 250 ps for the whole plate.

For me personally the trip to Heidelberg was very successful in terms of progressing with my PhD project as well as the EndoToFPET-US project itself. Furthermore I was able to increase my knowledge of the electronics and the software of the detector.

Altogether it was a very productive and enjoyable stay, which was possible due to PIERs funding, thanks!
