Dear Daniel, is this for a Bruker Diffractomete? If you have a choice, I would be surprise, because Bruker refused to offer a new D8 with an EIGER2R500 detector - they'd rather not sell their system, and we got a STOE Stadivari instead.
We've had a PhotonIII for about 1/2 year on our D8. It is more sensitive than its predecessors, but it still shows noise. When you are used to HPC detectors, it shows a lot of noise, although others are really happy with their PhotonIII. When we got the upgrade from PhotonII to PhotonIII, this was only a firmware upgrade, the very detector stayed installed on the system. However, the PhotonIII is of course fully integrated with the D8 system. The EIGER2 R500 that we have been using of 1/2a now, is not smoothly integrated, and requires probably a nerd like me to be really pleased with the D8+EIGER2 ;-) page 24 on my lecture note https://homepage.univie.ac.at/tim.gruene/teaching/chemcryst/pdfs/2023/tgruene_chemcryst_2023-v05.pdf is with the PhotonII (maybe PhotonIII, i.e. with firmware upgrade, I need to double-check), while p. 25 is from the EIGER2 R500 (about half the size of the PhotonII). The gain range determined by XDS is 0.97-1.3 for the PhotonII, for the EIGER2, it is 0.96-1.02, i.e. very close to 1.0. This is for CuKa, for MoKa, the gain with the EIGER2 is about 0.7. I could find a data set from the PhotonIII and process them with XDS to get comparable figure for MoKa, in case the info will be of interest for you. Feel free to ask more specific questions, or pass by for a visit in Vienna to take a look at the Eiger2 on D8 and Stadivari.
