Hi Michele! -did you go in steps from 10 to 40 C? did you monitor drifts while doing that? has the energy range, where you do not observe problems, changed? In fact I was not planning to do that cause 40ºC seems to be the mono’s basal temperature. In addition, I operated n

Hey Andrew! Thanks for answering! Does someone have experience in minimize energy instabilities in beamlines? Are you sure it's an energy instability and not an intensity one? It's quite rare to see energy instabilities from a well calibrated monochromator. All monochromators should be in a clos
