Need help? / Microscope for X-ray imaging
« Last post by cozkan on September 03, 2021, 12:05:08 PM »Trying to image a focussed beam on a scintillator (5um Ce:YAG on YAG substrate) at 11keV (photon energy).
NA of the microscope objective used is 0.65 but cannot seem to measure a beam spot size ons cintilaltor smaller than 5um. The expected spot size is 2.5um.
Is this due to the scintillator? Do I need a thinner one? is this because of the higher penetration depth at 11keV? Is it because this is a focussed beam?
Does anyone have any similar experience?
Many thanks in advance
