| Abstract |
A non-destructive CVD diamond X-ray beam imaging monitor has been developed for synchrotron beamlines. The device can be permanently installed in the X-ray beam path and is capable of transmissively imaging the beam profile at 100 frames per second. The response of this transmissive detector at this imaging rate is compared to synchronously acquired images using a destructive fluorescent screen. It is shown that beam position, size, and intensity measurements can be obtained with minimal disturbance to the transmitted X-ray beam. This functionality is beneficial to synchrotron beamlines as it enables them to monitor the X-ray beam focal size and position in real-time, during user experiments. This is a key enabling technology that would enable live beam size feedback, keeping the beamline’s focusing optics optimised at all times. Ground vibrations (10-20Hz) can cause movement of focusing optics and beamline mirrors, which disturb the X-ray beam and reduce the ultimate quality of the sample-point beam. This instrument can detect this beam motion, enabling the source to be more easily determined and mitigations to be put in place.
