Abstract: A novel X-ray Beam Position Monitor has been designed and implemented on the Multimode InfraRed Imaging And Microspectroscopy (MIRIAM) beamline at Diamond. Installed in the B22 Front End and using no optical elements except for filters, it provides sub-micrometre position sensitivity and sub-microradiant angular sensitivity to Bending Magnet source vertical movements. By sampling at 100 kHz frequency, Fast Fourier Transform analysis is continuously displayed and any periodic components in the Synchrotron Radiation emission are revealed within the exceptional bandwidth of 50 kHz. Long term source drift in position or angle are monitored and recorded every 0.5 seconds.
