Investigations On Algorithm Development For Non-Invasive Transverse Beam Emittance Measurements — •Ezgi Sunar¹, Adem Ates², Hendrik Hähnel³, and Ulrich Ratzinger⁴ — ¹IAP, Frankfurt, Germany — ²IAP, Frankfurt, Germany — ³IAP, Frankfurt, Germany — ⁴IAP, Frankfurt, Germany

A non-invasive diagnostic concept has recently been developed for the Frankfurt Neutron Source Experiment (FRANZ) at the Institute for Applied Physics (IAP) at Goethe University Frankfurt. The aim of this improvement is to compute transverse emittances by monitoring the beam induced rest gas fluorescence along the diagnostic box at the LEBT section of the FRANZ experiment. Because the special cameras are inserted into the vacuum and observing the beam along a 480mm path it is expected to measure the angle of divergence in a more precise way. An algorithm has been developed for these imaging and computing processes. It is based on extracting the width of the transverse intensity distribution of the beam at three different positions or by setting the solenoid magnetic field strength at three different values. The reliability test of the algorithm has been done with various simulated data in TraceWin and further progress for improving the algorithm is assumed. The preliminary results measured by the simulation data are showing a decent outcome consistently.
