Minimum ellipse emittance analysis with SCUBEEx code

Results of the first beam emittance measurements obtained at the SARAF 20 keV/u protons and deuterons low energy beam transport line were analyzed using the SCUBEEx code from SNS. In most of the measurements the code provides with robust emittance evaluation. However significant problems were encountered in the special cases of low currents beams. We found that use of the minimum ellipse rather than RMS ellipse as a SCUBEEx filter ellipse resulted in significant improvement in these cases.
