Author: Jin-Seok Ko

The purpose of this run is (1) MSE viewing angles measurement
and (2) Investigation of aperture broadening effect by measuring the MSE
spectra in the He gas-filled torus without magnetic fields. We had 29
useful shots with a good beam performance (1 sec pulse, 50 keV). The
spectra were measured for 3 different MSE spatial channels.
