keyword=emiss resolutionGiven the fact that the scattering chamger cover and the spectrometer entrance cover were on last night after the He plume, there is some concern about the bad emiss resolution of the 3He 2-body break up peak. I checked to see whether this bad resolution is due to optics or raster. also the peak was at the wrong place.
It is mainly due to raster. (figure 1) , I corrected it by hand and also I made some optics corrections also. Emiss resolution comes to be about 3.5 MeV (FWHM). Given that we have to separate the 3-body peak about 7 MeV away, this data is fine.
