As these studies mature they will hopefully spawn separate pages. For now, the rest of this page is for (1), the FHE trigger study.

Calorimeter autorange study for PS (T. Ylinen & J. Conrad)

Looking at reprocessed 4-range readout runs 700000700-700000750, provided by T. Reposeur, the performance of the autorange at PS was studied. The feature seen in a ion run at GSI could not be seen in this study. See attached presentation (ppt).

Calorimeter autorange study for SPS (T. Ylinen)

Looking at reprocessed 4-range readout runs 700001789, 700001791, 700001795, 700001799 and 700001801, the performance of the autorange at SPS was studied. The feature seen in a muon ion run at GSI could not be seen in this study either. See attached presentation (ppt).

1962-1970: FHE thr: 0.5 -2 GeV x= 603, y = 41, z = 1

The variables used areunmigrated-wiki-markup

CalReq\[tow\]\[lay\]\[end\]    (Trigger request send, TEM diagnostics) (SVAC tuple)

Wiki MarkupCalXtalFaceSignal\[tow\]\[lay\]\[log\]\[end\]    (Calibrated energy)

The maximum in each layer of CalXtalFaceSignal has been taken 

First results for run 700001952:

 max_layer(CalXTalFaceSignal) for layer 1 (h2_0) to 8 (h2_8).  Note the difference in x scale !!

 Image Added
 

 FHE trigger efficiency (as seen by the TEM diagnostics) for layer 1 - layer 8.
