J. Kissel, T. Sadecki Travis has plugged in OSEMs to QUAD06 mounted to Mechanical Test Stand 1, read out by QUADTST, in the West Bay of the LVEA for the first time in many moons. After having re-compiled, re-installed, restarted the front end process a few days ago (see LHO aLOG 13833), the EPICs records ha not been restored. In addition, the OSEMINF and DAMP filter banks were sorely out of date. So, I BURT-restored the presumably very-old ${userapps}/release/sus/h1/burtfiles/h1susquadtst_safe.snap which restored all matrix elements correctly. I then installed the just-measured open light current values (recorded below for QUAD06). However, since the foton filters were all wrong, I took some time to copy the OSEMINF and DAMP filters from H1SUSITMY, turn them on correctly, checked that the matrices and COILOUTF gains are correct, and grabbed a new safe.snap. and committed both filter file and fase.snap. Travis will gather the OSEM serial numbers shortly and match them to there location installed below. OSEM Open Light Compensation Compensation Current [ct] Gain [ ] Offset [ct] M0F1 29723 1.009 -14862 M0F2 29212 1.027 -14606 M0F3 28998 1.035 -14499 M0LF 27100 1.107 -13550 M0RT 29422 1.020 -14711 M0SD 29032 1.033 -14516 R0F1 26949 1.113 -13474 R0F2 28436 1.055 -14218 R0F3 27950 1.073 -13975 R0LF 28311 1.060 -14156 R0RT 27786 1.080 -13893 R0SD 26947 1.113 -13474
Due to some shorting issue that occurred while swapping the R0 LF and RT BOSEMs, I had to swap out the R0 LF BOSEM. We recalculated and reloaded the offset and gain for this channel. The new values are:
And the corresponding serial numbers for all BOSEMs are:
M0F1 026
M0F2 195
M0F3 015
M0RT 102
M0LF 302
M0SD 294
R0F1 310
R0F2 292
R0F3 085
R0RT 029
R0LF 574
R0SD 437
