Updated H1QUADTST Foton File & EPICs Records, Open Light Current Values for QUAD06
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 In addition, the OSEMINF and DAMP filter banks were sorely out of date.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.

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:

OSEM  Open Light      Compensation    Compensation
      Current [ct]      Gain [ ]       Offset [ct]
R0LF    29804            1.007           -14902

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
