After being provided with the open light counts for each BOSEM and AOSEM on MC2, gains and offsets were calculated and plugged into the medm screen OSEM INPUT filters for M1, M2 and M3. 

M1 BOSEMs
Top 1 (T1), sn = 092, OL = 27702.4, offset = -13851, gain = 1.083
Top 2 (T2), sn = 043, OL = 22923.7, offset = -11462, gain = 1.309
Top 3 (T3), sn = 030, OL = 28098.7, offset = -14049, gain = 1.068
Left (LF) , sn = 023, OL = 26766.2, offset = -13383, gain = 1.121
Right (RT), sn = 086, OL = 27693.4, offset = -13847, gain = 1.083
Side (SD) , sn = 613, OL = 30169.8, offset = -15085, gain = 0.994

M2 AOSEMs
Upper Left (UL) , sn = 307, OL = 24825, offset = -12413, gain =	1.208
Lower Left (LL) , sn = 474, OL = 24060, offset = -12030, gain =	1.247
Upper Right (UR), sn = 439, OL = 24304, offset = -12152, gain =	1.234
Lower Right (LR), sn = 305, OL = 25954, offset = -12977, gain =	1.156

M3 AOSEMs
Upper Left (UL) , sn = 207, OL = 24822, offset = -12411, gain =	1.209
Lower Left (LL)	, sn = 311, OL = 23630, offset = -11815, gain =	1.270
Upper Right (UR), sn = 446, OL = 26177, offset = -13089, gain =	1.146
Lower Right (LR), sn = 188, OL = 16687, offset = -8344 , gain =	1.798

Now that these OSEM gains and offsets have been applied, each OSEM can be centred/aligned.

Relevant DQ channels needed to be made available for the new x1sushxts05 model. Therefore the x1sushxts05.ini file has been edited to include the following channels (note that the original file was backed-up with the file name x1sushxts05_bak.ini):-  

X1:SUS-HXTS_M1_OSEMINF_T1_OUT_DQ

The framebuilder was restarted using the following commands:-

telnet tripleteststand 8087

shutdown

Now that all the above channels are available, it should enable transfer functions and power spectra to be taken. 

[Stuart A, Jeff B, Betsy B]

Thanks for the efforts of those on-site at LHO, who have suspended MC2 (HSTS) and aligned BOSEMs/AOSEMs, which has enabled the first set of transfer functions to be taken this evening, using the alternative x1sushxts05 model on the triple test stand.

Prior to taking transfer functions it was necessary to conduct some pre-flight checks of the digital system, watchdogs, filters, and verify correct sensor and actuator signs.

Transfer functions have been carried out for all degrees of freedom with damping loops OFF. These show good agreement with the model, can be found below.

However, these TFs need to be compared with results from previous phases (plots pending), and M1, M2, M3, power spectra taken, before MC2 can complete Phase 1b testing. 

All data, scripts and plots generated have been committed to the SUS svn as of this entry.

Finally, a BURT snapshot has been taken of the functioning x1sushxts05 environment (20120614_x1sushxts05_MC2.snap).
