HAM6 septum accelerometer installed

G. Moreno, T. Sadecki

The accelerometer and mount were installed on the HAM6 septum viewport.  See attached photos for the serial number of the installed accelerometer.  The accelerometer was plugged into the plug labeled 'B' on the octopus cable (interestingly, there was no plug labeled 'A', just 'B' though 'I').  The DB25 end of the octopus cable was NOT connected to the feedthru since other accelerometers are to be installed on the table at a later date, requiring that SEI lace the cable down the ISI.  

In the last photo (DSCN0142), one can see (although not that clearly) that the hex head of the accelerometer mounting screw has the "curly shavings" from the hex head stamping process still intact.  I recall these being a subject of concern during aLIGO install, so wanted to bring it up.  This accelerometer is in the segregated HAM6 volume and has presumably passed an RGA scan, so perhaps there is no issue here.
