Hugh, Alvaro, TJ, Sheila

This afternoon Alvaro and TJ routed the fibers in HAM6 and Hugh installed the fiber feedthroughs.  Alvaro and I used the 532 nm (eye safe) fiber laser to check the transmission.  We measured 5.7 mW out of the fiber laser, 5mW out of the 532nm collimator and 3mW out of the CLF/seed collimator.  The fiber laser power might have been fluctuating during our measurements, but the fibers are working.

The feedthrough labeled SN8 is on the flange D4-2 connected to the fiber (SN..) which goes to the 532nm pump path. Feedthrough SN9 is on the flange D4-3, inside the chamber it is connected to fiber SN _ which goes to the collimator for the seed/clf path.  

This alog will be updated in the morning with the fiber serial numbers, and after I double check that I have the flange numbers correct.
