Weekly Lab Report:
Using the 10kHz laser downtime to our advantage, the two rackable Environmental Control Units were taken down from above the optical table, to a rack has been postioned next to the table. As installed , checking the dessicant colour and replacing the cannisters as required was a inconvenient task, increasing wear and tear on the connecting lines
.
Replacement parts have been tested for the Pockels Cell Driver(PCD), with the revelation that electronic components from two different sources, with the same number stamped on them, and with the same spec sheet data, showed significantly different behaviour under load! A new order has been placed to source the parts from the same manufacturer as used in the PCD.
I walked the new PhD student through the chiller water replacement in one chiller, along with the coolant in the chiller for the 1kHz laser.
The new student got a mild shock off one of the optical talbes and got shocks off another one. After shutting all the equipment down (after powering up, following an RCD test), initial tests led to the closing of the lab and subsequently closing of the building. Further tests last Friday isioated a possible cause with further work the following week.
My work was focussed again on the paper which I need to complete a second draft of, early this week. I also produced a collection of presentation slides (using the beamer class) documenting internal photos our our FTI apparatus, along with some of the repair work done over the past months.
