High School Tour group and the PMC
There was a tour today of 40 high school kids.
I warned them that the lasers could burn out their
, that the vacuum could suck them through the viewports like tubes of spaghetti and that the
high voltage amps would fry their hair off.
One of them was taking a picture of the SOS in the flow bench and another one was whispering what
a dumb idea it was to leave a sensitive clean optic out where people might breathe on it. I told
one them to cover his mouth. The other one asked what was the glass block behind the SOS.
It was a spare PMC! s/n 00-2677 with a 279 nF capacitance PZT
. I guess that this is the one that
Go brought from MIT and then left here. So we don't have to take the one away from Bridge in the
35 W laser lab.
We can swap this one in in the morning while the FSS people work on the reference cavity
alignment. Please email me if you object to this operation.
