There was a tour today of 40 high school kids. I warned them that the lasers could burn out their
eyes, 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. |
