Cherenkov pictures

[Jeff Martin <jmartin@krl.caltech.edu>]

Hi guys,

I made a cherenkov pictures page:
http://www.krl.caltech.edu/~jmartin/g0/work/cherenkov/pics.html

There are a few pictures there of what we did with Lars' restrung wire 
frame this morning (tipping past vertical and looking for shifting of
aerogel).  These are pics #126, #127, #128, #129, #130.  This is a frame
strung with stainless wire with a weight supplying tension, and crimped
to hold in place.

Pics #107, #108, ..., #112 show the first attempt with fishing line.  A
lot of motion of aerogel was seen with that one, due to not much tension
in the line.  It was strung by simply running a long line around and
trying to keep as much tension as possible.

Not much shifting was observed for the new frame, and we can certainly run
in the vertical position (box on its side) at TRIUMF in December.  Lars is
considerably more confident with this frame.  Lars will try to do another
measurement of light yield before we disassemble for shipping.
