Re: scintillators



Hi,
When we made the  light guides for mucap we sent the light guide 
strips out to bid.  I faintly recall "Acrylite GP" being the acrylic 
of choice.  I have attached PDF's of the chemical resistance and 
light transmitance values for Acrylite GP.

When cleaning acrylic strips we generally use ethanol.  If the 
acrylic was machined under stress then cleaning with ethanol will 
make the material "craze".

Brendon is correct about the gluing procedure.  Shoot the UV 
lamp/wand through the light guide.
