Dear All

See the e-mail below from Valery.  I am still waiting to hear from Sergey
about glass availability.

Dear Alex,

I found one Russian group that has on site 64
radiation-hard lead glass TF-101. This group is going
to use it in there own new setup. However they have plan to
put PbWO4 crystals in the central part of the calorimeter.
So in 5-6 years you can probably get the lead glass.

It seams for me that the Russian company that made lead glass
for us cannot do it anymore. The connection with this company was lost
10 years ago. But I am still trying to get more info about it.

By the way, you can probably consider to use PbWO4 for your 
calorimeter as well.
PRIMEX installed about 1000 crystals (2x2 cm) in the calorimeter.

Best regards,
Valery
