[Tpe] Tungsten parts for TPE

[David Kashy]

Hi Larry,
To do a good job with collimation we will want to accurately align this 
device. I've got Pete looking at this.  When  will you guys have a study 
on the diameter desired.
I know you simulated 2.0cm what about 2.2 or  1.8 or other?

Thanks
Dave
