[Halld-tagger] Fwd: RE: goniometer quote and design

Thu Mar 8 09:14:10 EST 2012

Hi Ken,
Thanks for taking care of this, It's great that Newport is moving 
forward with this.
Does this meet our specs for angular resolution though?
As I remember, we specified two high resolution rotational stages
with 0.0002 deg, and one 340deg-range stage with 0.01 deg resolution.
The list in your message includes two wide-range stages and one
higher precision 45deg stage, but which has only ~17 microrad resolution.
 From looking at their stages, it looks like BGS80PP  type of stages would
match our resolution specs, but if they had vacuum compatibility options
and load capacity. On their web site they say that they can provide the
vacuum-compatible stages if it is not specified on their page.

As for the controller, we bough one similar to what is mentioned there
for controlling other motors in the hall, but with 8 axis, XPS-C8, and 
soon we
will start learning how to include it into our slow controls.
Hovanes.
