I am sure details will change but this is how it looks to me now:
A) No clas target, since the region I chamber will be on the
installation cart.
b) no start counter, see a)
c) carriages will not be in the installed position so work can proceed
on the region II and region III chambers.
d) if region I is on beam axis (while on the insertion cart) the
photon beam will be propagated through to the downstream devices
and rad-phi
All this means we should make the most out of the 12 hours of photon
beam we have during this electron beam run.
In order to finish the tagger commisioning, and photo-fission in
july we need to to understand the following issues:
if the forward carriage is retracted for DC repair can we trigger
on the master or?
Can region I reside on the installation cart and not obstruct the
photon beam??
Can the photo-fission experiment fit with region I sitting on the
installation cart??
