Subject: Re: Hall D target

If possible, it would be nice to keep the cryotarget
"free standing" so that it can be removed for
maintenace/repairs without disconnecting alot of
detector electronics. It would also be convienent
to be able to replace the scattering chamber windows
without disassembling a detector. If you do mount
detectors on the cryotarget OVC then some thought
will have to be given to alignment.
