hi Yi,
This looks indeed quite good I think. Thank you for documenting it.
Sincerely,

Gerard

Hi Gerard and all,

We have a look over the mechanical structure and the hybrid (v2.2). We believe the current design should be fine.
Please find some pictures in the following link: STAR_FST_MS_Pic_20191108.pdf <https://drupal.star.bnl.gov/STAR/system/files/STAR_FST_MS_Pic_20191108.pdf>

Our T-board doesn't have the male connector on it, but the space should be sufficient.

Cheers,
Yi

Hi Zhenyu,
        I'll try to look over all the various things I was supposed to
have
looked over
by the time of the meeting.
        In meanwhile, let me again ask if possible we can see a few
pictures
documenting that things really fit w/ the hybrid to T-board connectors
when
mounted (or simulated mounted) on the mechanical structure, I think this
would
be wise we see this before the v2.2 hybrid production. Of course if it is
impossible to check this at this time deciding to proceed anyway may be
necessary.
        Similarly I think it would be advisable we get pedestals out of
one
of the
existing hybrids if possible before ordering v2.2, but if that is
infeasible I
guess it is a small risk.
