> Below please find the minutes for today's meeting:
>
> *GEM Conceptual Design:*
> Eugene will schedule a meeting between Nilanga and Bob next Monday for the
> GEM conceptual design
> GEM Conceptual design:
> A box of helium-4 with two GEMs attached to the front/back surfaces,
> respectively
> GEM with helium as the working gas (it's still a preliminary idea)
>
> *HyCal Electronics:*
> HyCal needs about 7 crates of Flash ADCs. We might borrow these from CLAS
> but finding other resources is encouraged.
> Calibration needs  the revival of Hall B photon tagger (taking out focal
> plane detectors, finding old high voltage power supplies)
> It is encouraged to avoid the use of the photon tagger:
> Rough gain matching with cosmic rays and with adjusting scaling-constant
> in
> FADCs.
>
> *GEM Electronics:*
> SRS is not supported by CERN anymore.
> Around 200 APV chips left, need to spend 20k-30k to make them into cards.
> Might borrow some APV cards from SBS if not enough.
>
> *Review Meeting:*
> Prepare to answer the question: can the three experiments be scheduled
> back-to-back?
> Clear setup and plan required for the meeting: number of crystals, number
> of readout channels, using photon tagger or not, etc...
> Open discussions about these requirements in the next PRad2-DRad Weekly
> Meeting
>
> *Other:*
> Weizhi will give a talk at Chinese LQCD and promote the LQCD calculation
> regarding EM form factors (and charge/magnetic radii).
