Hi Richard,<br>
<br>
You proposed an architecture that employed a built-in solution for
power and bias supplies, thus your flexibility to control every SiPM
via DACs. Your internal power sources should meet FCC Class B for
EMI or better. These should already be part of your design and
procurement as there are no other budget items in our accounts. I
would be happy to review your specs and provide a recommendation.<br>
<br>
Best regards,<br>
Fernando<br>

<div>What do you propose for the Vbias and low voltage supplies
for the microscope? One idea would be to replicate what you
are using for the pair spectrometer. Another idea would be to
go out and buy something different and unique to our system.
I would be willing to go with either, and appreciate your
recommendation.</div>

Correct, no MPODs needed in the tagger hall.<br>

<div>Hi Richard, <br>
<br>
here is a link to the Wiener MPOD boards that are
used <br>
for the low voltages for BCAL SiPM boards and the
drift chamber <br>
preamp boards. <br>

I believe Fernando uses flavors of MPV 8008 and
MPV 8030 boards. <br>
<br>
To use these boards, one needs to put them into a
Wiener MPOD (full,mini,micro) crate: <br>

But as far as I know, there are no MPOD crates
that are planned for <br>
installation in the tagger hall, which can be a
problem. <br>

<div>I suggest that we go ahead and have our
regular biweekly working group meeting this
morning, even though there is a collaboration
meeting later on this week. There are things
we need to discuss that are not going to come
up at the collaboration meeting, and there may
be things that we need to raise at the
collaboration meeting that we should discuss
within the group first. I have put a draft
agenda in the usual place on the wiki. Please
modify as desired.</div>
