<div class="moz-cite-prefix">Dear Shouyang, <br>
I won't be able to attend the meeting tomorrow so I quickly looked
at your slides <br>
and it looks like great progress were made with the apv25
electronics. I have a few suggestions that could help. <br>
<br>
- From the experience we had with this system at UVa I would
suggest that you check the connection between the APV25-FE and
flexible Panasonic-to-ZIF adapter. <br>
A bad connection of the ZIF to the FE card (which can happen very
easily) would lead to the spikes that you see in the bad event
that <br>
you referred too in your slides. It does not necessarily mean a
problem with the card. <br>
<br>
- And to make things even easier, you could try to get from
Evaristo or Paolo the newly produced APV25-FE cards with <br>
Panasonic connectors instead of ZIF connectors so you won't need
the flex adapter to connect to the chamber. <br>
A few prototypes of these cards had been produced earlier this
year by Paolo Musico to get rid of the flex-adapter that is source
of a lot of noise and <br>
bad connection problems. This way in your future tests and
commissioning of the APV25-MPD electronics you would not have to
worry abut bad connection. <br>
<br>
Hope that helps <br>
<br>
Kondo<br>

<div>Hi all,</div>
<div> </div>
<div>In this monthly GEM meeting, I will share my test
results about APV25 on my FEE board for GEM detector.
The title of my report is "Test of APV25 on FEE board
for GEM detector". I hope to discuss the test results
and my present work as well as my future work with you.</div>
<div>This is my first time to appear in this meeting,
please allow me to have a breif introduction to
myself. I am 李诚, Cheng Li, a student who works on the
design of GEM detector electronics. I am directed by
Professor Shubin Liu in FELab of modern physics
department of USTC. I am interested in the design of
electronics for particle detection, and I am glade to
talk with you on this meeting. Your advice and
suggestions are appreciated.</div>
<div> </div>
<div>Best regards</div>
<div>Cheng Li.</div>

<div>Hi all,</div>
<div> </div>
<div>Our November GEM monthly meeting will take
place next Wednesday, Nov. 27. There is a
particular matter we may want to talk about before
the meeting this time. That is the meeting time.
As we know, the US is back to the normal time.
Thus the time difference between Jlab and China is
now 13 hours instead of 12 hours previously. This
means our monthly meeting would start at 7:30am at
Jlab if we were to stick to the starting time of
8:30pm in China. I believe it's very unlikely that
7:30am would be an acceptable time for people at
JLab. So I would propose that we move our monthly
meeting back half an hour, namely, we start the
meeting at 8am at JLab or 9pm in China. Even
though 8am may be still a bit too early for people
at JLab, I am afraid we can't push the meeting
back any more. It would otherwise be too late for
people in China. Please speak up if the proposed
new meeting time won't work for you or if you have
any other ideas or suggestions on the meeting time
during "winter!</div>
<div> time".</div>
<div> </div>
<div>Last but not least (or even more important),
please let me know if there is anything you want
to show at the meeting. The skeleton agenda is at
