Here is the agenda for this week's meeting, pending planned Mott and
low-current stripline BPM
<br>
studies tomorrow. I will be out this Tuesday/Wednesday and Mike
Spata will chair the meeting.

Rich Wright reports that they looked again and there was
some activity.
Could have been deferred software update. Needs further
investigation,
no correlation between 0R04 MPS trips and diagnostic BLM
readings. Could
be a busted diode.

<p><a href="http://cebaf.jlab.org/atlis/task/10708">ATLis
10708</a>: Continued optics evaluation of machine,
particularly Arc7.
Done Tue 2011-04-05 <a
href="https://cebaf.jlab.org/elog/elog_item.php?elog_id=1577866">e1577866</a>,
included LOCO measurements and various
RayTrace measurements from Ryan. Two RayTrace sets, one
baseline and one
in support of LOCO, measuring with various quad settings
early in transport.
Some occasional beam loss problems. Yves is presently
analyzing data for LOCO;
Ryan is presently analyzing data for RayTrace. Acquired data
Tue 2011-04-26
for Arc 4/6 baseline before 6 month SAD H-steel magnet
retrofit.

bunch length measurements with HV gun: Reza (4h)</h4>
<p><a href="http://cebaf.jlab.org/atlis/task/11129">ATLis
11129</a>: ~2h in injector to test new settings for bunch
length measurement
tool at 130 kV. If this works, we'll have a reliable bunch
length tool for
October startup. Done 2011-04-28. Required some IOC reboots.
Script
improved, including prebuncher control and clean backout.

current (~10nA),
single-pass beam to BSY, stripline with new electronics to
establish low-current
threshold. Musson reports this item is not complete and can
use a little more
time. He's available on Tue 2011-05-03 when he is already in
for BFM above.
