       Summary
     -----------------------
0. Slides are at the agenda site:
http://ilcagenda.linearcollider.org/conferenceDisplay.py?confId=2752

1. News.
-Ron chaired this meeting since Jan just had test-beam duties at CERN
today.
-See the agdena site for upcoming meetings.  It was decided to have the
next WP phonemeeting in 2 weeks from today.  Topics for the LCTPC meeting
and the Jan's tracking session in Warsaw are requested.
-Ties reported that the Si detectors will not be ready until late fall.
RS said that there will still be plenty of trouble-shooting to do at the
start of commissioning.

2. LP cosmic trigger.
-Paul reported that the trigger preparations at Saclay and on the
preparationfor the Micromegas panels for the LP; see the slides at the
agenda site.  The handling tool for mounting was devised in agreement with
Akira.

3. LP laser, endcap and fieldcage.

Laser:
-----
-Alexei will exchange information offline with Peter about
mirror-bundle+shielding mounting.

Endcap:
-------
-Dan reported that production is proceeding well, see
http://www.lepp.cornell.edu/~dpp/linear_collider/LargePrototype.html
Dan will test each endplate panel-position with dummies, and this
may delay delivery to the groups by a couple of weeks. Dan will provide
the o-rings.

Fieldcage:
----------
-Peter showed slides on the fieldcage production (see the agenda site).
In answer to a question by Dan, the mandrel is collapsable.
-Alexei reported that Howard Wieman reminded that the resistor chains
must be shielded to the driftvolume.

4. LP1 electronics.
-Leif updated the financial situation on the agenda site.  We are going
for the 10000 Channels, and money from Desy will probably cover the
missing funds from Carleton. Sasha said that Rostock may have additional
funds also.  Leif will contact Lucie (Linsen) to organize the CERN
involvement.
-Leif showed the fruits of the trouble shooting of the new electronics:
Plot 1 on the agenda site gives the situation after the meeting a few
weeks ago, and plot 2 is the situation now; the improvement is impressive.
Plot 3 shows signals from Lund's small test TPC.

5. AOB.

-Dan requested that the NSF be acknowledged on the IEEE contributions.

-Next meeting:
 WP58 phonemeeting 4 June 2008
