-== Collaboration meeting ==
-- The agenda is finalized: three talks from Mike, Simon and Sergey.
 == NIM papers ==
-- Mike demonstrated the nice features of the new ShareLaTex tool, other than that no recent progress with the papers.
+- As Naomi proposed: Beni will write the Introduction and the Conclusions. Naomi, Mike,Simon will work out everything in between. Curtis will proofread the paper. Naomi wants to use the "old" svn system working on one file (section) at a time without interfering with somebody else.
+- Lubomir is working on the VCI contribution (4 pages in NIM) to be submitted by middle of March.
-== Run Readiness ==
+== Run Status ==
-- Mike showed his latest results on the CDC performance. The efficiency vs drift distance is now flat (at a level of 90-92%) and dropping at the end due to the tube deformation, i.e. in some places the maximum drift distance is shorter. Eugene: why the efficiency is relatively low; this is with cosmics and Mike has to check all the cuts. Mike discussed also other efficiency plots as function of delta, the tube deformation parameter.
+-
 - CDC is now at 2100V. The HV scan will start from 2125V down with a step of 25V; the end of the plateau is at 2075V (Naomi).
