2) Recycler Dampers

4) Status of the "Store Checker"
Mary Convery

Conclusions-Action Items:


1) The code containing the new emittance algorithm for the Main injector
is stable.  We will try to understand why there is a few % offset
between MI 150 GeV and TeV 150 GeV emittances for both protons and pbars. 
(MI emittance bigger). There is some "ringing" as well that we are trying to 
understand better. This could have been there before but we are more sensitive
now since we are looking at 95% emittances.  

The comparison betweeen old and new MI emittances looks reasonable.
The plan is that we will switch to the new emittances as the default ones
(numbers that appear in the shotscrapbooks) in June.  


2) The Recycler Transverse VME Dampers are back in operation since May 14, 2008,
after the cause for the RF PLL losing lock was identified and fixed.  


3) MI Flying Wire tests: Several tests are in progress now for the MI Flying Wires
(tension, vibration, etc.)
While new forks are being assembled for the Main Injector some tests are being
performed with a Tevatron fork.  

If there is an access in June at MI, the expectation is that the vertical MI Flying 
wire could be probably reinstalled.  


4) MI IPM:

There is continuous progress in this project. We are in the commissioning/debuging
stage and the expectation is to have this project complete during the first couple 
weeks of June.


5) The criteria for "error reporting" for Flying Wires in the Storechecker package 
http://www-bd.fnal.gov/javaapplications/html_write/StoreChecker/
have been significantly improved. The plan is to improve the criteria in the remaining
devices in the list, as well as flag some addional devices there (like the SBD).
E-mails are being sent with these error reports to some small list of colleagues.
If you want to have your name added to the list, please let Mary know. 




Our next meeting is scheduled for Wednesday, July 2, 2008.
In the mean time we are trying to see if we can possibly have a
TeV IPM report before that time, since Andreas will not be available
at the July meeting.
