Conclusions-Action Items:


1) It looks like we will be able to perform regularly and reliably the 
measurement of beam sent back from the Tevatron during reverse injection
cycles with the MI flying wires. Dean checked that data is being collected
now during reverse proton injections. Jim will check on how the data look 
like and after Tom lets us know what is the "offset" of the corresponding 
devices Vaia will introduce the emittances in SDA in the "eject protons" case.


2) More work is needed to make the Main Injector IPM data more easily usable 
by the Systems people and more easily comparable with FW measurements. 
The IPM devices have to go into ACNET and later in SDA. 


3) TCPORT:
a) tcport was switched to Linux over the shutdown.
The ported version was restructured a bit from the VMS version.
b) Its basic function was OK, but it turned out to be not
robust against systems connecting/disconnecting.
It turned out to be easy to make it fail with a test program.
c) It was restructured again, and a test version cannot
be made to fail like the current version. It is ready
to install, and the plan is to do that on Nov. 7.
It seems to work OK now.


4) Several modifications/improvements were implemented in the MI DCCTs and a 
new DCCT system (Bergoz) was installed for the Recycler. The new RR DCCT
has undergone several evaluation, calibration and frequency response tests.
The effect the MI ramp has on its response and a Recycler bunch length
dependence are under investigation. 
 

5) The original plans for testing the improved Main Injector longitudinal 
emittance algorithm (similar to the Tevatron algorithm), had to be modified
and some more testing time is needed.


6) There is an alarm now on Sync Lite and on TeV SBD everytime the TCPORT
list stops updating. Randy plans to ask the Tevatron people to inform the
operations crew on how to handle such alarms.



Our next meeting is scheduled for December 5, 2007.
