done
N
WCM
Roger L
test, new scopes, ethernet
done
Y

WCM in general tested: working properly, new scopes are working
- some modification in labview code still to be done
- connection with tape-sequencer to get timing for transition-mode
- action item: new calibration factors need to be set (with beam!)

test application
n.a.
Y

scope installed, connected to eathernet, data up-load time: approx. 2.5 min.
action items:
- locate hybrids, install
- finish cabling, matching, trigger cables
- OR box for blue/yellow triggers
- ADO design (pet page), for day 1: labview
- run analysis code on scope (likely with beam)

test, check out
Pete
Y

- BTF application checked and operational
to do:
- Brho correction during the ramp
- feed forward application
- desired tune/chrom appl. : what is this?
- BTF appl.: calculate and show tune distribution
- lock bit: verify interface to sequencer
- feedback on the ramp operational?
- injection stabilization?
