Cons Gattuso   Studies and Operations Progress

Horizontal apertures scans are complete.  Some corrector channels need
additional voltage to provide the current range which the magnets can
support.  At present some correctors cannot be driven above about 5.5
A or so, limiting the range of the scans involved.  Studiers have
improved their habits and Page D1 saves have been taken at the end of
shifts.  The problem with events for $26 (MI Rampdown) appearing in
the ramp tables of some RR correctors has been examined.  It is
associated with a switch setting in the 453 ramp card setup which
needed (needs?) to be checked out for the more recently installed RR
corrector cards.  It may be that only one 453 was in that mode.  Dave
Capista notes that the alarms page is set up so that each corrector in
the Main Injector will create an alarm if that bit is not enabled and
the inverse check and alarm could be created for each Recycler
corrector channel.

Announcements/Discussion

The systems for corrector programming to change the RR energy
(momentum) with the dipole correctors is now complete and checked out.
Software is complete but implementation is not final.  PBar transfers
will replace proton studies as the regular activity beginning next
Monday, December 16.
