1 2009-08-04 Tue 07:22 Updated startup schedule
Reminder there will not be a BTeam meeting this week. We will meet next
week. At Steve's Monday 1:30 meeting the remaining SAD work was
discussed. There are a few tasks that have an impact on Beam activities,
specifically C50-9 installation. As such here is the new schedule.
* Startup items
o C50-9 work implies the NL will be in restricted access
during weekdays up to Aug 13th. This will constrained the
Inj work to either 500keV or Swing/Owl shifts.
o Make sure Yves has enough time to perform measurements,
analysis and configuration changes.
o Tief needs a shift of RF on (no beam) to move the MO around
to examine the range of the tuners (12 GeV test)
o Emax's need to be determined for NL05, NL10, SL17, SL18
o NL05, NL10, SL17 & SL18 need to have parasitic Q
measurements performed once Emax's have been determined and
RF is stable.
o Once tune beam is in the BSY, BSY harps need to be checked
o tune beam to BSY, and BSY harps work: Perform BSY ?, TWISS
measurements and matching

2 2009-07-29 Wed Agenda--Notes
* Close out of the Summer Sad
o Gun status SOURCE
+ Inverted gun is producing electrons!!!
+ Conditioned to 110kV without any problems
+ Presently operating at 100kV
+ Preliminary lifetime of 70C!!!!
+ Preliminary injector setup by Reza -- found bumps in
0L04 and 0R03? regions. These are not new, but what is
the cause? Some of these bumps are 4mm!
o HKS status Spata
Mike is at the beach for the remainder of the week. HKS
installation is nearing the end. Lots of work on the
diagnostics, final hookups and checkout. Should be able to
complete the work as per the schedule.
o Hardware Status Lauze
Ron is also on vacation.
* Startup Plans
o Quick review of the schedule Arne
o Gun/Injector plans SOURCE
+ 2009-07-30 Thu More lifetime studies, beam on 8am to 11pm
+ 2009-07-31 Fri Laser table orientation for Parity
personnel. Inj open.
+ 2009-08-03 Mon-- 2009-08-05 Wed Parity alignment on
the laser table.
+ 2009-08-05 Wed Parity Beam characterization up to
500kV. Yves might be involved with this.
+ 2009-08-05 Wed PSS certification of Injector
+ 2009-08-06 Thu Reza start full injector setup and
finalization
+ 2009-08-07 Fri Reza complete Injector setup

start machine setup.
o Machine Restoration All
+ Other items
# Before beam is restored, but after EES has RF
up, Tief needs an eight period to perform some
studies on how far the Master Oscillator can be
changed and keep the cavities under control.
+ 7.5% unbalanced
A discussion as to the best approach to get to the
desired setup of 5.76 GeV with a 7.5% unbalanced
configuration.
# Plan A
* JB has created a high energy MST file from
the 6.07 GeV test in June.
* Use this file to scale to 5.76 GeV, balanced.
* Spin up 5.76 balanced and check out systems
* Go unbalanced from here
# Plan B
* Restore 5.97 GeV configuration from June09
* Check out the hardware
* Scale down to the 5.76 GeV 7.5% unbalance
configuration
# Decision
Plan B
+ Strawman, all dates tentative
# 2009-08-10 Mon RECO starts (the SAD calendar has
Aug-12, but it should start earlier so that it
is completed by Friday.
# 2009-08-10 Mon OPS 24-7
# 2009-08-10 Mon Injector setup completed?
# 2009-08-10 Mon Yves parity measurements in Injector
# 2009-08-10 Mon-- 2009-08-14 Fri EES RECO process

needed.
# 2009-08-14 Fri Tief Rf test

# 2009-08-17 Mon Start 7.5% unbalanced 5.76 GeV setup
# 2009-08-18 Tue Finish unbalanced setup.
# 2009-08-18 Tue-- 2009-08-19 Wed BSY ? and TWISS

* Parity quality
# 2009-08-21 Fri Resumption of physics
+ Other items
# Start up plan
Yan with assistance from Jay and everyone else
will construct the startup plan (plan B).
# Q measurements
Some zones were cycled during the down. These
zones should have Q measurements performed
during the week 2009-08-10 Mon-- 2009-08-14 Fri
# C50-9 commissioning
Time for C50-9 to start commissioning should be
carved out if restoration goes smoothly and the
halls are late.
# Optics on Call
JB will has populated the schedule. Please
confirm that you are available during the week
assigned.
# No meeting next week.
