DOE PEP-II Operations Review

2. OPS Review Topics
Does the program have adequate resources (i.e. manpower, funding, etc) allocated to carry out the plans?
Is laboratory management effectively tracking progress?

3. Topics Run Planning Run Operation PEP-II Performance Goals:
Less than 3 aborts per day
< 1 RF abort per day
< 1 radiation abort per day
< 1 “all other” abort per day
Uptime >> 90%.

4. PEP-II Scheduling PEP-II Accelerator Run Planning is done with:
Laboratory Director (J. Dorfan)
Particle and Particle-Astrophysics Directorate (P. Drell)
Assistant Director of PPA for Accelerator Systems (J. Seeman)
PEP-II Run Coordinator (U. Wienands)
BaBar Spokesman (D. MacFarlane)
BaBar Technical Coordinator (W. Wisniewski)
BaBar Run Coordinators (J. McKenna, G. Bonneaud )
Technical staff
Power Manager (G. Loew)
Operations Head (R. Erickson)
Spokespersons of other small experiments.

5. Scheduling Committee

6. Scheduling Committee Scheduling Committee members:
J. Seeman (Chair), R. Erickson, C. Field, J. Weisend, W. Wisniewski, R. Hettel, P. Pianetta, D. Schultz, R. M. Boyce
Meeting every few months as needed.
Propose running schedule to the Directorate
Provides power requirements versus month.

8. Over all PEP-II Down Schedule 2004-2010
2005 down: October 11-November 15
2006 down: August - November, 2006.
2007 down: September – November 2007
Every downtime is planned in great detail (See available handouts).

11. PEP-II Task Force Structure to review risks
April 2006

12. Ongoing Accelerator Improvement Projects (AIP)
X-Y BPM upgrades
New HER Q5 vacuum chambers
New HER/LER Q2 chambers
HER-10 RF station
HER-11 RF station
HER power supply upgrade for higher tunes 2006
New HER Q4 vacuum chambers
NEW IR2 Q2 bellows
LER IR HOM absorber
HER IR HOM absorber
LER BPM monitor upgrade
LER new high power bellows
LER NEG vacuum chamber upgrade 2006
New Longitudinal feedback processor 2006
Cost of remaining AIP projects is about 7 M$ spread over two years.
PEP-II AIP expenditures from averaged about 5 M$ each year.

13. Projects reviews for Accelerator Division Hardware Projects
All projects for PEP-II this year!

14. Management: Reliability is important Reliability/Tuning Task Force: Mattison/Himel
Work more to reduce “aborts.”
Reduce “tuning time” after aborts or repair outage.
RF group is making very steady progress but have more to do to fix root causes.
ARTEMIS reporting system is a good recording tool.
PEP-II “tune” feedbacks could use improvements.
Upgrade dither feedbacks at the IP.
Area managers: Upgrade turn-on check lists.

37. PEP-II Conclusions
SLAC management has set luminosity goals and we track our progress against those goals.
Teams are in place to study PEP-II operations, accelerator physics, and to improve reliability methods and root causes.
Operators, engineering staff, technicians, and maintenance people are in place to carry out the PEP-II program.
We track carefully the abort rates and outages to improve reliability, uptime, and average luminosity.
Short term abort rate was high in December 2005 – March 2006 due to new vacuum related instabilities. Abort rates are much lower now that the vacuum repairs have been made.
Resources are adequate carry out the program.
