BooNE Meeting, January 15, Prebys 1 How are we doing? Best running Power loss (W) Protons (p/min) Energy Lost (W-min/p) Best running again ? Mysterious bad running

BooNE Meeting, January 15, Prebys 2 How far have we come? Time (s) 5E12 Before MiniBooNE Now (same scale!!) Energy Lost Charge Note less pronounced injection and transition losses

BooNE Meeting, January 15, Prebys 3 Last 4 Weeks - Detail Energy lost per proton Protons per pulse Protons to MB [p/hr] Mysterious dip

BooNE Meeting, January 15, Prebys 4 Related to Linac current? Linac Current Total Protons Energy Loss/proton

BooNE Meeting, January 15, Prebys 5 Christmas Klystron Woes  As of Dec. 1, we believed 800 MHz klystrons were not a worry.  Only two had failed  We had six spares  A few days before Christmas, the klystron in station one failed.  Three spares turned out to be bad  Tracked down to vacuum problem (and a flaw in our measurement technique).  Plan  Ralph Pasquinelli put in charge of investigating and acting  We think we understand the problem and will work with L3 to address it.  Current stock  One “good” spare (i.e. verified vacuum).  One good tube at lab G, which is being moved.  One gassy tube, which can probably be conditioned  One tube being rebuilt at L3. Delivered ??  One tube being sent back to be rebuilt (4-6 months).

BooNE Meeting, January 15, Prebys 6 Alignment in the Booster  Always been recognized as a problem  A little over a year ago, we started a vertical network of the entire Booster  Level run  4 survey points on each magnet (some a bit complicated)  (Mostly) completed during the shutdown. Data now in hand.  Some big problems!  Historical difficulties  Lack of priority!  Lack of a coherent plan, both on our part and alignment.  Inefficient use of downtime (response time issues).  Solution? What else – a task force.

BooNE Meeting, January 15, Prebys 7 Big Alignment Problems!

BooNE Meeting, January 15, Prebys 8 Alignment Plan  Peter Kasper put in charge of coordinating alignment on our end.  O’sheg made task manager on the AMG end.  Andrew Feld will be trained as a liaison.  Near term goals (ASAP as opportunities arise)  Complete vertical network (5-10% to be done or redone)  Develop a plan for vertical moves, including both “opportunities” and longer term requests.  Align RF cavities and other key elements to optical center of straights.  Longer term (aim to complete by next big shutdown)  Produce a “beam sheet” based on Sasha’s MAD file  Add non-magnetic elements  Complete network, including horizontal.

BooNE Meeting, January 15, Prebys 9 Collimators  Chose to wait until we were running “better than when we shutdown”.  This happened two weeks ago, so we were going to start last week.  Last week  Efficiency dropped.  Dave has asked us to wait to finish the 400 MeV line studies.  I’d like to start this week.  I’m working up a study plan.  Will do extinction studies as opportunity arises.  Working on beam motion control to allow cycle-dependent studies (Dave McGinnis’ suggestion).

BooNE Meeting, January 15, Prebys 10 Machine Summary (from McGinnis)  Proton Source  Linac Current Optimization Goal: More protons to MiniBoone Slightly lower Linac current points to better efficiency in Booster Counter-intuitive with past “thinking”  400 MeV Optimization Goal: More protons to MiniBoone Smaller beta functions for less beam loss in line Phase space matching for more efficient transfer into Booster Three lattice iterations were done over the weekend –Numerous problems identified. –Solution to problems relatively straight-forward in a 2-4 week time-scale

BooNE Meeting, January 15, Prebys 11 Machine Summary (McGinnis, cont’d)  Proton Source  Booster Collimator Goal: More protons to MiniBoone Key to the success of the Booster Collimator is orbit control at the collimator –At startup, initial attempts at controlling the horizontal orbit (rpos) resulted in poor Booster performance at high intensities. Our first order of business in commissioning the collimators, is to develop and understand orbit control at the collimators. –A plan needs to be developed by the Proton Source. This plan must account for: »Radial position control, Cogging, Booster Alignment, etc. –We will launch these studies, once we have prepared the plan Depending on the success of our orbit control, we might have to modify the present operational scenario of the collimators. In parallel to the orbit control project we should start considering what these alternatives are. We also must be able to measure the success of the collimators. –i.e. how much beam is loss in the Booster compared to the collimators –At present, we don’t have a viable plan to do this. –We could use the help of the experiment in developing this measurement system.
