CesrTA Status Report Mark Palmer July 8, 2009

Overview Recent News Completed Run #3 (May 12 – June16) 109 of 240 planned running days now provided Major focus on commissioning efforts CTA09 (June 25-26) https://wiki.lepp.cornell.edu/ilc/bin/view/Public/DampingRings/CTA09/WebHome Major review of experimental program 40 participants Planning for next 4 runs (Aug ’09, Nov-Dec’09, approx. Mar ’10, approx. Jul ’10) Organize shift from commissioning focus a experimental focus Final upgrade down nearing completion Machine Startup – July 23rd Next run starts July 31st (to Sept 8th) July 8, 2009 ILC AS-TAGL Meeting

All Major Ring Modifications Complete CESR Reconfiguration L3 EC experimental region PEP-II EC Hardware: Chicane, upgraded SEY station (coming on line in May) Drift and Quadrupole diagnostic chambers New EC experimental regions in arcs (wigglers a L0 straight) Locations for collaborator experimental chambers CHESS C-line & D-line Upgrades Windowless (all vacuum) x-ray line upgrade Dedicated optics box at start of each line Detectors share space in CHESS user hutches L0 region reconfigured as a wiggler straight CLEO detector sub-systems removed 6 wigglers moved from CESR arcs to zero dispersion straight Region instrumented with EC diagnostics and mitigation Wiggler chambers with retarding field analyzers and various EC mitigation methods (fabricated at LBNL in CU/SLAC/KEK/LBNL collaboration) All Major Ring Modifications Complete CESR Ring July 8, 2009 ILC AS-TAGL Meeting

Status Update Key tasks: BPM system upgrade: xBSM upgrade: Commissioning work continued during May-June run. Pushing towards full switchover to new system by late summer xBSM upgrade: Commissioning continued work during May-June run including first single-pass measurements Complete electron line deployment during present down and commission (underway) 4ns upgrades 4ns feedback system commissioned during May-June run Upgraded 4ns digitizers for xBSM (component testing during Aug run a targeting standard operation by Nov-Dec run) L3 EC Hardware Chicane and EC chambers commissioned during May-June run SEY station development and testing underway (in situ measurement upgrade of SLAC hardware) New EC vacuum chambers Wiggler chambers with grooves and electrode mitigation (CU-KEK-LBNL-SLAC) [Groove chamber in preparation for installation Aug 20] Upgraded RFA detectors under development (first units installed) Diagnostic quadrupole chamber for L3 experimental region (installed) Collaborator chambers: CERN (a-C coating - installed); FNAL (enamel with electrode – late 2009); SLAC (new groove design - installed) Reviewing requirements for L3 NEG-coated chamber test Additional chambers depending on initial results through remainder of program EC solenoid windings on CESR drifts (underway) 4 runs planned over course of next year Each approximately 1 month duration July 8, 2009 ILC AS-TAGL Meeting
