Flying Wire & IPM Update 2/09/2010
Flying Wire Status Main Injector • Horizontal Operational • Vertical Operational Recycler: No Change • Horizontal Operational • Vertical has a binding feed-through. Problem is inside. TEV: No Change • All 3 wires are operational.
Booster IPM Notes Has • Horizontal and Vertical Operational • Electrostatic collection of Ions with up to 8 KV Clearing Field • 64 Anode strips spaced at 1. 5 mm – Approximately 60% copper, 40% space between strips. • 30 channels instrumented in each plane (64 total) – with 60 db gain amplifier – ~ 300 KHz • Samples once per turn throughout Booster cycle – ~19900 samples • Applications page on B 77
Booster IPM Notes 2 Needs to be Determined • Looking at Magnetic containment for collection of Electrons as in the Mark-II in MI. Beam Specs in NOVA Era • ~10 mm sigma at injection. 400 Me. V • ~4 mm sigma at extraction. 8 Ge. V • ~0. 5 e 12 particles per batch per turn minimum – In general we can see and make good measurements at 2 turns – (this is the minimum, have run as many as 18 turns) – Typical 10 -12 turns for Nu. MI and P-Bar Stacking. • Can use magnets to contain electrons. (Has been modeled by Alan Hahn and Andreas Jansson and will be updated. )
Main Injector IPM Has • Horizontal Mark-II Operational in Electron Mode • Magnetic containment of liberated electrons with: – up to 10 KV Clearing Field – 1 KGauss Magnetic Field • 120 Anode strips spaced at 0. 5 mm – Approximately 60% copper, 40% space between strips. • 72 Channels instrumented – with 60 db gain amplifier – ~ 300 KHz • 64 Channels Digitized • Samples once per turn – up to 65 K samples, (not quite a full cycle, limited by Comet Board) • Applications page on I 39
Main Injector IPM Beam Requirements • NOVA Era – 4. 5 e 12 – Slip Stack 95% – 6 Batches Maximum • 8 Ge. V Beam Size (99%) – 10 pi, 20 mm • 120 Ge. V Beam Size – 5 mm • Must be sensitive enough for tune up with single batch – 2 turns, ~ 1 e 12 • Working on: – Single Batch Gating – New Digitizer, potentially enough samples for a full MI cycle. – Jim Volk Magnet design with a single correction field. (Less beam line space. )
