  2. Beam Line BPM Upgrade • Introduction/Motivation • History • Technical Overview • Status • Software • Implementation Steps • Acknowledgements • Summary BPM Upgrade

  3. Beam Line BPM Upgrade - Introduction • Part of the ‘Rapid Transfers’ Run II Upgrade Project • Beam Line Regulation • Software • Oscillation Feedback & Control • Diagnostics • Commissioning • Ultimate goal • Accumulator to Recycler transfers every ~30 minutes and completed in 1 or 2 minutes BPM Upgrade

  4. Beam Line BPM Upgrade - Motivation • 1.3.6.5.1 Beam line BPM upgrade • BPM current use • Reverse protons • Minimum 30 uniform 53 MHz bunches • A few E11 intensity • Beam conditions purposely varied during shot set up to minimize necessary intensity • currently no pbar beam line BPM data • Reverse proton data sufficient for good pbar transmission • Electronics limitations • Low intensity • bunch structure • Outdated DAQ • Difficult to integrate with existing software • Rapid Transfers - no routine reverse proton tuneup for rapid transfers • Use pbars to monitor beam line performance • Use data to feedback to beam lines tune BPM Upgrade

  13. Beamline BPM Upgrade – Technical Overview • Use BPM pickups already in place (4 styles) • MI8, Main Ring, Accumulator, Debuncher • Use cables currently installed (RG8/RG213) • Examined whether pre-amps needed • Use Echotek digital receiver to digitize and process analog signals • Use D/S for position, |S| for intensity • Used in Recycler, NUMI, & Tevatron • System design draws heavily upon Recycler, NUMI, and Tevatron systems • System Design based upon NUMI model • Front-end software from Recycler/NUMI • Same VME crate, Echotek & Clock boards used in Tevatron BPM Upgrade
