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• Outdated DAQ• Difficult to integrate with existing software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

Beamline BPM Upgrade – Technical OverviewBeamline 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 / for position, || 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

lattice parameters Shot Data Acquistion (SDA) Expect existing applications to continue to see protons
with minimal changes More extensive modifications or new applications will be
needed to monitor anti-protons

Beam Line BPM Upgrade - SummaryBeam Line BPM Upgrade - Summary
An upgrade to the P1, P2, AP3, AP3, A1 BPM systems has been identified as necessary and is included as part of Run II Upgrades/Frequent Transfers project
Upgrade design draws on recent BPM upgrade experience (Tevatron, Recycler, NuMI)
Unique design for both 2.5 and 53 MHz operation
Design is largely complete; testing with beam is in progress at F23
Anticipated completion this summer MI upgrade will build on this experience

Filter Module TestingFilter Module Testing
1st Prototype from EE Support in February Miscommunication on how to evaluate two solid state
switch candidates Minimized usefulness of board (2 weeks)
2nd Prototype from EE Support Discovered issue with output op amp unable to supply
enough current over entire signal range (1 week) Began “Real Beam” testing at F23 (3 weeks)
• Found that gain/attenuation settings needed adjustment• Found large position variations – SW120 & temperature
Decided to make Prototype run of full board (2 weeks)
Total 2 months over estimated time to produce production boards
