AP2-Debuncher Injection AP2-Debuncher Injection Area 2004 Shutdown WorkArea 2004 Shutdown Work

August 2, 2004

What’s Today For?What’s Today For?

• Will the modifications reduce the beam steering hazards and ease injection tuning?

• What rare the physical risks to the Debuncher components?

• Do the modifications allow for easy/quick retreat if there are problems after attempting beam?

What’s happening?What’s happening?• Injection Septum

– Modification of removing material between Closed Orbit and Injection Channel

• Decreases amount of closed orbit bump • Common vacuum eliminates air gap and vacuum

windows

– Vertical motion of stand • Will use to center injection channel on beam

• D4Q4 SQC replacement with 2 LQBs– Injection orbit path designed to skim top of

extended lobe star beam tube inside SQC– LQBs allow larger beam tube.

What’s happening?What’s happening?• D4Q4 BPM

– Injection orbit path designed to skim large BPM.– Move BPM downstream where injection orbit is

closer to closed orbit.

• Injection Kicker– Motorizing stand to center upon beam

• Larger beam tube through LQs (4Q5 and new 4Q4 pair)– Replacing two separate pipes thru D4Q5– New pipe will nestle up into coils as far as

possible

AP2

Non-Mechanical Tunnel WorkNon-Mechanical Tunnel Work• Power Supply

– 1200A PS available; ready to move to AP50

• Cable Pulls and Terminations– LQBs power, – Stand motors, – new BPM, – moving BPM(?), – ion pumps, – gate valve

• Water (LCW)– Power supply– LQBs

From D. VanderMeulen

Non-Tunnel WorkNon-Tunnel Work• Controls/ACNET

– LQBs: Setting & Readback– ISEP motion control by old CAMAC interface– IKIK motion control by PLC

• Console Applications/ Software– LQBs

• P102: Modify bus cycling software• P60: Modify tune mults that currently uses D4Q4 shunt

– New Ion Pumps & Gate Valve• Add to P17 & P18

– LQB, VT403, & Debuncher BPM positions• P144: Debuncher orbit correction program

– New BPM and moved SEM• Yet to be written AP2 BPM DAQ and orbit correction program
