HINS 6-Cavity Test 3 Month Plan Jan 12, 2012

Current Schedule 2-3 day shutdown scheduled to start Jan 18 (Wednesday) to upgrade BPM system and reinstall slits and fast Faraday cup. Shutdown for H- upgrade scheduled to start Feb 6 (Monday). Estimate 3-4 weeks to finish all upgrade mechanical work. Lab shutdown still scheduled to start March 1. Main injector quads may be reclaimed at the end of March. New klystron scheduled to arrive in early spring.

BPM Upgrade Shutdown Install buttons on all blanked off BPM ports. Replace cavity wire scanner with a BPM. Install new can for slit scanner and fast Faraday cup. New BPM Location New can Location

Pre-upgrade Studies Perform cavity phase scans using new BPM. Tune cavities to specified amplitude and phases, and measure beam emittance using quadrupoles and slits. Document final settings before H- shutdown.

5 More realistic (?) schedule  Feb 1 st, H - source to alignment  Depends on how much time needed for alignment  Simply need to be early enough  Feb 3 rd, last H + run  Feb 6 th, start removing H + source  Mostly electrical first (cables and such), then mechanical (source and stand out)  Feb 16 th, new stand installed  Feb 24 th, H- source installed  Includes vacuum connected (may be not pumped down)  Includes all electrical connections  Feb 27 th, alignment  Feb 28 th, start commissioning  HV => Plasma => Beam 3 weeks

Other HINS Shutdown Activities Waveguide distribution from klystron to test area will be removed. Klystron will only power beam line. Modify klystron interlocks, to remove monitoring of RF test areas. Complete documentation necessary for remote operation of facility. LLRF work on vector modulator feed-forward.

H- Startup Will start (hopefully) sometime in early March, contingent upon good vacuum, working power supplies, controls, and safety approval. May need a week to optimize LEBT for best RFQ transmission. Retune cavities for transmission to diagnostic line. Measure emittance of new beam with slit scanner.

Loss of MI Quadrupoles NOVA project will want the spare MI quads when they are ready to construct magnet girders. Present commitment date is end of March. This will render diagnostic line and Buncher 2 useless, but RF work and beam through Cavity 4 can continue. These quads go away.

Other Items During AD Shutdown Complete 6-cavity test with vector modulator controls. New klystron due to arrive in spring. Current plan is to swap out klystrons (will this require mech. support?). Complete beam line design for 2.1MeV chopper test.
