Pioneering Science and Technology Office of Science U.S. Department of Energy 12 LLRF development FNAL, DESY, KEK already actively pursuing this with regard to test stands (ILCTA, TTF, ATF-2, etc) [Feb 9-10 th workshop] Should determine how we can best integrate the test stands into other controls related development activities.

Pioneering Science and Technology Office of Science U.S. Department of Energy 13 Timing / RF phase reference distribution Various issues discussed at Jan meeting, including… Evaluate and demonstrate various options -Trench test of fiber system (vs coil in oven) -Sector test – the copper part (local distribution). -Two-channel receiver comparator scheme -Low-cost way of building a vcxo with sufficient performance? -“To chop or not to chop” Different schemes to meet the bunch compressor requirements. Failure modes and effects analysis. Pursue HOM phase detector scheme.

Pioneering Science and Technology Office of Science U.S. Department of Energy 14 Feedback development issues Various issues discussed at Jan meeting, including… How do the beam-based feedback systems deal with exceptions? -Startup, beam loss, MPS trip, etc -Detecting and handing bad sensors or actuators. Integrated simulation of LLRF and beam-based feedback. Interplay between the various feedbacks and feed-forwards? How does beam-based feedback help the rf specs? How many intra-train feedbacks do we have, and how many pulses do they collectively take to converge? Should beam trajectory feedback be several individual loops or a single global system?

Pioneering Science and Technology Office of Science U.S. Department of Energy 15 High Availability control system demo R&D Roadmap (starting point) -Claude’s proposal - ATCA + EPICS iocCore + shelf manager + ICE middleware - Claude to set up discussion with interested parties. - Develop an AMC module to plug in / integrate with Claude’s ATCA crate. -How do we utilize the test stands (ILCTA, ATF, TTF)?
