RF integration – tasks in general LSA integration – virtual parameters, value generators, Makerules • Create virtual parameters • Generate operational parameter settings, trim settings, verify parameter hierarchies and Makerules FESA class testing • Import parameters from FESA devices • Test operational scenarios (COAST, economy, etc. ) • Generate operational parameter settings, trim settings, verify parameter hierarchies and Makerules Application development • Develop user interfaces based on operational needs and FESA interfaces Hardware integration tests • Drive operational settings down to hardware; verify signals Kevin Li - SPS MCM 3

RF integration – upcoming milestones / tests • Virtual parameters and high level parameter model (generation for LHC, Fixed target, Ions) • Bucket area, voltage programs, voltage partitioning, radial steering, FFA, … • Still to do: refine synchrotron frequencies taking into account 800 MHz; same for LQR controller • RF Timings: • Application integration – ongoing with regular testing (adding still consistency tests with respect to reference settings, alarms generated by FESA class) • FESA class tests, read/write, COAST (what about economy modes? – OP test 14. July) • Import and generation – beam control (status? If not yet done, OP generation test 14. July) • Cavity control timings – integration, generation tests (RF/OP test 28. July) Constant bucket area (0. 6 e. Vs) Injection 2 s into ram p Constant voltage • Function generator: • Write single cavity voltage function • Generate function, trims, for different cycles (COAST, maximum, minimum values, wrapping, maximum number of points etc. ? ) (OP test 14. July) • Acquisition: • FESA class tests with simulated signals • Application for monitoring and control – first version • Synchro and phase loop acquisitions + phase and position acquisitions (RF/OP test 4.

RF integration – upcoming milestones / tests • Cavity control • Parameter import (early July) • Full top-down generation (up to FESA level) of all actual cavity control parameters (LHC, SFT, ions) • • • Voltage, phase set-points (OP test 28.

RF integration – upcoming milestones / tests • Beam observation • BQM checks (FESA updates – test in simulation mode; RF once f_rev/f_RF is available – end November) • ABWLM checks (FESA updates, some updates – test reading from device; RF once f_rev/f_RF is available – end November) • Tomoscope strategy with timeline (SPS MCM – by end of year… depends on progress with optical fiber connections) • Some adaptations of Fabio’s application • J. F. Comblin adaptation of PSB GUI for the SPS • Beam observation application ready (OP test 10.
