  1. Current NML Layout

  2. Current NML Layout • Overall length of building is 72M • 3 cryomodules with feed and end cans ~40M • Not enough room for both photoinjector and downstream diagnostics before beam dump • Decision made to install first cryomodule with space for photoinjector and CCII • Physical layout of modulators and relay racks not yet determined • Network fiber to NML installation • Cryo fiber between lab B and NML – done • Fiber from NML to training center to mac room – in progress

  3. Current NML Layout • Two 5MW Klystrons: RF gun and cryomodule • Embedded processor for modulator control and interlocks • eCos operating system with custom protocol for Epics interface • Beta version of Epics application ready • Two 500KW Klystrons: CCI (from photoinjector) and CCII • Modulator control needs interface • Possibly two low power 3.9 GHz klystrons

  4. Current NML Layout • RF Interlocks • Embedded processor for control and interlocks • Testing/debugging at CCII • Will be used for 3.9GHz coupler conditioning test stand • Epics interface and conditioning sequencer

  5. Current NML Layout • Cryo Controls • Existing GUI for various cryo subsystems at MDB. NML will be similar, need input from cryo people. • Have archive and plot applications, working on save/restore • LLRF • Simcon 3.1f (Fermi version) Gustavo Cancelo et al. • Doocs • Epics

  6. Current NML Layout • The photoinjector at A0 • Most everything will be moved to NML • The control system (IRMs) does not necessarily move • 62 Power supplies: A/D, D/A, status, control • 66 Misc. A/Ds: vacuum, temperatures, etc. • 13 Stepping motors • 35 Digital control & status devices: flag actuators, gate valves, camera lights, video mux • 3 Servo motors: cave, laser, and transport iris • 20 Event plus delay timer/gate channels • 12 2MHz digitizer channels

  7. Current NML Layout • The Schedule • First cryomodule arrives July 2007 • Cryo, vacuum, and RF interlocks controls available • RF interlocks commissioning and coupler conditioning (warm) into winter of 2007 • Dismantle/move photoinjector late summer 2007 • Gun will be ready ~December 2007 • Second cryomodule in 2008

  8. Current NML Layout • Some Questions • Clock/Timing system • The existing clock system is adequate for initial conditioning. What are the requirements for NML? • Data acquisition and control • Power supply control • Danfysik power supplies for solenoids and spectrometer magnet • Generic A/Ds, stepping motors, gate valves, etc. • Special applications • Machine Protection System (MPS) • 40KW beam power can burn holes
