CD Accelerator Activities Meeting

• Update on SMTF activities

Update on recent SMTF activities

• Capture Cavity 2 Test
• Two DESY cavity controller modules SIMCON2.1
  assembled and tested.
• A SIMCON2.1 test stand running cavity controller
  and simulator is functioning at FCC (ESE test
  area).
• DESY DAC8 Function generators have been tested
  and will be integrated to CC2 system.
• Simcon2.1 firmware (10K VHDL lines) has been
  compiled using an old version of
  Leonardo Spectrum.
• Simcon2.1 software
• Currently running a Matlab-based application.
• Two Sparc stations running DOOCS.
• Ron and Luciano are still working to get some
  application modules to talk to the hardware,
  server, etc.

Capture Cavity 2 Test

• SIMCON2.1 production
• About half of the production has been launched.
  The other half is waiting funding. DESY may buy
  10 Xilinx development kits (25K).
• ESS group will collaborate with assembly and
  testing.
• CC2 setup will be modified to run at 3.9 GHz by
  Jan/Feb 06. Most of the LLRF system stays the
  same. The master oscillator is being designed to
  operate at 1.3 and 3.9 GHz.
• Plan to install an injector, RF gun, and a couple
  of cavities at Meson Lab (2006).
• Plan to install an Horizontal Test Facility and a
  Vertical Test Facility at IB1 (Industrial
  Building 1).

SMTF activities at CD

• Next Milestone Control of full cryogenic module
  with 8 cavities. (end of 2006 or 2007).
• Cavity control algorithms Explore models.
• Cavity control hardware and firmware
• ILC and TESLA hardware will diverge. We want to
  start a developing a cavity controller.
• Evaluate control algorithms in processor and FPGA
  platforms.
• New tool MatlabSimulinkSys_Gen implements
  Maltab code into VHDL.
• Cavity control simulations Cavity control
  algorithms.
• Feedback control algorithms are based on cavity
  models and signal disturbances. This is a
  complicated problem because the cavities interact
  with each other. The control problem is most
  likely nonlinear and Multi-output multi-input).
  More than one control loop will be needed. We
  must incorporate Beam loading, and detuning into
  the control strategies.

SMTF activities at CD

• DAQ What hardware is needed?
• Can we buy off-the-shelf or use available
  hardware like PTA2?
• Application software. BPM applications will
  certainly help.
• Slow Control and Interlocks
• We are already collaborating with P.Prieto. This
  collaboration could grow.
• Timing hardware
• M.Krucera is providing the timing hardware for
  CC2. B.Haynes has designed timing hardware for
  TeV and MI BPMs. We could collaborate in the
  future.
• Proton Driver SCREAM
• SCREAM is a Matlab based software that simulates
  the complete Linac. CD is participating in this
  effort. Some framework commonality with ILC but
  very different parameters.
