SMTF Controls

• Dennis J. Nicklaus
• Fermilab
• ICALEPCS 2005

2
SMTF

• SMTF Superconducting radio frequency Module
  Test Facility

3
SMTF

• Main Goal Develop U.S. Capabilities in high
  gradient and high Q superconducting accelerating
  structure in support of the International Linear
  Collider.
• Proton Driver, RIA, 4th Generation Light Source
  and other accelerator projects
• Expanding upon existing SCRF expertise at
  Argonne, Cornell, Fermilab Jefferson Lab, MSU

SMTF Controls People

• Many contributors Ron Rechenmacher, Sharon
  Lackey, Ruben Carcagno, Geoff Savage, Vladimir
  Sirotenko, Vince Pavlicek, Gustavo Cancelo, Mike
  Kucera, Fritz Bartlett, and Luciano Piccoli under
  the direction of Helen Edwards and Paul Czarapata.

6
SMTF Goals

• Provisional goal is to have three U.S. and one
  European 1.3 GHz ILC cryomodules under test, with
  beam, by the end of 2009

7
SMTF Fermilab Siting

• Initial tests at Fermilabs Meson lab
• Fall 2005 test of single 1.3 GHz 9-cell TESLA
  cavity (RF, cryo, no beam).

8
Fermilab Siting

• Move the NICADD (Fermilab A0) photoinjector to
  Fermis New Muon building to use as a test
  beamline
• Produces low emittance, high-intensity electron
  beam

9
Controls Definition

• Convened panel of experts in early 2005
• Debated merits of ACNET, EPICS, and DOOCs
• Recommendation All are suitable. Pick one
  control system while recognizing there is much
  EPICS expertise with the SMTF collaboration
• Recognition of reality short term scheduled
  goals imply a mix for now.

10
Important Notice

• SMTF Controls ! ILC anything.

11
Current Status and Work

• Cryogenics
• LLRF
• Modulator
• Klystron Interlocks
• Timing

12
LLRF Controls

• DESY-provided Simcon FPGA-based LLRF controller
  (single-cavity) with initial MATLAB interface and
  in-progress DOOCS interface running on VME-based
  Sparc SBC.
• DESY-provided ADC and DAC cards with DOOCS
  interfaces.

13
Cryo Controls

• Replicate and enhance ACNET-based control over
  PLCs
• EPICS EDM displays to Epics OPC interface to OPC
  Server to PLCs.

15
Modulator

• PC/104 board with digital and analog I/O running
  eCos OS
• In use for other Tevatron controls at Fermilab
• EPICS ported to eCos for use at SMTF

17
Klystron Interlocks

• Short term re-using IRM-based system (IRM
  parameter pages) from previous experiment at
  Fermilab.
• Replace with custom VME cards controlled by
  conventional EPICS VME IOC.

18
Timing

• Industry Pack IP-177 8-channel delay timer
• Common design in many applications at Fermilab
  and elsewhere

19
Conclusions

• As expected, using a mix of several control
  systems for the short term (IRM, EPICS, DOOCS,
  Matlab). Converging?
• DOOCS contributions from DESY collaborators are
  integral parts of the system.
• Lots of efforts in understanding DOOCS and EPICS
  at Fermilab.
