Fiber-Optic Isolated Computer Control

Group3 Control is a fiber optically linked control system using distributed I/O modules called Device Interfaces, or DIs. A DI with the appropriate I/O boards installed is positioned at the point to be controlled or monitored.

Up to 16 DIs can be placed on each fiber optic loop coming from the loop controller installed in the host computer.

The Group3 Control system features dual port RAM in it’s loop controllers for added speed, and redundant calibration tables within the DIs and I/O boards for added system reliability.

Applications include monitoring and control of Ion Implanters, Electron Guns, Ion Sources, RF Accelerators, RFQ Accelerators, and LINAC Accelerators, to name a few.

Applications

  • University of Notre Dame, SNICS Ion Source
  • CalTech, Electron Gun
  • DOE, Spallation Neutron Source (SNS)

University of Notre Dame

SNICS Ion Source control and monitoring using a Pentium PC, LC3-PC-P, and two CN3 device interfaces, one at ground, and one at high voltage. The system is running with LabVIEW software.

CalTech

Electron Gun control and monitoring using a Pentium PC, LC1-PC-P, and four CN3 device interfaces, one at ground, one at 130kV, one at 150kV, and one at 160kV. The system is running with LabVIEW software.

US DOE

SNS Test System control and monitoring using a VME Crate, LC2-VME-P, and five CN3 device interfaces, two at ground, two at 30kV, and one at 50kV. This has evolved in to the control system for the H¯ ion source, comprised of more than 40 CNAs, 6 DIs, and 5 VME Loop Controllers.
