What We Do
The Collider Accelerator Department (C-AD) Controls Group designs, develops and supports computing solutions for the effective and reliable control, monitoring, and analysis of the injectors and storage rings within the Collider-Accelerator Department.

The Controls Hardware Group maintains more than 13,000 modules, chassis, fiber optic components, PLCs, and specialty items. Together they combine to provide the approximately 2 million control points over all the systems. The primary Controls hardware platform is the VMEbus chassis, with 315 of these online throughout the facility. Each chassis contains a powerful processor card, and on average contains an additional 10 to 20 custom and commercial VME modules, providing a wide variety of functions and utilities. Some of the types of VME modules include Function Generators, Analog I/O boards, Digital I/O boards, Scalars, Motion Controllers, and specialty Timing boards.
In addition to the VMEbus chassis and their many boards, some of the more notable systems include over a 1000 Power Supply Interface modules, a large fiber optic distribution system, unique distributed timing systems (including the Real Time Data Link, Beam Sync Link, and Event Links), the Beam Permit Link (used for machine protection), a PLC based power supply control system, the Ground Fault monitoring system, and a distributed Temperature Collection system.
develops, improves, and maintains the access controls for all of the accelerators, transport lines, and stand alone experimental facility enclosures as defined by C-AD and approved by the C-AD Radiation Safety and Accelerator Safety Systems Review Committees. This includes all gate access controls, radiation interlock systems, and oxygen deficiency detection (ODH) and response systems used for the accelerator complex and R&D facilities.
The Access Controls Group consists of approximately 120 monitored access gates and about 40 ODH monitoring and response systems. The LINAC, Booster, and AGS use relay logic systems for the access controls with about 700 relays in those systems. The rest of the access controls utilize Programmable Logic Controllers (PLC’s) on two separate controllers/control chains. There are about 60 PLC’s in these systems. The systems also consist of 6 Iris recognition and key management token systems, 80 card reader access systems, and 40-access point video camera and switching systems. Each year these systems are recertified, taking about 80 days per year to perform all the functional safety tests.
