System Safety and Safety Systems for Accelerators


Kelly Mahoney and Sandra Prior, TJNAF

Great effort is extended toward the safe operation of accelerator facilities to protect personnel as well as equipment. Continued new developments and components are available to achieve the goals of accelerator design in a safe environment. This course is offered to provide an introduction to the physics and technologies applied to safety systems. Traditional as well as new technologies will be discussed to provide an up to date overview of the field. This course is designed specially for operators, technicians, engineers and physicists to get introduced into this field or to absorb the latest technical developments and will be followed next week by a similar course on Radiation Safety.

This course will present material on the specification, design, and analysis of electrical/electronic/programmable electronic safety systems for use in the protection of personnel, equipment, and the environment. Basic principles of accelerator system safety will be presented along with examples of systems in use today. Systems covered include ionizing radiation interlocks, non-ionizing, e.g. laser and RF, safety interlocks, access control systems, machine protection devices, beam abort and blocking devices, and oxygen deficiency monitoring systems. Topics covered include hazard analysis, reliability calculations, and high assurance system design. The system safety part of the course will cover statutory and regulatory requirements for safety in accelerators as well as the development and management of safety systems. Topics include statutory requirements, safety assessment, safety envelopes, and quality assurance. During the course, students will be tasked with evaluation, design, and analysis of safety systems for a hypothetical accelerator. Prerequisites: Basic undergraduate background in physical science and a mathematical background at least through first-year undergraduate calculus.
