The objective of the workshop is to bring together experts working on machine protection systems for accelerator facilities with high brilliance or large stored beam energies, with the main focus on linear accelerators and their injectors. The workshop should establish a coherent view of failure modes and consequences for linear accelerators and review the current state of the art in machine protection systems. The participants will benefit from the experience of colleagues who have designed, commissioned and operated such systems.
The workshop will provide input to the design of machine protection systems at future accelerators, in particular for CLIC and ILC. It also should promote synergies in the development of protection systems at different accelerators.

Wednesday 6 June (experience and future needs)
- Introduction.
Setting the scene: purpose of machine protection, risks, challenges, issues and objectives.
-
Machine protection and operational availability, issues and solutions.
Review of existing solutions and challenges faced by future installations:- Experience from LHC, Flash, light sources
- Challenges for ILC, CLIC, XFEL, ESS
-
Beam loss mechanisms.
Experience of existing and previsions for future accelerator complexes, addressing three types of beam losses and their potential impacts:- Operational beam losses: quasi continuous losses (e.g. beam gas induced) that form the loss background that has a major impact on the radiation environment in the accelerator.
- Equipment failure induced beam losses, which – if ill controlled – may lead to major damage of the accelerator structures.
- Transient beam losses, or beam losses related to changing environment (temperature drift, ground motion, ufo, others).
-
Failure onset detection.
This section will address the detection of failures that may lead to uncontrolled beams.- Beam Quality Assessments (for active systems and Post Pulse Analysis)
- Equipment failure detection
-
Failure mitigation.
Reviews of various types of failure mitigation:- Passive protection (masks , materials, collimators, non linear optics)
- RT protection
- Safe by design
- Interlock systems (equipment and post pulse assessment)
