Topical Workshop on Beam Loss Monitors

Europe/Zurich
Residencia d'Investigadors, Barcelona

Residencia d'Investigadors, Barcelona

Carrer de l’Hospital, 64 08001 Barcelona Spain
Description

To fully understand and optimize the properties of a beam in an accelerator, storage ring or light source, a beam loss monitoring system is essential. 

This typically includes localized detectors with high sensitivity and dynamic range, as well as distributed systems, such as optical fibers, to cover the entire machine range. Numerical studies underpin system design and allow for a detailed analysis of experimental data.

This two-day international workshop will provide an overview of the current state of the art in beam loss monitoring. It will discuss research and development being undertaken and ambitions to further improve the performance of existing and future devices. It will also focus on Monte Carlo tools and accelerator collimation systems.

The workshop will be held at the Residencia d' Investigadores, Barcelona, close to the city centre.

In addition to invited talks, there will be opportunities for contributed talks which will be selected from all submitted abstracts.

Registration deadline 31 August 2016

Abstract submission deadline  15 August 2016

      BLM in the context of machine protection

      Any particle accelerator with damage potential in its beams or its machine components requires a potent machine protection system. High power particle beams, or beams with a high power density, can directly damage accelerator structures, whilst beam induced heating of superconducting structures can trigger a phase transition to the normal conducting state (quench). A good beam loss monitoring (BLM) system is therefore one of the key elements for machine protection. Such a system can either directly trigger a fast beam abort or inhibit subsequent beam pulses, depending on criticality and machine type. This talk discusses the role of a BLM system in machine protection, including aspects related to beam transfer and collimation with the real life experience of LHC BLM operation serving as illustrative examples. Dependability and design criteria are also reviewed.
