The OASYS project aims to produce commercially viable proof-of-concept results for two advanced machine protection applications of an existing optical fibre beam loss monitor (oBLM) device. An oBLM consists of a series of optical fibres run down the length of an accelerator structure (e.g. a beamline). When beam losses occur within the structure, showers of charged particles are produced. When these particles cross the optical fibres they produce Cherenkov radiation. This radiation propagates down the fibres and is detected by a Silicon PhotoMultiplier (SiPM) with specialised high-speed readout electronics. This signal provides time-of-flight information on the source loss point, allowing it to be located to within ~10 cm along the accelerator structure; a resolution unprecedented within existing loss monitoring technologies. This device has already been implemented at several international accelerator facilities in collaboration with D-Beam Ltd. The OASYS project aims to extend the functionality and applicability of this emerging technology.The two proposed oBLM-based applications are built upon slight variations on existing oBLM methodologies. The first, RF breakdown detection, has already been achieved with the oBLM at CLARA. OASYS will extend upon these preliminary results to provide verified proof-of-concept results benchmarked against existing technologies. The project will investigate improvements to fibre design, fibre placement and electronics design. The second methodology, superconducting quench detection, will require little alteration to the existing oBLM. OASYS will provide proof-of-concept results on this technique via investigations into fibre layout and signal analysis. The cohesion of significant experience in the use of the oBLM and two innovative concepts will provide a single commercially successful device. These techniques will be developed in an optics laboratory at first, before being implemented at accelerator facilities.The research project will also produce a machine learning-based analysis suite. This software will have the potential to perform automated machine optimisation and machine protection.A market for OASYS has already been assessed. Initially, the focus will be on supplying to synchrotron light sources (>50 facilities worldwide), as these are user-focused facilities and are continuously looking for innovative technologies to improve their user services. A further aim of this project is to prove the applicability of these technologies at linear accelerators. If this can be achieved it will open up the potential market to the 30,000+ linear accelerators worldwide. This would ensure the longevity of this technology. The market potential of any further applications identified during the project will also be assessed. These will be incorporated into the existing market analysis conducted on behalf of D-Beam and the proposer's group (Qi3, April 2019).The company D-Beam Ltd. will be involved throughout this project, helping to assess the requirements of producing commercial products from the research outcomes. The proposer also has pre-existing collaborations with further relevant companies, which will all provide support in specific areas throughout the project.The outcome of this project will be a commercially viable OASYS device for particle beam diagnostics, with a well-defined route-to-market and a long term plan for sustainability.

OASYS项目旨在为现有光纤光束损耗监测器（oBLM）设备的两种先进机器保护应用产生商业上可行的概念验证结果。oBLM由一系列沿着加速器结构（例如光束线）的长度延伸的光纤组成。当结构内发生束流损失时，会产生带电粒子簇射。当这些粒子穿过光纤时，它们产生切伦科夫辐射。这种辐射沿着纤维传播，并由具有专门高速读出电子设备的硅光电倍增器（SiPM）检测。该信号提供了源损失点的飞行时间信息，使其能够沿着加速器结构定位在~10 cm沿着内;这是现有损失监测技术中前所未有的分辨率。该设备已经在几个国际加速器设施与D-梁有限公司合作实施的OASYS项目的目的是扩展这一新兴technology.The两个拟议的基于oBLM的应用程序的功能和适用性是建立在现有的oBLM方法略有变化。第一，RF击穿检测，已经实现了与oBLM在ARMA。OASYS将在这些初步结果的基础上进行扩展，以提供针对现有技术的经过验证的概念验证结果。该项目将研究纤维设计、纤维放置和电子设计的改进。第二种方法，超导失超检测，将需要很少的改变现有的oBLM。OASYS将通过对光纤布局和信号分析的调查，提供有关该技术的概念验证结果。在使用oBLM和两个创新概念的重要经验的凝聚力将提供一个商业上成功的设备。这些技术将首先在光学实验室中开发，然后在加速器设施中实施。该研究项目还将产生基于机器学习的分析套件。该软件将有潜力执行自动化机器优化和机器保护。OASYS的市场已经评估。最初，重点将是为同步加速器光源（全球超过50个设施）提供服务，因为这些设施以用户为中心，并不断寻求创新技术以改善其用户服务。该项目的另一个目的是证明这些技术在直线加速器上的适用性。如果能够实现这一目标，将为全球30，000多台直线加速器打开潜在市场。这将确保这项技术的寿命。项目期间确定的任何进一步应用的市场潜力也将得到评估。这些将被纳入代表D-Beam和提案人小组进行的现有市场分析（Qi 3，2019年4月）。D-Beam有限公司将参与整个项目，帮助评估根据研究成果生产商业产品的要求。该项目的成果将是一个商业上可行的用于粒子束诊断的OASYS设备，具有明确的上市路线和长期的可持续性计划。
