项目摘要
The High Luminosity Large Hadron Collider is a major accelerator upgrade at CERN that will increase the luminosity delivered to the ATLAS and CMS experiments by an order of magnitude. The upgrade will enable the search for new, rare particles and precision measurements of the standard model of particle physics. The HL-LHC will achieve this luminosity increase by a combination of focusing the proton beams more tightly at the interaction points, increasing the beam current and crab-rotating the bunches to maximise the geometric overlap between the colliding beams. Optimising the performance of the crab-cavities at the HL-LHC requires challenging new instrumentation that can measure the transverse shape of a 1ns long proton bunch passing by at nearly the speed of light.To address this exciting challenge, Prof Stephen Gibson leads the UK collaboration between the CERN Beam Instrumentation group and Royal Holloway, University of London (RHUL) to develop novel Electro-Optic Beam Position Monitors (EO-BPM). The aim is to use electro-optical crystals that have a time response in the picosecond range to enable an ultra-fast optical response to the passing relativistic bunch. The PhD candidate will join this CERN-RHUL collaborative experimental program to develop electro-optical BPMs for tests at CERN's flagship accelerator, the LHC.The PhD position will be based at Royal Holloway, University of London, where the student will be initially trained to perform experimental bench tests in laser rooms and clean rooms at Royal Holloway, and to perform electromagnetic simulations of the relativistic bunch, the electro-optic response and develop ultrafast optical detection techniques. The student will also attend lectures in accelerator physics at the University of Oxford during the first year, as part of the training provided by the John Adams Institute for Accelerator Science.After the initial training in the UK, the student will move to CERN to participate in operational beam tests of the prototype at the SPS accelerator. The student have the opportunity to acquire and analyse data from the EO-BPM device during Run-III of the LHC, with the aim of validating this new method for deployment of these new devices at the HL-LHC. Following successful demonstration, publications of the results and participation in international conferences is expected.The student would join a friendly team at RHUL and benefit from the direct supervision of Prof. Stephen Gibson, and collaborate with the team at CERN. The PhD candidate would also benefit from the wider support and training network of the John Adams Institute for accelerator science, a centre of excellence in the UK for advanced and novel accelerator technology, providing expertise, research, development and training in accelerator techniques, and promoting advanced accelerator applications in science and society.
高光度大强壮的强子对撞机是CERN的主要加速器升级,它将增加传递给ATLAS和CMS实验的光度。升级将使粒子物理学标准模型的新的,稀有的颗粒和精确测量值搜索。 HL-LHC将通过在相互作用点更紧密地聚焦质子束,增加束电流并旋转束束以最大化碰撞光束之间的几何重叠,从而增加质子梁的组合,从而达到这种发光度。优化HL-LHC上螃蟹腔的性能需要挑战新仪器,可以衡量1NS长质子束的横向形状,几乎以光的速度经过。为了应对这一激动人心的挑战,Stephen Gibson教授领导英国教授在伦敦皇家大学(RHUL)(RHUL)之间的CERN BEAM仪器组合(RHUL)之间的合作,以开发新颖的Electrom-B-B-B-B-B-B-BPMER-BPMEOR-BPMEOR-OPTITS(EE)(EE)(EE)(EE)(EE)(EE)(EE)(EE)(EE)(EE)。目的是使用在皮秒范围内具有时间响应的电流晶体,以使对传递相对论束的超快速响应能够进行超快速的响应。 The PhD candidate will join this CERN-RHUL collaborative experimental program to develop electro-optical BPMs for tests at CERN's flagship accelerator, the LHC.The PhD position will be based at Royal Holloway, University of London, where the student will be initially trained to perform experimental bench tests in laser rooms and clean rooms at Royal Holloway, and to perform electromagnetic simulations of the relativistic bunch, the电声响应并发展超快的光学检测技术。该学生还将在第一年在牛津大学的加速器物理学讲座上,作为约翰·亚当斯加速器科学研究所提供的培训的一部分。在英国进行初步培训后,该学生将搬到CERN参加SPS Accelerator在SPS Accelerator的Prototype toperational Beam测试。该学生有机会在LHC运行期间从EO-BPM设备中获取和分析数据,目的是验证这种在HL-LHC上部署这些新设备的新方法。经过成功的演示,预计结果和参与国际会议的出版物。该学生将加入Rhul的友好团队,并受益于Stephen Gibson教授的直接监督,并与CERN的团队合作。博士候选人还将受益于约翰·亚当斯加速器科学研究所的更广泛的支持和培训网络,这是英国高级和新颖加速器技术卓越中心,提供加速技术的专业知识,研究,开发和培训,并促进科学和社会中的先进加速器应用。
