This application seeks funding from STFC to support the development of a quantum gas jet-based beam scanner/target. QuantumJET will produce micrometer-focused beams of atoms and molecules for non-invasive, high resolution beam monitoring applications, as well for use as targets in storage rings. As a beam monitor, this novel device will benefit essentially any high intensity, high energy accelerator where commonly used beam monitors no longer work, including high power accelerators such as the Spallation Neutron Source (SNS) or Accelerator Driven Systems (ADS) . It will also mark a breakthrough for accelerators that rely on very small cross sections that cannot be resolved with curtain-shaped gas jets, such as linear colliders. More widely, the technology will be very attractive for any accelerator or light source that would benefit from non-destructive online beam monitoring, including medical accelerators and ion implanters. As a versatile gas target, a well-defined jet provides an ideal basis for studies into total and fully differential cross sections in beam lines and storage rings. Of particular interest is the integration in low energy antiproton rings such as the AD and ELENA at CERN, as keV antiprotons give insight into correlation process on the attosecond timescale, thus paving the way for a detailed understanding of fundamental physics concepts. Moreover, well-controlled, high-density gas beams may also find use as confined plasma sources for electron accelerators , plasma beam dumps or "refractive" kickers for extremely rigid electron beams .Underpinning R&D was carried out in the QUASAR Group, based at the Cockcroft Institute (CI) on the campus of Daresbury Laboratory. The Group is very well connected with the global accelerator community and has been a recognized leader in beam diagnostic R&D for more than a decade. Previous work was supported by the HL-LHC-UK project, funded by STFC and CERN, and the Cockcroft Institute core grant ST/G008248/1. It was done in close collaboration with D-Beam Ltd, an STFC CERN Business Incubation Centre alumnus.

这项申请寻求来自STFC的资金，以支持基于量子气体喷射的束流扫描仪/靶的开发。QuantumJET将生产微米级聚焦的原子和分子光束，用于非侵入性、高分辨率的光束监测应用，以及用作存储环中的目标。作为一种束流监视器，这种新型设备基本上将使任何通常使用的束流监视器不再工作的高强度、高能加速器受益，包括散裂中子源(SNS)或加速器驱动系统(ADS)等高功率加速器。对于依赖于非常小的截面的加速器来说，这也将标志着一项突破，这些截面无法用窗帘形状的气体射流来解决，比如线性对撞机。更广泛地说，这项技术对任何将受益于非破坏性在线束流监测的加速器或光源都非常有吸引力，包括医疗加速器和离子注入机。作为一种多用途的气体靶材，定义良好的射流为研究束线和储存环中的全截面和全差截面提供了理想的基础。特别令人感兴趣的是在低能反质子环中的积分，如欧洲核子研究中心的AD和Elena，因为KeV反质子提供了在阿秒时间尺度上的关联过程，从而为详细理解基本物理概念铺平了道路。此外，控制良好的高密度气体束也可能被用作电子加速器的受限等离子体源、等离子体束倾倒装置或极端刚性电子束的“折射”激励器。该集团与全球加速器社区建立了良好的联系，十多年来一直是束流诊断研发领域公认的领导者。之前的工作得到了由STFC和CERN资助的HL-LHC-UK项目和Cockcroft研究所核心赠款ST/G008248/1的支持。该项目是与STFC CERN企业孵化中心的校友D-Beam Ltd密切合作完成的。
