An exciting new project recently submitted to the European Strategy for Particle Physics is the prospect of a Gamma Factory (GF) at CERN, as part of the Beyond Colliders Programme. The GF is a new technique to generate ultra-intense and highly energetic beams of photons by making use of the existing accelerator infrastructure CERN. Instead of circulating protons in the LHC, partially-stripped ion beams are accelerated and made to interact with photons from an intense laser beam. The excited ultra-relativistic ions subsequently decay and emit photons that are relativistically boosted and thus generate highly collimated, high-intensity photon beams, with an unprecedented photon energies compared to existing light sources. Such photon beams are useful for myriad studies and applications, and can be scattered from a target to produce secondary beams of polarised electrons, polarised positrons, polarised muons, neutrinos, neutrons and radioactive ions. These beams offer a variety of new research opportunities at CERN in a wide area of fundamental as well as applied physics.An initial Proof-of-Principle experiment at the CERN Super-Proton Synchrotron is being developed by a pioneering international GF collaboration of 62 scientists, 5 of whom are based at RHUL. The work proposed here, seeks to build on initial studies using software tools created by the RHUL group. These tools will be developed to enable a holistic approach to seamlessly simulate the passage of partially-stripped ions in the accelerator, their interaction with the photons, excitation and subsequent decay, using an extension of Geant4. We will apply these new tools to study and optimise the efficiency of the photon-ion interaction and determine the resulting distribution at the detector. In this was the design of a Proof-of-Principle experiment at the CERN SPS can be studied and optimised.

最近提交给欧洲粒子物理战略的一个令人兴奋的新项目是在欧洲核子研究中心建立伽马工厂（GF）的前景，作为超越对撞机计划的一部分。GF是一项利用欧洲核子研究中心现有的加速器基础设施产生超高强度和高能量光子束的新技术。在大型强子对撞机中，部分剥离的离子束被加速，并与来自强激光束的光子相互作用，而不是循环质子。受激发的超相对论性离子随后衰变并发射光子，这些光子被相对论性地增强，从而产生高度准直的高强度光子束，与现有光源相比，光子能量前所未有。这样的光子束在无数的研究和应用中都很有用，并且可以从一个目标散射出来，产生由极化电子、极化正电子、极化μ子、中微子、中子和放射性离子组成的二次光束。这些光束为欧洲核子研究中心在基础和应用物理的广泛领域提供了各种新的研究机会。欧洲核子研究中心超级质子同步加速器的初步原理验证实验正在由62名开创性的国际GF合作科学家开发，其中5人在RHUL工作。这里提出的工作，试图建立在使用RHUL小组创建的软件工具的初步研究的基础上。这些工具将被开发成一种整体的方法来无缝地模拟部分剥离离子在加速器中的通过，它们与光子的相互作用，激发和随后的衰变，使用Geant4的扩展。我们将应用这些新工具来研究和优化光子-离子相互作用的效率，并确定探测器处的结果分布。在这是一个原理验证实验的设计，在欧洲核子研究中心可以研究和优化SPS。
