LLRF for high power facility researching high gradient RF Structures for linear colliders and other applications

高能电子可以用来研究物质的结构。它们可以用来制造用于科学、医学和安全成像的x射线。在许多应用中，电子被利用普通导电射频结构加速到高能量。这些结构通常构成直线加速器（LINAC）或同步加速器的一部分。这些结构在非常高的加速度梯度下容易发生电击穿。高梯度降低了总成本。这笔拨款购买的设备增加了研究、开发、测试和调节射频加速结构的能力。这一补充对于详细分解研究的基础研究是必不可少的。减少调节时间、降低击穿率和提高结构性能的研究对于降低成本、提高可负担性和各种应用（包括未来的线性对撞机）的亮度至关重要。目前的早期技术发展，该设施将采用包括：-1。一种用于非洲放射治疗的新型直线加速器的原型设计。未来x射线自由电子激光器高梯度结构的发展。与英国工业界一起研究用于癌症治疗的高能电子束的最佳结构与英国工业合作开发货物扫描LINAC辐射对调理率的影响使用可拆卸背板的不同材料的射频击穿率7。磁场对击穿率的影响（对介子和电子注入器很重要）

High energy electrons can used to study the structure of matter. They can be used to create X-rays for imaging in science, medicine and security. For many applications electrons are accelerated to high energies using normal conducting Radio Frequency structures. These structures typically form part of a linear accelerator (LINAC) or a synchrotron. These structures are prone to electrical breakdown at very high acceleration gradients. High gradients reduce overall costs. The equipment being purchased with this grant adds capability to a facility for researching, developing, testing and conditioning RF accelerating structures. This addition is essential for fundamental research into detailed breakdown studies. Research that reduces conditioning time, reduces breakdown rates, and increases the performance of structures will be important for reducing costs, increasing the affordability, and the luminosity of various applications including a future linear collider. Current early technology developments, where the facility will be employed include:-1. Prototyping a novel LINAC for radiotherapy in Africa2. Development of higher gradient structures for a future X-ray free electron laser3. Studies with UK industry into the optimum structures for very high energy electron beams for cancer therapy 4. Development of cargo scanning LINAC with UK industry5. Effect of radiation on conditioning rates 6. RF breakdown rates for different materials using a removable back plate7. Effect of magnetic fields on breakdown rates (important for muons and electron injectors)
