摘要：

我们提出了一个多单元RF注入器的预期性能与热离子阴极或门控光电阴极操作。通过磁压缩和100 ~ 200 mm辐射的相干自发发射种子自由电子激光，系统产生了峰值电流为200 A、发射度为2 mm.mrad rms的完全聚束束。电子束团是几个自由电子激光桶长和相位锁定的RF，使该设备成为第二代等离子体加速实验的理想注射器。

英文摘要：

We present the anticipated performances of a multi-cell RF injector operated either with a thermoionic cathode or with a gated photo-cathode. By means of a magnetic compression and a Coherent Spontaneous Emission seeded FEL radiating at 100 to 200 mm, the system produces a beam fully bunched with a 200 A peak current at 2 mm.mrad rms emittance. The electron bunch is a few FEL buckets long and phase-locked to the RF so to make this device an ideal injector for second generation plasma acceleration experiments.

基于性能增强型EC-ITC RF枪的FEL喷油器物理设计

Physical design of FEL injector based on performance-enhanced EC-ITC RF gun

为满足高性能太赫兹自由电子激光（自由电子激光）的要求，提出了一种紧凑型自由电子激光注入器方案。采用热阴极代替结构复杂、成本高的光电阴极进行电子发射。采用增强型EC-ITC（External Cathode Independently Tunable Cells）射频电子枪提取微束团，有效束团电荷提高到~ 200 pC，同时基本消除了背轰击效应。设计了恒梯度加速器结构，将能量提高到~ 14 MeV，采用聚焦系统抑制发射度，维持束团状态。对自由电子激光注入器关键部件的物理设计和束流动力学进行了分析。利用MATLAB和Parmela软件进行了多脉冲下的仿真。结果表明，该方法可以稳定地获得连续的高亮度电子束团，同时具有较低的能散和发射度。

Demonstration of Planar Ultrananocrystalline Diamond Field Emission Source Operating in SRF Injector at 2 Kelvin

Reported here is the first demonstration of electron beam generation in an SRF TESLA 1.3 GHz gun equipped with field emission cathode when operated at 2 Kelvin. The cathode is submicron film of nitrogen-incorporated ultrananocrystalline diamond [(N)UNCD] deposited atop a Nb RRR300 cathode plug. The output current was measured to increase exponentially as a function of the cavity gradient. Our results demonstrate a feasible path toward simplified fully cryogenic SRF injector technology. One important finding is that the electron emitter made of (N)UNCD, a material long been known as a highly ef…

In-situ measurements of the intrinsic emittance of photocathodes for high brightness electron beams

The beam parameters of complete prototype of the bERLinPro injector that consisted of a lead cathode in an 1.6 cell superconducting cavity were measured. The measurements are discussed in chapter 2 and indicate that the beam emittance is governed by a multitude of contributions from the cathode and the injector. Cathodes for practical use must have a high enough QE to deliver the required current at moderate illumination intensities and be able to sustain the operation for several days. Alkali antimonides are good candidates for this purpose, as discussed in chapter 3.2. The preparation of suc…

FEbeam: Cavity and Electron Emission Data Conversion, Processing and Analysis. A Freeware Toolkit for RF Injectors

FEbeam is a compact field emission data processing interface with the capability to analyze the field emission cathode performance in an rf injector by extracting the field enhancement factor, local field, and effective emission area from the Fowler-Nordheim equations. It also has the capability of processing beam imaging micrographs using its sister software, FEpic. The current version of FEbeam was designed for the Argonne Cathode Teststand (ACT) of the Argonne Wakefield Accelerator facility switch yard. With slight modifications, FEbeam can work for any rf field emission injector. This soft…

Experiments On A Conduction Cooled Superconducting Radio Frequency Cavity With Field Emission Cathode

To achieve Ampere-class electron beam accelerators the pulse delivery rate need to be much higher than the typical photo injector repetition rate of the order of a few kilohertz. We propose here an injector which can, in principle, generate electron bunches at the same rate as the operating RF frequency. A conduction-cooled superconducting radio frequency (SRF) cavity operating in the CW mode and housing a field emission element at its region of high axial electric field can be a viable method of generating high repetition-rate electron bunches. In this paper, we report the development and exp…

Ampere-class Bright Field Emission Cathode Operated at 100 MV/m

High current bright sources are needed to power the next generation of compact rf and microwave systems. A major requirement is that such a source could be sustainably operated at high frequencies, well above 1 GHz, and high gradients, well above 100 MV/m. Field emission sources offer simplicity and scalability in a high frequency era of the injector design, but the output rf cycle charge and high gradient operation remain a great and largely unaddressed challenge. Here, a field emission cathode based on ultra-nano-crystalline diamond or UNCD, an efficient planar field emission material, was t…

Controlled density-downramp injection in a beam-driven plasma wakefield accelerator

This paper describes the utilization of beam-driven plasma wakefield acceleration to implement a high-quality plasma cathode via density-downramp injection in a short injector stage at the FLASHForward facility at DESY. Electron beams with charge of up to 105 pC and energy spread of a few percent were accelerated by a tunable effective accelerating field of up to 2.7 GV/m. The plasma cathode was operated drift-free with very high injection efficiency. Sources of jitter, the emittance and divergence of the resulting beam were investigated and modeled, as were strategies for performance improvem…

RF design of APEX2 two-cell continuous-wave normal conducting photoelectron gun cavity based on multi-objective genetic algorithm

High brightness, high repetition rate electron beams are key components for optimizing the performance of next generation scientific instruments, such as MHz-class X-ray Free Electron Laser (XFEL) and Ultra-fast Electron Diffraction/Microscopy (UED/UEM). In the Advanced Photo-injector EXperiment (APEX) at Berkeley Lab, a photoelectron gun based on a 185.7 MHz normal conducting re-entrant RF cavity, has been proven to be a feasible solution to provide high brightness, high repetition rate electron beam for both XFEL and UED/UEM. Based on the success of APEX, a new electron gun system, named APE…
