The Advanced WAKefield Experiment (AWAKE) located at CERN is the only laboratory in the world to experiment with a proton-driven plasma accelerator. Plasma accelerators are a type of novel accelerator that has the potential to achieve very high accelerating gradients relative to conventional accelerators. This can lead to the build of more compact and affordable accelerators.An important part of the experiment is preserving the witness electron beam quality as it's accelerated. Therefore, it is necessary to be able to measure the beam characteristics such as the emittance and bunch length of the witness beam.One method in measuring the beam emittance is from betatron radiation emitted from the transverse oscillations of electrons. For measuring the bunch length we can use Cherenkov Diffraction Radiation (ChDR) emitted from charged particles passing by, in close vicinity, a medium faster than the phase velocity of light within the medium.The aim of the project is to contribute towards the design and build of betatron radiation as a non-invasive diagnostic tool to measure the witness beam emittance. Also, to continue and support the work on ChDR as a non-invasive diagnostic tool for bunch length, already designed and implemented into AWAKE by Dr. Can Davut.The project includes some time at CERN for at least 1 year and up to 2.5 years.

位于CERN的先进韦克菲尔德实验室（AWAKE）是世界上唯一一个使用质子驱动等离子体加速器进行实验的实验室。等离子体加速器是一种新型的加速器，相对于传统的加速器，它有可能实现非常高的加速梯度。实验的一个重要部分是在加速过程中保持见证电子束的质量。因此，有必要测量验证束的束流特性，如束流发射度和束团长度，测量束流发射度的一种方法是利用电子横向振荡产生的电子感应加速器辐射。为了测量束团长度，我们可以使用切伦科夫衍射辐射（ChDR），它是由带电粒子通过比介质中光的相速度更快的介质时发射的。该项目的目的是为设计和建造作为非侵入性诊断工具的电子感应加速器辐射来测量见证束发射度做出贡献。此外，继续和支持ChDR作为束长度的非侵入性诊断工具的工作，已经由Can Davut博士设计并实施到AWAKE中。该项目包括在CERN至少1年和长达2.5年的时间。
