Plasma waves are now well studied as sources of large accelerating fields for next generation particle accelerators. Using laser driven plasma waves, it is now possible to routinely accelerate particles to beyond GeV energies in the laboratory. Such beams are of great interest because they will radiate strongly and find common use in synchrotron and free-electron laser laboratories to produce high quality beams of radiation particularly x-rays. In this project, we will consider the use of the same structures used to accelerate particles in laser wakefield accelerators, as radiation sources. These structures have equally large focussing forces which can make relativistic electrons undulate as they traverse through the plasma in much the same way that they move in a magnetic undulator. The project will investigate the motion of charged particles in these high field plasma undulators through both experiment and simulation. We will particularly be interested in novel situations where the undulation of a laser wakefield beam can lead to narrow energy spread radiation (the undulator regime).Zulfikar to input

作为下一代粒子加速器的大加速场源，等离子体波已被广泛研究。利用激光驱动的等离子体波，现在可以在实验室中常规地将粒子加速到超过GeV能量。人们对这种光束非常感兴趣，因为它们将发出强烈的辐射，并在同步加速器和自由电子激光实验室中普遍使用，以产生高质量的辐射束，特别是X射线。在这个项目中，我们将考虑使用激光尾波场加速器中用于加速粒子的相同结构作为辐射源。这些结构具有同样大的聚焦力，可以使相对论电子在穿过等离子体时产生波动，其方式与它们在磁波荡器中的运动方式大致相同。该项目将通过实验和模拟来研究带电粒子在这些高场等离子体波荡器中的运动。我们将特别感兴趣的是新的情况，其中激光尾波场光束的起伏可以导致窄能散辐射(波动器区域)。Zulfikar到输入
