Beam Diagnostics Challenges in Plasma Wakefield Acceleration | |
|
||
| The field of particle acceleration in plasma wakes has seen remarkable progress in recent years. These days, acceleration gradients in excess of 10 GV/m can be readily achieved using either ultra-short intense laser pulses or particle beams as wake drivers. With the advent of first multi-GeV electron beams from plasma and a general trend towards improved reproducibility, beam quality and control over the involved processes, plasma-acceleration techniques are starting to draw considerable interest in the traditional accelerator community. Part of this attention is based on the extreme beam properties obtainable with plasma, such as femtosecond duration and sub-micron normalized transverse emittance, which pose significant obstacles for beam characterization and require cutting-edge detection concepts. In addition, the conservation of these characteristics during beam transport is complicated by ~mm beta functions at the plasma exit in combination with correlated energy spreads typically on a percent level. This presentation will give an introduction into the field of plasma wakefield acceleration and provide an overview about challenges in diagnosing the generated beams. | ||

| WEPG51 | A Transverse Deflecting Structure for the Plasma Wakefield Accelerator Experiment, FLASHForward | 759 |
|

| The FLASHForward project at DESY is an innovative plasma-wakefield acceleration experiment, aiming to accelerate electron beams to GeV energies over a few centimeters of ionized gas. These accelerated beams must be of sufficient quality to be used in a free-electron laser; achievable only through rigorous analysis of both the drive- and accelerated-beam's longitudinal phase space. The pulse duration of these accelerated beams is typically in the few femtosecond range, and thus difficult to resolve with traditional diagnostic methods. In order to longitudinally resolve these very short bunch-lengths, it is necessary to utilize the properties of a transverse RF deflector (operating in the hybrid electromagnetic mode, HEM11), which provides a relation between longitudinal and transverse co-ordinates. It is proposed that this type of device, commonly known as a Transverse Deflecting Structure (TDS) due to its 'streaking' in the transverse plane, will be introduced to the FLASHForward beamline in order to perform these single-shot longitudinal phase space measurements. The initial investigations into the realization of this diagnostic tool are outlined. | ||
