Plasma wakefield acceleration is nowadays very attractive in terms of accelerating gradient, able to overcome conventional accelerators by orders of magnitude. However, this poses very demanding requirements on the accelerator stability to avoid large instabilities on the final beam energy. In this study we analyze the correlation between the driverwitness distance jitter (due to the radio-frequency timing-jitter) and the witness energy gain in a plasma wakefied accelerator stage. Experimental measurements are reported by using an electro-optical sampling diagnostics with which we correlate the distance between the driver and witness beams before the plasma accelerator stage. The results show a clear correlation due to such a distance jitter, highlighting the contribution coming from the radio-frequency (RF) compression.

Abstract

Plasma wakefield acceleration is nowadays very attractive in terms of accelerating gradient, able to overcome conventional accelerators by orders of magnitude. However, this poses very demanding requirements on the accelerator stability to avoid large instabilities on the final beam energy. In this study we analyze the correlation between the driverwitness distance jitter (due to the radio-frequency timing-jitter) and the witness energy gain in a plasma wakefied accelerator stage. Experimental measurements are reported by using an electro-optical sampling diagnostics with which we correlate the distance between the driver and witness beams before the plasma accelerator stage. The results show a clear correlation due to such a distance jitter, highlighting the contribution coming from the radio-frequency (RF) compression.
