Schematic of the RF-cavity based timing tool at FemtoMAX which was used as a reference in this study. The electron bunch interacts with a button antenna, which also acts as a beam position monitor. The laser is detected by a fast photodiode (Fast PD). The two signals are combined and excite an RF cavity resonance. The two signals are amplified and measured on the same oscilloscope channel using a 80 Gs s−1 oscilloscope. |
