Figure 1
Simplified diagram of the FLASH timing pattern. The RF accelerating pulses (green line) have a repetition rate of 10 Hz and are split into two flattop regions for the FLASH1 (blue bars) and FLASH2 (red bars) bunch trains. The number of bunches and their repetition rate, at maximum 1.0 MHz, can be adjusted independently. A kicker-septum system (purple line) is used to deflect the FLASH2 bunch train into the FLASH2 FEL beamline. |
