Photoelectron spectrometer assembled in the dedicated vacuum chamber. (a) In the interaction region, EuXFEL pulses ionize the effusive gas target which is injected via a capillary. (b) 16 electron TOF drift-tubes provides polar angular resolution. (c) Each detector is mounted on a separate flange with feedthroughs for high voltage and signal readout. (d) Drift-tube with shield partially disassembled to display the four segments [A B C D]. |
