The Gammatron beamline in E2 experimental hall at ELI Beamlines delivers ultrashort X-ray pulses with X-ray photon energies ranging from 1 keV up to 1 MeV with 10^8 photons in pulses of a few femtosecond duration. Moreover, these pulses can be precisely synchronized with the pump pulse which is split from the Gammatron main driving laser pulse. The Gammatron beamline enables two modes of operation:
1) The betatron source with the following features: broadband spectrum (1 – 100 keV), low divergence beam (< 20 mrad), small source size (~μm), short pulse duration (a few fs).
2) The Compton source with a broadband or quasi-monochromatic (at least 10% ΔE/E) spectrum (few tens of keV to few MeV). Beam divergence, source size, and pulse duration are comparable to the case of betatron.
Gammatron beamline is driven by the HAPLS L3 laser system, which is why there will be a single shot mode, followed by 3 Hz repetition rate mode and eventually 10 Hz repetition rate mode of operation depending on the development stage of the laser system.
