Workshop on the scientific opportunities of a THz-FEL in Sweden

24 Nov 2014, 09:00 → 25 Nov 2014, 13:00 Europe/Stockholm

AlbaNova University Center Stockholm, Sweden

Mats Larsson

The main goal of the envisioned light source is to provide the Swedish research community with a first domestic THz FEL combined with an X-ray source. This will present a unique opportunity for time-resolved pump(THz)-probe(X-ray) measurements and make it an advanced instrument for multi-disciplinary research in physics, chemistry and bio-medicine. Electron bunches are accelerated in an RF linac to an energy of 10-20 MeV and compressed to a pulse length of 1-10 ps. These bunches are then used for generation of soft X-ray pulses, before they are sent through a bending arc and finally to the THz FEL oscillator.
