Abstract
A time resolved setup combining sub-2fs UV pump pulses with attosecond XUV probe pulses is presented. This scheme will allow the UV photo-induced electron dynamics in bio-chemically relevant molecules to be investigated with unprecedented time resolution.

The role of the UV activated electron dynamics in the photochemistry of this complex molecule is still not known, the lack of a technology for the generation of few-fs UV pulses has limited the investigation of the UV photo-induced processes in bio-chemically relevant molecules to the time scale above tens of femtoseconds, mostly addressing the nuclear dynamics [3]
The beamline is seeded by 5 fs near infrared (NIR) pulses with 2 mJ energy, 1kHz repetition rate and a controlled carrier-envelope phase (CEP) with a residual error of 200 mrad [7]
Summary
A time resolved setup combining sub-2fs UV pump pulses with attosecond XUV probe pulses is presented. This scheme will allow the UV photo-induced electron dynamics in bio-chemically relevant molecules to be investigated with unprecedented time resolution.
