Setup / Configuration

The spectrometer consists of a strong permanent magnet and a long solenoid, which produces a 1 mT homogeneous magnetic field inside the flight tube. The combined magnetic field lines guide the electrons on a helical trajectory towards the microchannel plate detector. The electron kinetic energies are determined from the measured flight time with an expected energy resolution of about 0.3 eV.

A magnetic bottle time-of-flight spectrometer has been developed for ultrafast time-resolved photoelectron experiments of solvated systems. High-harmonic generation and a novel attosecond pump-probe setup are used to produce and control the delay between an UV pump and an XUV probe pulse. These pulses are then focused into the liquid jet. 
 We intend to observe the temporal evolution of electronic structure following photoexcitation and obtain information about excited state nuclear and electronic dynamics of solvated species. Initial work will concentrate on transition-metal complexes and the dynamical consequences of the Jahn-Teller effect. Later work will focus on the femtosecond and attosecond dynamics of solvated nanoparticles, starting with ZnO and TiO2.
