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. | |
