A magnetic-bottle
time-of-flight (MTOF) photoelectron spectroscopy (PES) apparatus is built up
in our lab. Figure shows a photo view of the MTOF-PES apparatus. It consists
of a laser vaporization cluster source, an orthogonal
acceleration/extraction reflectron time of flight (oaRETOF) mass
spectrometer, a mass gate, a momentum decelerator, and a MTOF electron
analyzer.

A view of our laboratory.
Our lab is equipped with 5 chambers (3 TOFMS and 2 LIF), eight Nd/YAG
lasers, an optical parametric oscillator / optical parametric amplifier
(OPO/OPA) system for IR output, an ArF excimer laser (193 nm), a tunable
femtosecond laser, two VUV laser (118 nm) cells, and an EUV laser (46.9
nm).

The TOFMS chamber is on
the right and on the left is an LIF chamber. For the TOFMS, a pulsed valve
is inserted into the chamber. The ablation laser and ionization laser enter
the chamber perpendicular to the valve axis.
