Picosecond Photochemistry Studied with X-Ray Absorption Spectroscopy, using an X-Ray Streak Camera
place:ANKA seminar room, 1st floor, building 348
Affiliation:Advanced Photon Source, USA

Inviting person:Anton Plech, KIT-ANKA
Speaker:Bernhard Adams
Time:11:00 a.m.

Abstract:

The x-ray streak camera at the Advanced Photon Source (APS) is a fast detector that is capable of 1.5 to 2 ps time resolution. It is being used for x-ray spectroscopy and diffraction experiments in the laser pump, x-ray probe technique at photon energies from about 4.5 to 13 keV. The streak camera now has been in operation for several years.
 
The talk will present some experimental data on liquid-phase, time-resolved x-ray spectroscopy on iron compounds, as well as some diffraction experiments. There will also be a detailed discussion on how the streak camera is integrated into the beamline 7-ID of the APS, of some special focusing optics developed for the streak camera, and the use of microwave power amplifiers for generating the deflection voltage ramp to permit operation at repetition rates up to 88 MHz.
