Life of a Photon in X-ray Spectroscopy

Uhlig, Jens LU (2011)
Abstract
This thesis summarizes the experimental work in which an ultrafast
X-ray laser plasma source was combined with various
scalable direct detection schemes to test a novel approach for
lab-based time-resolved X-ray absorption spectroscopy. A laser
plasma source based on a water jet target was built and commissioned.
X-ray and electron emissions of this source were characterized
with various direct detection schemes. The procedures
for spectral retrieval with direct detection CCD’s were optimized
with regard to the laser plasma source. The novel approach of using
a single photon measuring cryogenic microcalorimeter array
as a high-resolution (DE/E 2000 @ 6 keV) energy-dispersive
detector was... (More)

a single photon measuring cryogenic microcalorimeter array
as a high-resolution (DE/E 2000 @ 6 keV) energy-dispersive
detector was investigated. The potentially very high quantum
efficiency, large detection angle and straightforward scalability
make this device an interesting photon analyzer for low photon
yield experiments. In this thesis a prototype version of this detector
was built (in cooperation), implemented and commissioned
into the laser plasma setup. With this combination of a lab-based
broad-band source and the free standing microcalorimeter spectrometer
high resolution X-ray absorption spectra in transmission
mode were achieved. The thesis presents the first hard X-ray
absorption fine structure (XAFS) spectrum taken with this novel
approach and discusses further improvements and applications. (Less)
