Parallel Session 1: Technique Development 1
- Peter Kappen
The detector group of the Swiss Light Source (SLS) at the Paul
Scherrer Institut (PSI) in Switzerland has many years of experience
in the development of single photon counting systems like Pilatus,
Mythen and Eiger. Due to the startup of the european XFEL and
SwissFEL the focus of the SLS detector group moved from photon
counting to charge integrating detector systems. The charge
integrating...
The recent deployment of a Dectris 16M Eiger detector on MX2 has changed the ‘standard’ data collection protocol for CX work to a new shutterless 360° oscillation yielding 3600 frames in 36 seconds. This step change in sample and data throughput has led to challenges in user workflow and highlights that the biggest dead time during beamtime arises during manual sample handling with the need to...
The Powder Diffraction (PD) beamline at the Australian Synchrotron has operated its User program for 11 years with over 1200 proposals submitted and more than 650 experiments completed. These experiments and the collaborations with the beamline team have assisted the User Community in producing over 600 publications across a broad range of scientific fields. As the PD beamline ages, several...
X-ray fluorescence microscopy (XFM) can be used for elemental and chemical microanalysis across length scales ranging from millimeter to nanometer. XFM is ideally suited to quantitatively map trace elements within whole and sectioned plant, biological specimens such as tissue sections, environmental and soil samples. The high elemental sensitivity of X-ray fluorescence microprobes coupled...
With increased resolution and extra dimensional imaging, an increased radiation dose is delivered to the specimen. After some point, the integrity of the specimen will be compromised, and therefore so will the data. Here we present a method for assessing the radiation induced changes in the specimen, taking into account variations in noise and resolution between measurements. We apply this...
