Performance of single-photon-counting PILATUS detector modules
PILATUS is a silicon hybrid pixel detector system, operating in single-photon-counting mode, that has been developed at the Paul Scherrer Institut for the needs of macromolecular crystallography at the Swiss Light Source (SLS). A calibrated PILATUS module has been characterized with monochromatic synchrotron radiation. The influence of charge sharing on the count rate and the overall energy res...
متن کاملPILATUS 2M A Detector for Small Angle X-ray Scattering
For the (coherent) small-angle X-ray scattering (SAXS) beamline X12SA of the Swiss Light Source at the Paul Scherrer Institut, a novel X-ray detector is built, the PILATUS 2M. Contributions in module fabrication, detector assembly, characterization and calibration are covered within the framework of this thesis. Furthermore, data analysis of a particular SAXS experiment demonstrating the perfor...
متن کاملCharacterization of an in-vacuum PILATUS 1M detector.
A dedicated in-vacuum X-ray detector based on the hybrid pixel PILATUS 1M detector has been installed at the four-crystal monochromator beamline of the PTB at the electron storage ring BESSY II in Berlin, Germany. Owing to its windowless operation, the detector can be used in the entire photon energy range of the beamline from 10 keV down to 1.75 keV for small-angle X-ray scattering (SAXS) expe...
متن کاملThe Cryoplanation of Mount Wellington
Present morphology of the Mt. Wellington summit area can be interpreted in terms of a system of cryoplanation, which operated during the Pleistocene, but bas now ceased. This involved the rapid frost shattering of exposed dolerite and the removal of this and previously weathered material by mass movement over slopes as low as 30 • Periglacial processes of land reduction were probably widespread...
متن کاملThe Photonic Railway
The Photonic Railway is proposed to overcome the limit of the current propulsion technology based on conventional rocketry for interstellar flight and to potentially open a new space era. The photonic railway, which is a permanent energy-efficient transportation structure based on the Beamed-Laser Propulsion (BLP) by Forward and the Photonic Laser Thruster (PLT) by the author, is proposed to en...
