TL;DR: The real-time dehydrogenation of MgH(2), a potential hydrogen storage compound, is investigated along with ultrafast high-throughput measurements to determine the crystallite quality of different samples of the metastable carbonate phase vaterite precipitated and stabilized in the presence of amino acid molecules in a biomimetic synthesis process.
Journal ArticleDOI
Merlin: a fast versatile readout system for Medipix3
TL;DR: The Merlin system as mentioned in this paper is based on a National Instruments PXI/FlexRIO system running a Xilinx Virtex5 FPGA and is capable of recording Medipix3 256 by 256 by 12 bit data frames at over 1 kHz in bursts of 1200 frames and running at over 100 Hz continuously to disk or over a TCP/IP link.

TL;DR: PERCIVAL as mentioned in this paper is a monolithic active pixel sensor (MAPS) based on CMOS technology, which can operate at frame rates up to 120 Hz and use multiple gains within its 27 μm pixels to measure (e.g. at 500 eV) 1 to 105 simultaneously arriving photons.
Journal ArticleDOI
EXCALIBUR: a small-pixel photon counting area detector for coherent X-ray diffraction - Front-end design, fabrication and characterisation
J. Marchal,I. Horswell,B. Willis,R. Plackett,E.N. Gimenez,J. Spiers,D Ballard,P. Booker,J. Thompson,P. Gibbons,S. Burge,T. Nicholls,J. Lipp,Nicola Tartoni +13 more
TL;DR: In this article, the authors describe the design, fabrication and characterisation of the MEDIPIX3-based modules composing the EXCALIBUR detector, which is under development for the X-ray Coherence and Imaging Beamline I13 of the Diamond Light Source.
Proceedings ArticleDOI
