"We have recently published a paper on quick measurement of CTR scattering profile using a PILATUS-100K. We think the use of the PILATUS-100K was one of key reasons of our success. In this regard I thank all the people who have been involved in the development of the PILATUS detector. I think that PILATUS detector is the most wonderful detector which I have ever used."
Tadashi Matsushita, Professor Emeritus, Photon Factory, December 12th, 2011
"The crystallographers are ecstatic over the high speed and high quality of the Pilatus data."
Malcolm Capel, NE-CAT, November 28th, 2011
"For small angle X-ray scattering (SAXS) on proteins data recording a good signal to noise ratio is a necessity. The practical noise free recording of SAXS data with the PILATUS detectors permits reliable data analysis and more accurate shape model building, even in dilute protein solutions. This property of the detector in combination with the high dynamic range and the large active area makes the PILATUS to the detector of choice for SAXS solution scattering."
Manfred Roessle, EMBL Hamburg, Project Leader BioSAXS Beamline for PETRA-3, May 14th, 2012
"The Pilatus detector has completely transformed the way X-ray photons are being detected today at synchrotron radiation sources, such as Diamond. This is something we could only have dreamt of in the early days of synchrotron sciences."
Prof. Dr. Gerhard Materlik (CBE), CEO of Diamond Light Source, June 18th, 2012

Check the DECTRIS website regularly during 2014 to read further news about our activities and involvement in the International Year of Crystallography.
Dr. Ulrich Rücker and his team at the Jülich Centre for Neutron Science (JCNS) have successfully put an outstanding SAXS instrument into operation. GALAXI (the Gallium Anode Low Angle X-ray Instrument) is an X-ray beamline in the laboratory dedicated to serve the needs for GISAXS and high-resolution SAXS investigations. The beamline's advanced laboratory X-ray source (MetalJet from Bruker AXS) is perfectly matched by highest performance X-ray detectors from DECTRIS: a PILATUS 1M hybrid pixel detector for recording SAXS data and a MYTHEN 1K strip detector for simultaneously recording WAXS signals with excellent angular resolution. The single-photon-counting technology of these detectors offers noise-free detection with a dynamic range of above 1:1,000,000, which assures that the SAXS/WAXS signals with their high intensity range can be optimally captured.
Ulrich Rücker, project leader of GALAXI, made a well-considered choice about the detectors for his beamline: "For our instrument, the PILATUS and MYTHEN detectors are superior to all other solutions due to their incredibly low background. This together with a careful design of the beamline enables us to measure very low GISAXS scattering signals, even if we need 30 minutes illumination time for a single picture."
A limited amount of time on the instrument is reserved for potential DECTRIS customers who would like to test the detectors on the beamline.

Diamond Light Source is one of the world's currently operating top synchrotron science facilities. Using the highly brilliant X-ray light produced by Diamond, scientists conduct research on important issues of our future. The findings of this research are highly sought after in a variety of scientific fields. They enable the development of nano- and high-performance materials such as more efficient catalysts and energy storage materials. Also, medical research and drug development is greatly driven forward by the knowledge gained at Diamond.
Particularly in the field of structure-based drug development, Diamond has developed over the last 10 years into one of the world's leading facilities. Recently, a team of virologists and structural biologists achieved a breakthrough in improving the vaccine against foot-and-mouth disease. This disease is still a major problem in livestock farming, often with disastrous economic consequences. The outbreak in England in 2001 caused the death of 7 million animals and economic losses of about £ 2 billion. Research at Diamond allowed scientists to determine the spatial structure of the foot-and-mouth disease virus particles at atomic resolution. Using this knowledge, a new type of vaccine could be developed. Atom by atom, the researchers changed the vaccine specifically and substantially improved its stability at high temperatures. The result is a safe and effective vaccine that can easily be produced and transported and has the potential to make the disease manageable worldwide. The powerful X-ray detectors from DECTRIS played an important role in this breakthrough. Thanks to their high speed and high image quality, a novel measurement method could be used that allows to acquire more and higher quality diffraction images of the very sensitive virus crystals.
Motivated by similar success and on request from Diamond, DECTRIS has developed over the past 18 months PILATUS3, the third generation of their PILATUS X-ray detectors. The first devices of the world's fastest X-ray cameras, acquiring up to 500 images per second, have now been installed at two synchrotron beamlines at Diamond in April. In early June, the detectors were officially inaugurated in a joint ceremony of Diamond and DECTRIS. After a timely delivery within a critical deadline, the first results obtained with PILATUS3 have sparked a lot of enthusiasm among Diamond's scientists. A complete dataset of several hundred images can now be acquired in less than a second. Only a few years ago such measurements lasted at least 10 minutes. More importantly, the measured data are of the highest quality. The structural biologists and pharmaceutical researchers will use PILATUS3 to develop further improved and highly efficient measurement protocols, enabling previously impossible experiments. The results obtained with these novel methods will continue to drive forward the development of drugs and vaccines.
PILATUS3 is DECTRIS' latest generation of ultimate performance Hybrid Pixel Detectors. This new series of X-ray detectors for the most demanding synchrotron applications was introduced in July 2012 at the International Conference on Synchrotron Radiation Instrumentation. The roadmap outlined to scientists and customers upon product launch scheduled first delivery of PILATUS3 2M and 6M for May and July 2013, respectively. With first delivery in April, DECTRIS is months ahead of the roadmap and meets critical deadlines of Diamond Light Source.
After less than two days of commissioning with our support team on site, the detectors are now running flawlessly at their maximum frame rates. The PILATUS3 6M with a maximum frame rate of 100 Hz will further facilitate outrunning of radiation damage at room temperature.
A recent publication in Nature shows how diffractive imaging methods can be generalized . The authors present a Ptychographic Imaging experiment with the PILATUS detector to demonstrate their findings. Simultaneous reconstruction of sample and wave front of the illuminating beam is achieved in this experiment, even using a not fully coherent X-ray beam. The PILATUS photon-counting pixel detector applied enables the precise measurement of the diffraction pattern around the very intense direct beam with high spatial resolution (PSF: 1 pixel). The new series of PILATUS3 detectors increases the measurement speed by offering even higher count rates up to 107 cps and frame rates of up to 500 Hz in diffractive imaging.
DECTRIS congratulates the authors to their research, which paves the way for a wider application of diffractive imaging techniques!

EIGER hybrid pixel detectors feature substantial progress towards faster frame rates and higher pixel density. This poses challenges in handling of large data rates and volumes for the detector system itself as well as the research facilities exploiting EIGER. To tackle these challenges, DECTRIS initiated a collaboration with The HDF Group as well as PSI and DESY, which face similar demands at synchrotrons and free electron lasers. The solutions to these challenges can not only be applied to EIGER, but are generally of great importance for sustained data acquisition at high rates.
Compression is an essential approach to handle large data volumes. However, at high data rates, compression has to be fast and data need to be compressed in parallel. To this end, DECTRIS and PSI financed development of an extension that allows to pass precompressed chunk data to the HDF5 library. Furthermore, development of a plug-in mechanism for dynamic loading of custom filters by The HDF Group was promoted by DESY. This allows to readily use suitable algorithms for fast compression and decompression with HDF5. The new extensions are scheduled for release with HDF5 1.8.11 in May 2013. Another challenge was the concurrent high-speed data writing and real-time experiment logging within the NeXus data format. The solution is a file architecture comprising a master file and a small number, depending on data volume, of data files. This approach enables simultaneous writing of experiment data and metadata. Extensions to the NeXus format allow logging of metadata specific to single photon counting detectors.
In their combination, the solutions and developments achieved in the collaboration between PSI, DESY, The HDF Group and DECTRIS pave the way to an efficient use of EIGER and any state-of-the-art detector delivering high data rates. Furthermore, the groundwork is laid for a multitude of applications with sustained high data rates at synchrotrons, free electron lasers and other research facilities that plan to use HDF5/NeXus as a framework for data management.
DECTRIS’ success in providing outstanding X-ray detectors to our customers is based on innovation and technological leadership, for which education is a prerequisite. However, education is also the basis for economic, political and social development. As such, education is an important step towards poverty reduction in every country. For this reason, DECTRIS donates 30’000 CHF for an education project in Tanzania implemented by HELVETAS Swiss Intercooperation, a Zurich based NGO for development cooperation.
Education and advanced training for teachers has been neglected in Tanzania for a long time, notably in the context of strained budgets. This is reflected by the poor performances of pupils in the country. The Tanzanian Teacher Union (TTU), in close collaboration with Helvetas, offers a comprehensive teacher training programme to improve the quality of primary education in English Language, Mathematics, Natural Science and Education for Sustainable Development. In addition, the programme makes adequate learning and teaching materials available to schools. Read HELVETAS’ acknowledgement here.
DECTRIS has developed a vacuum compatible version of the PILATUS 1M hybrid pixel detector in cooperation with the Physikalisch-Technische Bundesanstalt (PTB) in Berlin. The custom-designed detector has been installed at the Four-Crystal-Monochromator beamline of the PTB (FCM at BESSY II) in June 2012, and allows for Small Angle X-ray Scattering (SAXS) experiments to be carried out at photon energies below 3 keV with high dynamics and good spatial resolution.

Accurate rate correction factors are important for X-ray data acquired at high photon fluxes. A recently implemented Monte Carlo simulation is able to compute the correction factors taking into account the detector settings as well as the time structure of the X-ray beam at the synchrotron. The results of the simulation show good agreement with experimentally determined correction factors. Furthermore, it is shown that the use of fast detector settings in combination with an optimized time structure of the X-ray beam allows for measurements up to rates of 107 photons per second and pixel.
