Images: IPNL | 17 May 2012For the first time, a large-scale calorimeter prototype for the ILC, fully equipped with embedded power-pulsed electronics, successfully passed a test beam at CERN a few weeks ago. A prototype of more than one cubic metre in size of CALICE’s Semi-Digital Hadronic Calorimeter successfully recorded and tracked 1 million particles from CERN’s SPS accelerator beam (muons and pions). Thanks to power pulsing, the detector front-end electronics was periodically disabled and enabled, following the beam cycle. Read more and view more photos about the test beam.

Image: H. Hayano | 29 March 2012At KEK's superconducting RF test facility, better known as STF, scientists are conducting beam tests of their photocathode RF gun towards beam operation of the accelerator for the Quantum Beam Project. On 22 March, scientists succeeded in the extraction of a 1-millisecond beam for a 162.5-megahertz bunch train. Pictured here is a signal from the beam position monitor (blue) and a laser gate signal (violet). Read more about the Quantum Beam Project in a future issue of ILC NewsLine.

Image: Kröller-Müller Museum | 22 March 2012DESY's synchrotron radiation source DORIS has helped settle a decades-old question of whether van Gogh painted the 1886 Still life with meadow flowers. Using macro scanning X-ray fluorescence spectroscopy, scientists were able to analyse the canvas's layers of paint with greater detail than had been possible previously. Earlier X-ray analyses had shown that a painter - suspected to be van Gogh - had painted a scene of two wrestlers on the canvas before painting the flower still life over it several months later. DESY's work revealed even more, in particular, the color palette the painter used for the two wrestlers and their relative state of dress. Both attributes helped authenticate the work as a van Gogh. A beam of particles (figuratively) painted a picture of greater detail. Read the DESY press release

Image: CERN/M. Lapka | 15 March 2012Young researchers analysing real high-energy collisions from the LHC at CERN. From 27 February to 24 March, about 8000 high school students in 31 countries come to one of about 120 nearby universities or research centres for one day in order to unravel the mysteries of particle physics. Lectures from active scientists give insight in topics and methods of basic research at the fundaments of matter and forces, enabling the students to perform measurements on real data from particle physics experiments themselves. At the end of each day, as in an international research collaboration, the participants join in a video conference for discussion and combination of their results.

Image: Dirk Noelle | 8 March 2012Visitors ramble where electrons will one day whizz: a large number of people working at DESY and the European XFEL were treated to a rare trip underground into the recently completed but still completely empty tunnel for the European XFEL. And empty tunnels make for good images. Read more about the European-XFEL tunnel

Images: Jefferson Lab | 23 February 2012Charles Reece, deputy director of Jefferson Lab’s Institute for Superconducting Radiofrequency Science and Technology, leads GDE Executive Committee members on a tour of the new facilities that will be available upon completion of the Technology and Engineering Development Facility, a $72 million structure that will keep the lab in the forefront of SRF developments. John Hogan, Jefferson Lab SRF Cryomodule Production Leader, shows GDE Executive Committee members the sixth C100 cryomodule (of ten) being produced at Jefferson Lab as part of the lab's 12 GeV CEBAF Upgrade Project. This cryomodule is at the cold-mass assembly stage and Hogan is discussing the integrated design of the components as they relate to overall cryomodule performance. Members of the GDE Executive Committee pause during a tour of Jefferson Lab's Institute for Superconducting Radiofrequency Science and Technology for a group photo between two C100 cryomodules being built for Jefferson Lab's 12 GeV Upgrade.
