The construction of the European XFEL in Hamburg, one of the most significant European research infrastructure has reached an important milestone: the 2.1 km long underground electron accelerator of the large facility has become operational. It consists of 98 resonators arranged serially along a distance of 1.7 km that, for the time being, accelerate electrons to an energy of 12 GeV (12 billion electron volts), a figure to be increased to 17.5 GeV during the next few months.
Over the last decade the Hungarian Association of Physics Students (Mafihe) has been organizing an annual winter school. This event acts like a break for the physics students after the tough examination period, exploring a stimulating part of physics or related scientific area. The topics are usually chosen to be on the edge of the mainstream education subjects and current enough to attract the young audience.
A research article published in Biomedical Optics Express in September 1, 2016 reached the first place in “Today's Top Downloads” for a few days after its online publishing. The paper has been published by the research group of Róbert Szipőcs, PhD of Wigner RCP and reports on a novel, Yb-fiber laser based, handheld 2PEF/SHG microscope imaging system. It is suitable for in vivo imaging of murine skin at an average power level as low as 5 mW at 200 kHz sampling rate.
