Anything over eight feet tall, six feet wide and weighing over 20 tons might be expected to have a healthy appetite. But no traditional foods are ingested by this behemoth. For the BigBite magnet, the nourishment of choice is subatomic particles, and lots of them. The BigBite spectrometer, which consists of the magnet along with its detectors, will be able to discern scattered particles over a range of energies and angles far greater than can be obtained with the other spectrometers used in Jefferson Labs Hall A.
BigBite is the latest addition to the Department of Energys Jefferson Lab family of particle detectors. It comes via the Netherlands National Institute for Nuclear and High Energy Physics, NIKHEF, in Amsterdam which commissioned the magnets construction by Russian scientists in 1994. When the NIKHEF accelerator ceased operations in 1999, the institute sold the magnet to Jefferson Lab. The magnet was stored until, with the approval of a trio of Hall A experiments, researchers began refurbishing the magnet and building the associated particle detectors.
"BigBite will be able to work with the Hall A high resolution spectrometers or stand alone," says Douglas Higinbotham, the Hall A staff scientist who is coordinating the BigBite project. "There are three upcoming experiments that will definitely put BigBite through its paces. Four other experiments, proposed but not yet approved by the Labs program advisory committee, also wish to use BigBite."

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
