The new devices, known as non-scaling fixed field alternating gradient accelerators – or ns-FFAG accelerators for short – will be smaller, simpler and significantly cheaper than their synchrotron and cyclotron counterparts. It is therefore expected that they will have a major impact as next generation hospital-based clinical accelerators for proton and carbon ion beam treatment of cancer.
Although no ns-FFAG accelerator has ever been constructed, BASROC believes that its research project, entitled CONFORM, will move rapidly from conceptual design to construction of a model electron accelerator (EMMA) which will be located at the CCLRC’s Daresbury Laboratory. The experience gained in the development and operation of EMMA will inform the design and eventual construction of a prototype proton/carbon ion ns-FFAG accelerator for medical applications (PAMELA).
In addition, an extensive parallel R&D programme will evaluate the potential of ns-FFAG accelerators as proton drivers for applications in scientific and technological fields as diverse as energy and environment (eg accelerator driven sub critical reactors, waste transmutation), materials research (eg advanced neutron and muon sources for studies of the structure and dynamics of materials), and fundamental physics (eg the neutrino factory).Professor Roger Barlow of Manchester University, Project Leader of CONFORM, says
Professor Bleddyn Jones, Consultant in Clinical Oncology & Applied Radiobiology University Hospital Birmingham comments “I anticipate that the flexibility and cost-effectiveness of the ns-FFAG accelerators will ultimately make particle radiotherapy more accessible within the UK, with considerable benefits in the reduction of radiation side effects, improved quality of life and prospects of cure in a wide variety of cancers.”
Professor Bob Cywinski from the University of Leeds comments “CONFORM will revolutionise accelerator science. We can envisage powerful but compact accelerators that are fully optimised for a single application. This is a significant change from conventional philosophy in which single large accelerators are generally built for several applications – a situation in which everyone compromises.”
Dr David Wilcox of the High Power RF Faraday Partnership and Chairman of the BASROC Board, says “CONFORM will provide a real focus for advanced accelerator technology and manufacturing in the UK. The resulting development of industrial expertise will enable the UK to secure a competitive edge in the provision of accelerator components for major international projects.”
CONFORM funding will commence in March 2007 and the new accelerator should start operation within 3 years.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
