Powerful neutron source at Mainz University is used by chemists and physicists from all over the world for basic research
The research reactor TRIGA at Johannes Gutenberg University Mainz (JGU) has reached a new milestone: after 50 years of consecutive operation, TRIGA Mainz achieved a total number of 20,000 pulses on October 1, 2015 – a world record.
On this day, the reactor was operated for test measurements of neutron detectors that will be used at the source for ultracold neutrons as part of the user facility at the PRISMA Cluster of Excellence at Mainz University.
TRIGA Mainz has a powerful neutron source, which is used by chemists and physicists from all over the world for fundamental research.
It can be operated in the steady-state mode with a maximum thermal power of 100 kilowatt or in the pulsed mode with a maximum thermal power of 250,000 kilowatt, released within 30 milliseconds. This produces the characteristic blue glow of underwater Cherenkov radiation, which was emitted during 20,000 pulses in the TRIGA reactor pool.
According to General Atomic, the company that developed the TRIGA reactor concept, no other TRIGA reactor was pulsed more often.
The International Atomic Energy Agency (IAEO) currently counts 35 running TRIGA reactors in 16 countries, 20 of these reactors can be pulsed.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
