TRIGA Mainz reaches world record of 20,000 pulses in 50 years

12.10.2015

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.


Pulse operation with the characteristic blue Cherenkov radiation at TRIGA Mainz

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.

Im Focus: Stellar cartography

The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.

A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...

Im Focus: Heading towards a tsunami of light

Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.

"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...

Im Focus: Revealing the secret of the vacuum for the first time

New research group at the University of Jena combines theory and experiment to demonstrate for the first time certain physical processes in a quantum vacuum

For most people, a vacuum is an empty space. Quantum physics, on the other hand, assumes that even in this lowest-energy state, particles and antiparticles...

Im Focus: Sussex scientists one step closer to a clock that could replace GPS and Galileo

Physicists in the EPic Lab at University of Sussex make crucial development in global race to develop a portable atomic clock

Scientists in the Emergent Photonics Lab (EPic Lab) at the University of Sussex have made a breakthrough to a crucial element of an atomic clock - devices...

A new way to sense earthquakes could help improve early warning systems

Every year earthquakes worldwide claim hundreds or even thousands of lives. Forewarning allows people to head for safety and a matter of seconds could spell...
