Gamma rays will reach beyond the limits of light

23.10.2017

Researchers have discovered a new way to produce high energy photon beams. The new method makes it possible to produce these gamma rays in a highly efficient way, compared with today's technique. The obtained energy is a billion times higher than the energy of photons in visible light. These high intensity gamma rays significantly exceed all known limits, and pave the way towards new fundamental studies.

"When we exceed the limit of what is currently possible, we can see deeper into the basic elements of nature. We can dive into the deepest part of the atomic nuclei," says Arkady Gonoskov, researcher at the Department of Physics at Chalmers University of Technology.


Gamma rays are electromagnetic waves, just like visible light or X-rays, but with much higher energy. The most energetic gamma rays in the world could be created by the help of advanced laser physics. When the laser light is intense enough and all parameters are right, trapped particles (green) could efficiently convert the laser energy (surfaces in red, orange and yellow) into cascades of super-high energy photons (pink).

The results were recently published in the high impact journal Physical Review X. The new method is an outcome of a collaboration between Chalmers University of Technology in Sweden, Institute of Applied Physics and Lobachevsky University in Russia and University of Plymouth in the UK.

Physicists in different fields, as well as computer scientists, have managed to work out the numerical models and analytic estimates for simulating these ultra-strong gamma rays in a new and somehow unexpected way.

In normal cases, if you shoot a laser pulse at an object, all the particles scatter. But if the laser light is intense enough and all parameters are right, the researchers have found that the particles are instead trapped. They form a cloud where particles of matter and antimatter are created and start to behave in a very special, unusual way.

"The cloud of trapped particles efficiently converts the laser energy into cascades of high energy photons - a phenomena that is very fortunate. It's an amazing thing that the photons from this source can be of such high energy," says Mattias Marklund, professor at the Department of Physics at Chalmers.

The discovery is highly relevant for the future large scale laser facilities that are under development right now. The most intense light sources on earth will be produced at such research facilities - as big as football fields.

"Our concept is already part of the experimental program proposed for one such facility: Exawatt Center for Extreme Light Studies in Russia. We still don't know where these studies will lead us, but we know that there are yet things to be discovered within nuclear physics, for example new sources of energy. With fundamental studies, you can aim at something and end up discovering something completely different - which is more interesting and important," says Arkady Gonoskov.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

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...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

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.

Im Focus: Sharp images with flexible fibers

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.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
