Gaseous Electronics Conference (GEC)

It is one of the world's largest plasma conferences and is normally only held in convention centers or hotels. In Bochum, the Gaseous Electronics Conference will be held for the first time on the campus of a university.

The organizers of this year's Gaseous Electronics Conference, or GEC for short, are expecting around 450 international participants. The 69th edition, which will take place from October 10 to 14, 2016 at the Ruhr University Bochum (RUB), is thus expected to be the largest GEC ever.

The logistical and planning challenge includes, for example, 64 invited and 222 submitted talks, 262 poster contributions, a conference dinner at the Henrichshütte in Hattingen, a show at the Planetarium Bochum, laboratory tours at the RUB, a concert at the Audimax, a visit to the Botanical Garden, and an accompanying industrial exhibition with more than 20 companies.
Not in the USA for the fourth time only.

The organizer is the American Physical Society (APS). The meeting is organized locally by the Research Department "Plasmas with Complex Interactions" at RUB, in particular by Prof. Dr. Uwe Czarnetzki and his team.

"For only the fourth time in its nearly 70-year history, the meeting has not been held in the USA," explains Czarnetzki. "And for the first time ever, the meeting venue is the campus of a university. We are proud to have brought the GEC to Bochum." Last year, experts in plasma physics and technology met at the Honolulu Convention Center in Hawaii.
Plasmas are extremely versatile

In terms of content, the focus is on so-called low-temperature plasmas and the associated atomic and molecular physics. These are partially ionized - electrically charged - gases. They are characterized by high conductivity. They also exhibit unique chemistry and interaction with surfaces.

Their applications are broad, ranging from lighting to cancer treatment. Low-temperature plasmas can be used to coat, activate and clean surfaces, produce gas lasers and semiconductor devices, or disinfect medical equipment. They are also used in wound healing.

Broad and well positioned: Plasma research in Bochum

"Research and development are often interdisciplinary and primarily encompass physics, electrical engineering, chemistry - and more recently biology and medicine," like this. The Bochum Research Department Plasmas with Complex Interactions is correspondingly broadly positioned.

"The RUB has long been one of the world's strongest research universities in the field of plasma physics and technology and therefore enjoys an excellent international reputation," says Czarnetzki. Scientists from various faculties cooperate across disciplines in the Plasma research focus: a total of 23 chairs and research groups with more than 300 employees from physics and astronomy, electrical engineering, chemistry, biology and mechanical engineering.

Prof. Achim von Keudell ist Chair der GRC 2016

Die Gordon Research Conferences zählen zu den renommiertesten Konferenzen überhaupt. Mit der Verpflichtung der Vortragenden über aktuelle und unpublizierte Arbeiten zu sprechen und der Verpflichtung der  Teilnehmer diese Informationen vertraulich zu behandeln, zählt diese Konferenzreihe zu den spannendsten und interessantesten überhaupt. Nirgendwo sonst bekommt man mehr Einblicke in die aktuelle Entwicklung der Plasmaphysik und hat zusätzlich noch die Gelgenheit in entspannter Atmosphäre mit hochkarätigen Experten zu diskutieren.

Als Chair der GRC 2016 „Plasma with Complex Interations-Exploiting the Non-Equilibrium“ war Prof. Achim von Keudell maßgeblich an Organisation und Programmgestaltung beteiligt. Eine kleine EPII Delegation bestehend aus DoktorandInnen und einem Postdoc war ebenfalls vor Ort und konnte von dieser außergewöhlichen Konferenz profitieren.

Seventh International Conference on Fundamentals and Industrial Applications of HIPIMS 2016

High Power Impulse Magnetron Sputtering (HiPIMS) ist ein junges und vielversprechendes Verfahren um Dünnschichtsysteme mit hervorragenden Eigenschaften zu produzieren. Abgesehen vom praktischen Nutzen weisen diese Plasmen interessante physikalische Eigenschaften wie anomalen Teilchentransport und Strukturbildung auf, die noch immer nicht im Detail verstanden sind. Die Erforschung von HiPIMS Plasmen nimmt am Lehrstuhl EPII daher einen großen Stellenwert ein. Im Moment arbeiten drei Postdocs, zwei PhD Studierende und einige BA und MA Studierende an vier Experimente um mehr Einblick in diese interessanten Plasmen zu bekommen. Bei dieser Konferenz hatten die Mitarbeiter von EPII die Gelegenheit ihre Ergebnisse zu präsentieren und einen guten Austausch mit internationalen Experten. Die nächste HiPIMS Konferenz findet in Braunschweig 2017 statt.

The LAPD17 Symposium is the continuation of a biennial series that began at Kyushu University in 1983. It brings together physicists and chemists in diverse areas of laser-based plasma diagnostics including the physics of nuclear fusion, laser physics and low-temperature plasma chemistry and physics. The symposium aims to promote cross-vertilization of these fields via fruitful discussion, and covers all diagnostics using electromagnetic waves (lasers and microwaves) applied to fusion plasmas, industrial process plasmas, environmental plasmas, plasmas for medical applications, atmospheric plasmas, plasmas in liquids and other plasma applications. Topics on hardware developments related to laser-aided plasma diagnostics are also welcome.

DPG Spring Meeting Plasma Physics & Short Time Physics 2015

INTERNATIONAL WORKSHOP "COSMIC RAY ANISOTROPIES"

This interdisciplinary workshop will give a synoptic overview of the cosmic ray anisotropy observations by the large area telescopes as IceCube, Milagro, the Tibet airshower array among others, and those observed by spacecraft especially by the Voyager and Pamela spacecraft and the AMS instrument, as well as the theory and modeling efforts including that of the large scale heliosphere. The anisotropies in the cosmic ray flux appear from the high energy range (TeV) to low energy range (keV to MeV) that is in the propagation of galactic cosmic rays to the propagation of solar energetic particles as well as that of Jovian electrons. Recent Voyager observations also suggest that the low energy flux at the heliopause is anisotropic.
To describe the anisotropic transport a couple of models are discussed in literature. In the inner heliosphere focussed transport theories are used, which are solved numerically with the help of the equivalent stochastic differential equations. In the heliotail, for the high energy, the gyroradius is of the order of the cylindric diameter of the tail and thus one has to use the full orbit theory.
In addition all the transport models need as input the state of the local plasma enviroment. The latter is provided by large scale magnetohydrodynamic models.
Finallly, the transport of cosmic rays depends on the diffusion tensor, which is affected by the local magnetic field fluctuations and its turbulence. The acceleration or deceleration depends on the local structure of the shock fronts.
The positron anisotropy observed by Pamela spacecraft and the AMS instrument onboard of the ISS are another aspect of anomalies in the cosmic ray spectra, and some aspects shall be discussed with the emphasis on anisotropic distribution functions.
The workshop takes place at Physikzentrum Bad Honnef, 26 - 30 Januar 2015.
