06.05.2014: Stopping power app available for Android devices

An electronic stopping power app for android was programmed by Casper Christensen in new collaboration between the Department of Physics and Astronomy and the Aarhus School of Engineering.

This app provides electronic stopping power data of fast ions in a wide range of targets. It is based on the open source libdEdx library, which is available on

The app features access to ICRU49 and ICRU73 tables, as well as MSTAR and an implemenation of the Bethe equation with low energy corrections.

31.01.2014: LET-painting increases TCP in hypoxic tumours

We have published a new paper in collaboration with GSI, where we deomstrate that a technique which we call LET-painting can be used in order to overcome tumour hypoxia.

21.11.2012: Release of a Demo verison of SHIELD-HIT12A

SHIELD-HIT12A is a Monte Carlo particle transport code capable of transporting heavy ions through arbitrary media. A free demo version where the random seed and statistics are fixed to 10.000 particles can be downloaded from the project development page. There are builds for Linux and Windows systems (32- and 64 bit). It is a beta-release, but we would like to bring this demo version to a broader community, and thereby hopefully also fix some more bugs before we release the full version.

15.11.2011: Direct Access to Stopping Power Data via the Web Application dEdx by APTG

The software library libdEdx, developed by APTG, was now also pushed to the web with the release of the frontend called dEdx []. dEdx provides stopping data from different sources such as ICRU, MSTAR, and a Bethe-Bloch Formula. At the moment, it is possible to choose from a variety of over 270 target media. And a calculation can be done with two mouse clicks!

03.10.2011: Aarhus applied for the Danish National Center for Particle Radiotherapy

A strong and international research environment at Aarhus University and Danmark's best cancer treatment at Aarhus University Hospital let Aarhus appear as the best place for the Danish National Center for Particle Radiotherapy. The application for the center has just been submitted to the Danish Ministry of Health. Additional information (in Danish) can be found here.

26.05.2011: Particle therapy center in Denmark

The Danish government agreed on a future health plan. The establishment of a center for particle therapy is a cornerstone of this plan. In general, it is intended to increase the annual expenses for the health sector by 1 1/2 to 2 billion DKK.  More details on the health plan and a fact sheet can be found in a press release (in Danish) by the Danish Ministry of Finance.

10.05.2011: Niels Bassler and Jørgen Petersen have been awarded the Professor Carl Krebs Birthday Grant 2011

The grant is awarded in special recognition of the pioneer efforts and research in particle therapy undertaken by the two physicists. A full article about the laureates and the relevance of their research in particle therapy in view of the current future plans of Aarhus University can be found here (Danish) or as a translation (English).

04.05.2011: APTG experiment in national German TV

A report about our antiproton cell experiments at CERN was broadcast by the national German TV channel ZDF. The full broadcast with the title "Abenteur Wissen: Dunkle Kräfte" (Adventure Knowledge: Dark Forces) is available as download (in German).



09.03.11: National Center for Particle Therapy at Aarhus University

Lauritz B. Holm-Nielsen, rector of Aarhus University, announced that a National Center for Particle Therapy should be established at the Aarhus University as one of four interdisciplinary centers. The statement was part of the official presentation (available as stream [min ~0:39], see also slide 26) of the future plan for the development of Aarhus University as decided by the university's management the day before. A short write-up can be found here.
