Another diploma thesis finished!
Stefan handed in his diploma thesis on “Real-Time Imaging of the annihilation Vertex Distributions for Antiprotons Stopping in Biological Targets”. As the name suggests, he investigated into a technique that measures the secondary particles created at the irradiation with antiprotons with a rather simple detector set-up, and uses the direction of flight information to reconstruct the annihilation vertex distribution in the irradiated tissue. Stefan verified the applicability of this technique in this thesis and compared experimental results to simulations he carried out.
Topical Workshop on ‘Longitudinal Beam Profile Measurements’
The exact determination of the time structure of ever shorter bunches in accelerators and light sources like the X-FEL, the ILC or CLIC is of high importance for the successful operation of these next-generation machines. It is also a key to the optimization of existing scientific infrastructures.
The Euroscience Open Forum (ESOF) is the biennial pan-European meeting dedicated to scientific research and innovation. At ESOF meetings leading scientists, researchers, young researchers, business people, entrepreneurs and innovators, policy makers, science and technology communicators and the general public from all over the world discuss new discoveries and debate the direction that research is taking in the sciences, humanities and social sciences.
QUASAR Contributions to BIW and IPAC
Most of the group’s present research activities were presented at this year’s Beam Instrumentation Workshop in Santa Fe, USA and the first International Particle Accelerator Conference that took place in Kyoto, Japan.
The research focus of the QUASAR Group lies on the development of key technologies and techniques for the Ultra-low energy Storage Ring (USR). This novel electrostatic storage ring will allow, for the first time, to realize kinematically complete collision studies between low energy antiprotons and various gas targets. These experiments require shortest beam pulses in the range of 1-2 ns at lowest beam energies of only 20 keV.
Article on Halo Studies Published in JINST
A thorough understanding of halo formation and its possible control is
highly desirable for essentially all particle accelerators. Particles outside the beam core are not only lost for further experiments, they are also likely to hit the beam pipe, and activate this, as well as accelerator and experimental components in close proximity, which makes work on the accelerator costly and time consuming. Well established techniques for transverse beam profile measurements of electron or high energy hadron beams are the observation of synchrotron radiation, optical transition radiation or the like. A particular challenge, however, is the detection of particles in the tail regions of the beam distribution in close proximity of the very intense beam core.
DITANET School on Complementary Skills - Liverpool, March 2010
Members of the Quasar Group involved in the DITANET project will take part in a Complementary Skills School at the University of Liverpool 15th-19th March 2010.
Marcel and Massimiliano both received a student grant to allow for their participation at this year's international particle accelerator conference (IPAC) - the largest conference of its kind in the world. Congratulations!
Low Energy, Low Intensity Beam Diagnostics
The first DITANET topical workshop took place on November, 24th and 25th in Hirschberg-Großsachsen near Heidelberg in Germany. It focused on the diagnostics of low energy and low intensity ion beams and brought together around 40 scientists and engineers from all over the world. Its particular aim was to join early stage researchers both from within the network and from the wider community with renowned experts to allow for establishing important contacts for their careers and for reviewing the status of the different R&D activities.
