Up to February 2004 I've been working in the ANKE collaboration, led by Prof. Hans Ströher (FZJ). The Experiment is an internal spectrometer at the Cooler Synchrotron COSY of the Institute for Nuclear Physics at the "Forschungszentrum Jülich". Together with Dr. Ralf Schleichert (FZJ) and others from the Vertex Group a silicon telescope (shown as a photo) has been designed, set up, and commissioned for the detection of slow protons and deuterons emerging from thin gas targets. This set-up is currently used for various purposes at ANKE (e.g. to determine the absolute luminosity or to measure the beam polarisation). |
| The main task, however, is the detection of the so-called "spectator" proton in quasi-free proton-neutron collisions on a deuterium cluster-jet target. This opens the possibility to measure inclusive reactions on the neutron at the ANKE facility. I have been working together with Dr. Sergey Barsov (PNPI) on the analysis of the data from the pn->dω reaction. The total cross sections extracted are plotted as red triangles in the figure. A publication has been prepared in close collaboration with Prof. Colin Wilkin (UCL) Eur. Phys. J. A 21, 521 (2004) (nucl-ex/0305031, pdf 327 kB). Another publication on the methodology has been published in Nucl. Instrum. Meth. A 530 (2004) 275: (science direct, pdf 350 kB). More detailed information may be taken from my diploma and PhD work (see papers). |
