Bremsstrahlung radiation in the deuteron-proton collision
50 S., 2004
Despite the fact that Bremsstrahlung radiation has been observed many years ago,
it is still the subject of interest of many theoretical and experimental groups. Due
to the high sensitivity of the NN → NNγ reaction to the nucleon - nucleon potential,
Bremsstrahlung radiation is used as a tool to investigate details of the nucleon - nucleon
interaction. Such investigations can be performed at the cooler synchrotron COSY in
the Research Centre Rilich, by dint of the COSY-11 detection system.
For the first time at the COSY-11 experiment signals from γ - quanta were observed in
the time - of - flight distribution of neutral particles measured with the neutral particle
detector.
In this thesis the results of the identification of Bremsstrahlung radiation emitted via
the dp → dpγ reaction in data taken with a proton target and a deuteron beam are
presented and discussed.
The time resolution of the neutral particle detector and its timing calibration are crucial
for the identification of the dp → dpγ reaction. Therefore, methods of determining the
relative timing between individual modules - constituting the neutron detector - and of
the general time offset with respect to the other detector components are described.
Furthermore the accuracy of the momentum determination of the registered neutron
which defines the precision of the event reconstruction was extracted from the data.
