Development of Detector Systems for Internal and Fixed Target Heavy Ion Physics Experiments

Golubev, Pavel LU (2003) In Cosmic and Subatomic Physics Dissertation
Abstract
This thesis deals with intermediate energy heavy ion reactions with the particular aim to study the nuclear matter equation of state which defines the relation between statistical parameters of a fermionic system.



The development of equipment for two experiments, CA47 at The Svedberg Laboratory in Uppsala, Sweden and R16 at Kernfysisch Versneller Instituut (KVI), Groningen, The Netherlands, are described.



CA47 contains the CHICSi detector, a modular, ultra-high vacuum (UHV) compatible, multi-detector system, covering a solid angle of 3pi sr around the collision point. Together with two auxiliary detector systems CHICSi is placed at the cluster-jet target chamber of the CELSIUS storage ring. This thesis... (More)
This thesis deals with intermediate energy heavy ion reactions with the particular aim to study the nuclear matter equation of state which defines the relation between statistical parameters of a fermionic system.

CA47 contains the CHICSi detector, a modular, ultra-high vacuum (UHV) compatible, multi-detector system, covering a solid angle of 3pi sr around the collision point. Together with two auxiliary detector systems CHICSi is placed at the cluster-jet target chamber of the CELSIUS storage ring. This thesis gives a technical overview of the detector and the development carried out in order to achieve the desired detection performance. Some laboratory and in-beam tests are described and the analysis of the first experimental results is discussed.



The nuclear intensity interferometry experiment (R16) was performed in a dedicated beam-line of the AGOR superconducting cyclotron. Small-angle two-particle correlations were measured for the E/A = 61 MeV 36Ar + 27Al, 112Sn, 124Sn reactions, together with singles spectra. The experimental energy distributions of neutrons and light charged particles for the 36Ar + 27Al reaction have been analyzed with a Maxwellian multi-source prescription. These results, together with correlation function data, are used to extract information on the size of the emitting sources and their time evolution. (Less)
