kutatási eredmények (magyarul)
Az OTKA által támogatott kutatás két területre bontható. I. A BNL RHIC gyorsítójának PHENIX kísérletében a mérésekben és a kísérleti adatok analízisében való részvétel: Csoportunk a PHENIX kollaboráció tagjaként dolgozott, munkája beépült a PHENIX kísérlet közös eredményeibe. Néhány területen a csoport hozzájárulása különösen jelentős volt. Igy kiemelendő a jet-elnyomás jelenségének vizsgálata különböző energiájú nehézion ütközésekben illetve az elektreomágneses kaloriméterrel kapcsolatos szimulációs és kalibrációs tevékenység. II. Részvétel a CERN-i LHC CMS kísérletének építésében, ezen belül a barrel müon kamrák helyzetmeghatározó rendszerének fejlesztése és létrehozása: a pályázati időszak alatt megépítésre került a teljes rendszer, amely lehetővé teszi a CMS barrel müon spektrométerét alkotó 250 nagyméretű driftkamra helyzetének meghatározását szubmilliméteres pontossággal.
kutatási eredmények (angolul)
The research activity supported by the OTKA fund can be divided in two groups. I. Participation in the measurements and the physics analysis of the PHENIX experiment at the RHIC accelerator in BNL (USA): our group worked in close collaboration with other members of the experiment so its work was integrated in the common results of the whole collaboration. In some areas, however, the contribution was particularly significant. Two areas can be emphasized, the investigation of jet suppression in heavy ion collisions at different energies and the simulation and calibration of the electromagnetic calorimeter. II. Participation in the construction of the CMS experiment to be installed at the LHC accelerator (CERN, Switzerland), development and construction of the barrel muon position monitoring system: the full system has been completed during the period of the OTKA-support. It allowes us to determine the positions of 250 large-scale drift-chambers forming the barrel muon spectrometer with submillimeter accuracy.
