The COMPASS experiment — research on the spin structure of the nucleon

Project coordinator
prof. Jan Paweł Nassalski, Ph.D., D.Sc., Institute of Nuclear Problems, Świerk.

Partners
Institute of Nuclear Problems, Świerk, Warsaw University.

Aim of project
The project is part of long-term collaboration between the Institute of Radioelectronics and the international high-energy physics experiment COMPASS (Na58) at CERN (Geneva). Within the framework of a new program, the team from the Institute of Radioelectronics is responsible (together with partner teams) for the design of new methods of experimental data analysis, including applications of “soft computing” methods (neural networks, genetic algorithms etc.). The Institute is also involved in preparations of hardware upgrade of the COMPASS experiment for the new physical program foreseen for years 2008–2012.

Expected results
The purpose of the project is to develop software tools for the COMPASS experiment, allowing processing of data recorded in the experiment, particularly classification of types of interactions, estimation of parameters of these interactions and estimation of parameters of particle tracks. Once developed, the tools will be contributed to the collaboration. Also, a method and equipment for precise time-of-fl ight measurements in the Recoil Proton Detector (RPD) will be developed. RPD is one of the detectors necessary in order to meet goals of the 2008–2012 physics program.
