The Gibs Magnetic Spectrometer

The GIBS spectrometer is an experimental setup with a 2-m streamer chamber placed in a magnetic field as the main detector. The chamber provides for the detection of charged particles emitted from the internal target into the complete solid angle (4 pi geometry). The setup is used to study rare processes in a wide range of secondary-particle multiplicities.The spectrometer is described briefly, and its characteristics and the main methodological results concerned with the quality of experimental data are presented.
