Study of Multiple Production in 4-geometry and Construction of the SPHERE Spectrometer. First-Line Experiments at the Nuclotron

Leaders:

A.M. Baldin
A. Malakhov

Scientific Programme:

Develoment of the SPHERE spectrometer and experiments on cumulative particle production and correlated phenomena. Search for manifestation of quark-gluon degrees of freedom in collisions of relativistic nuclei and phase transitions in nuclei (SPHERE, SLON, FASA) and exotic resonances. Study of nuclear multifragmentation processes and hyper- and --nuclei production (SLON, FASA, GIBS). The Nuclotron internal target experiments: two-arm EMCalorimeter, deuteron spin structure investigation (SPHERE). Cumulative particle production by tenzor polarized deuterons. Asymptotics in nuclear collisions, nucleon clusters. Development of data base for bubble chambers statistics. Detector development for relativistic heavy-ion experiments at the SPS (NA49), RHIC (PHENIX). Investigation of the 3He spin structure at RIKEN. Creation of some prototypes of front-end electronics for primary processing; some prototypes of a logic processor; interface and network modules to organize a multichannel multiprocessor data acquisition system. Some developments of LHE-oriented architectures to create the data acquisition system are proposed.
