Priority:1
Status: In-progress

Study of Multiple Production in 4-geometry.
Experiments at the Nuclotron

Leader:   A.I. Malakhov
Deputy: E.B. Plekhanov

Scientific Programme:
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 (FASA, PHENIX) and exotic resonances. Study of nuclear multifragmentation processes and hyper- and -nuclei production (FASA, GIBS).
The Nuclotron internal target experiments: research using the two-arm EMCalorimeter and deuteron spin structure investigation.
Cumulative particle production by tenzor polarized deuterons.
Asymptotics in nuclear collisions and nucleon clusters.
Development of the data base of the bubble chamber data.
Detector development for relativistic heavy-ion experiments at the SPS CERN (NA49), RHIC BNL (PHENIX).
Investigation of the 3He spin structure at RIKEN.
Construction of some prototypes of the front-end electronics for primary processing; some prototypes of the logic processor; interface and network modules to organize a multichannel multiprocessor data acquisition system. Some developments of VBLHE-oriented architectures to construct a data acquisition system.
Obtaining the data on heat generation, neutron multiplication, spectra, fission and radiation capture in the model uranium blanket and target-converter of the installation "Energy plus Transmutation". Studies of transmutation cross sections of radioactive nuclear wastes (iodine-129, neptunium-237 and plutonium-239). Study of fragmentation of light stable and radioactive nuclei in emulsions including irradiation of emulsion stacks with beams of secondary nuclei and data analysis.

Expected main results in 2006:
