MOY02 | NICA Ion Coolider at JINR | 12 |
|
||
The Nuclotron-based Ion Collider fAcility (NICA) is under construction in JINR. The NICA goals are providing of colliding beams for studies of hot and dense strongly interacting baryonic matter and spin physics. The accelerator facility of collider NICA consists of following elements: acting Alvarez-type linac LU-20 of light ions at energy 5 MeV/u, constructed a new light ion linac of light ions at energy 7 MeV/n and protons at energy 13 MeV, new acting heavy ion linac HILAC with RFQ and IH DTL sections at energy 3.2 MeV/u, new acting superconducting booster synchrotron at energy up 600 MeV/u, acting superconducting synchrotron Nuclotron at gold ion energy 4.5 GeV/n and mounted two Collider storage rings with two interaction points. The status of acceleration complex NICA is under discussion. | ||

TUB02 | NICA Collider Magnetic Field Correction System | 41 |
|
||
The NICA Collider is a new superconducting facility that has two storage rings, each of about 503 m in circumference, which is under construction at the Joint Institute for Nuclear Research, Dubna, Russia. The influence of the fringe fields and misalignments of the lattice magnets, the field imperfections and natural chromaticity should be corrected by the magnetic field correction system. The layout and technical specification of the magnetic field correction system, the main parameters, arrangements and the field calculations and measurement results of the corrector magnets are presented. The results of dynamic aperture calculation at working energies are shown. | ||

Features of Reaching the Operating Vacuum in the Accelerators of the NICA Project | |
|
||
The heavy ion NICA collider has three types of the vacuum volumes: insulating vacuum volume of superconducting magnet lattice; the cold beam pipe inside SC-magnets with operating temperature from 4.2 K to 80 K; the warm beam volume at the room temperature inside the insertion and experimental regions with RF stations, beam cooling station, diagnostic equipment and etc. The vacuum requirements, design of three vacuum systems, problems and paths of their decision for achievement ultra-high vacuum are described. | ||
