Abstract

The Nuclotron-based Ion Collider fAcility (NICA) is a new accelerator complex being constructed at JINR aimed to provide collider experiments with heavy ions up to uranium at maximum energy (center of mass) equal to √s ~11 GeV/u. It includes new 6.2 MeV/u linac, 440 MeV/u booster, upgraded SC synchrotron Nuclotron and collider consisting of two SC rings, which provide average luminosity of 10²⁷cm^-2∙s^-1. The new facility will allow also an effective acceleration of light ions to the Nuclotron maximum energy and an increase of intensity of polarized deuteron beams up to the level above 10¹⁰ particles/cycle. Accelerator complex NICA is being built on the experience and technological developments at the Nuclotron facility and incorporates new technological concepts. The scheme of the facility, its operation scenario and beam dynamics are presented in the report.

Abstract

The problem of focusing of intense heavy-ion beams is an important issue for investigating high energy densities in matter. Application of a plasma lens to this area of research has a number of essential advantages in comparison with the traditional system on the basis of quadruple lenses. At ITEP the plasma lens has been designed and installed into the exit channel of the TWAC accelerator complex. The description of the plasma lens and the results of the first experiments with this lens are reported.
