Abstract

HIRFL-CSR, the project that was proposed to upgrade the HIRFL facility, is a multifunctional Cooling Storage Ring (CSR) system, consisting of a main ring (CSRm) and an experimental ring (CSRe). The heavy ion beams from the HIRFL will be injected, accumulated, cooled and accelerated to high energy in the CSRm, then fast-extracted to produce radioactive ion beams (RIB), highly-charged stage ions, or slow-extracted to do experiment. The secondary beams will be accepted by CSRe and used for internal-target experiments of the high sensitive and high precision spectroscopy with cool beam. CSR project was started in end of 1999 and finish in the end of 2004. The period from beginning of 2000 to the summer of 2001 is the time for the building construction, fabrication design, prototype experiments. In this paper, the outline and status of the project will be reported. [ABSTRACT FROM AUTHOR]

Abstract

The commissioning of the cooler storage rings (CSR) was successful, and the facility provides new possibilities for atomic physics with highly charged ions. Bare carbon, argon ions, were successfully stored in the main ring CSRm, cooled by cold electron beam, and accelerated up to 1 GeV/u. Heavier ions as Xe44+ and Kr28+ were also successfully stored in the CSRs. Both of the rings are equipped with new generation of electron coolers which can provide different electron beam density distributions. Electron-ion interactions, high precision X-ray spectroscopy, complete kinematical measurements for relativistic ion-atom collisions will be performed at CSRs. Laser cooling of heavy ions are planned as well. The physics programs and the present status will be summarized. [ABSTRACT FROM AUTHOR]

Abstract

CSR, a new Cooler-Storage-Ring project, is the postacceleration system of the Heavy Ion Research Facility in Lanzhou (HIRFL). It consists of a main ring (CSRm) and an experimental ring (CSRe). From the HIRFL cyclotron system the heavy ions will be accumulated, cooled and accelerated in the CSRm, then extracted fast and injected into the CSRe for many internal-target experiments with electron cooling. The experimental ring (CSRe) will be operated with three lattice modes for different experiments. The details of the lattice for the two rings will be described in this paper. [ABSTRACT FROM AUTHOR]
