| Research Abstract |
An electron-positron collider, VEPP-2000, aims at achieving a maximum luminosity of 2 x 10^<32>cm^<-2>s^<-1> up at 1 GeV per beam, by having round beam collisions between electrons and positrons. Data of hadroninc production by electron-positron collision between 1.4 and 2.0 cms energies are relatively scarce ; if this VEPP-2000 can achieve its design luminosity, experiments using VEPP-2000 will make it possible to understand fundamental processes and contribute much to the advancement of high-energy physics.
Round-beam collisions are essentially in one dimension due to their symmetry, and it can be expected that this 1-dimensional feature makes non-linear effect at beam-beam collision substantially weak. Computer simulation done by BINP-KEK collaboration really shows that VEPP-2000 machine will reach its luminosity goal by careful and fine tuning of its operation points.
Due to the limitation of available area that houses VEPP-2000, magnets should have high magnetic field. Especially, this machine needs to have two pairs of 13 tesla superconducting solenoid magnets, which are essential to create round beams.
The construction of VEPP-2000 has been completed in spring of 2007 and its commissioning has started. In a few years it will produce much physics results.
