The CERN Axion Solar Telescope (CAST): status and prospects
Abstract
The CAST experiment is being mounted at CERN. It will make use of a decommissioned LHC test magnet to look for solar axions through its conversion into photons inside the magnetic field. The magnet has a field of 9 Tesla and length of 10 m and is installed in a platform which allows to move it ~8 degrees vertically and ~40 degrees horizontally. According to these numbers we expect a sensitivity in axion-photon coupling ~5 x 10-11 GeV-1 for axion masses m < ~10-2 eV, and with a gas filled tube 10-10 GeV-1 for m < ~2 eV.
