The H2 VLE beam

The H2 beam line on the North area of CERN is a multi purpose experimental particle beam of various particle types in the momentum range of 10-400(450) GeV/c. In 2003/2004 shutdown the beam line was modified in order to be able to produce and transport particle beams of momenta down to 1 GeV/c. Such particle beams with low momentum are demanded by the LHC experiment CMS in order to calibrate various sub-detector systems.

The layout is very similar to the VLE setup on the H8 beam line. Some performance results can be obtained from the VLE section of H8 like target configurations.

The final focus of the H2 VLE beam is the major difference to H8, caused by the installation of NA49, and results in a different spot size at the experimental zone H2A.
