The H1 detector started taking data at the electron-proton collider HE
RA in the beginning of 1992. In HERA 30 GeV electrons collide with 820
GeV protons giving a strong boost of the centre-of-mass system in the
direction of the proton, also called the forward region. For the dete
ction of high momentum muons in this region a muon spectrometer has be
en constructed, consisting of six drift chamber planes, three either s
ide of a toroidal magnet. A first brief description of the system and
its main parameters as well as the principles for track reconstruction
and T-O determination is given.
