Particles from target E are extracted at an angle of with respect to the proton beam direction for the beam line which transports pions and muons of momenta ranging from 10 to 500 MeV/c. The channel can be operated in two regimes: The first mode offers high fluxes with low momentum resolution. The range of momenta is limited to 280 MeV/c. The second regime is a low acceptance mode with high momentum resolution up to 500 MeV/c. The characteristics of the beam line are listed in table ; figure is a sketch of the beam channel.
Table: Some characteristics of the Channel.
Figure: The Beam Line. This is the standard part of the channel. The continuation of the beam line displayed in figure 3.2 or figure 3.6, is adjustable according to the experiment.
