Much experience has been acquired in building
wide band neutrino beams with a horn/reflector system, at CERN and elsewhere. Photographs
of the horn (top) and reflector (bottom) show the installation in the WANF beam for the
experiments CHORUS and NOMAD. These focusing devices were operated with 100/120 kA pulsed
current. The current connections can be seen in the foreground of each picture (upstream
end of the horn/reflector). For a description see "The West Area Neutrino Facility
for CHORUS and NOMAD experiments (94 - 97 operation)", G. Acquistapace,
V. Falaleev, J.M. Maugain, G. Olesen, S. Rangod,
J. Zaslavsky, CERN-ECP / 95-14, 31 July 1995.
