A conceptual design is presented for a high power cupronickel pion production
target. It forms a circular band in a horizontal plane with approximate
dimensions of: 2.5 meters radius, 6 cm high and 0.6 cm thick. The target is
continuously rotated at 3 m/s to carry heat away from the production region to
a water cooling channel. Bunches of 16 GeV protons with total energies of 270
kJ and repetition rates of 15 Hz are incident tangentially to arc of the target
along the symmetry axis of a 20 Tesla solenoidal magnetic capture channel. The
mechanical layout and cooling setup are described. Results are presented from
realistic MARS Monte Carlo computer simulations of the pion yield and energy
deposition in the target. ANSYS finite element calculations are beginning to
give predictions for the resultant shock heating stresses.
