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