We propose to perform a proof-of-principle test of a target station suitable
for a Neutrino Factory or Muon Collider source using a 24-GeV proton beam incident on a target
consisting of a free mercury jet that is inside a 15-T capture solenoid magnet. This test
could be performed in the TT2A tunnel of the NTOF proton line (upstream of the spallation
target). The tests would require only ~100 fast-extracted pulses of full PS
intensity, delivered in a pulse-on-demand mode of operation over about 10 shifts. The main piece of
apparatus is the LN2-precooled, 15-T copper magnet with a 15-cm-diameter warm bore and total
volume slightly over 1 m3. The principle diagnostic is a high-speed optical camera. The
mercury jet is part of a closed mercury loop that includes an insert into the bore of the
magnet.
