According to an embodiment of the present invention, a cryogenic fluid
delivery system includes a vessel containing a cryogenic fluid at a first
pressure and a first temperature, a first heat exchanger coupled to the
vessel for receiving the cryogenic fluid and cooling the cryogenic fluid
to a second temperature, a first pump coupled to the first heat exchanger
for pressurizing the cryogenic fluid to a second pressure, a second pump
for pressurizing the cryogenic fluid to a third pressure, a second heat
exchanger coupled to the second pump for cooling the cryogenic fluid to a
third temperature, and a nozzle coupled to the second heat exchanger for
delivering a jet of the cryogenic fluid toward a target.
