A forced convection target system Is being developed for use at 'ne Clinton P. Anderson Meson Physics Facility (LAMPF) which will produce neutrons by bombarding liquid deuterium with a proton beam via the process p + d -» -n + 2p. The work described herein discusses the design and operating characteristics of a prototype unit designed to operate with a heat input of 200 watts. Data are presented on the operating characteristics of the unit using liquid hydrogen with heat disposition from both electrical heaters and from an electron beam of 25 MeV which has a time structure and intensity similar to that of LAMPF. Electron beam energy depositions of 25 W/cm were achieved^ Using data obtained on these tests a final target system has been designed and will be briefly * discussed.
