For magnetic confinement,this step is expected inone of the large tokamak experimental devices such as TFTR(USA),JET(EC),JT-60(Japan),or T-15(USSR).  Upgraded versions of the Novaglass laser(USA)and GEKKO(Japan)also appear to have a good chanceat this goal.  The light-ion beam facility“PBFA-II”is viewed as a\"dark horse\"candidate.  Recent physics parameters obtained in thesevarious experiments will be briefly reviewed in this presentation.  \nHowever,after breakeven is achieved,considerable time andeffort must still be expended to develop a usable power plant.  Thetime schedules envisioned by workers in the various countries involvedare fairly similar.(1-3)  For example,the European Community(EC)proposes to go from the physics studies in JET to an engineering testreactor(NET)which has a construction decision in 1991.  This isprojected to result in a demonstration reactor after 2015.  Plans forinertial confinement are currently centered on the development of a\"next-step\"target facility based on an advanced 5-megajoule laser onroughly the same time scale as NET。(5)  The facilities required forboth magnetic and inertial confinement will be large and expensive.Consequently,international cooperation is receiving strongconsideration for the next magnetic facility,namely ITER  \n(International Thermonuclear Experimental Reactor).  This projectwould be shared by the USA,EC,USSR,and JAPAN.  \nThe main program described above is focused on D-T devices.  Forburning advanced fuels such as D-3He however,alternate confinementconcepts with high(530%)plasma beta(magnetic confinement)(6)or aD-T seed ignited burn(7)(inertial confinement)appear necessary.These alternatives have less of a physics data base than the tokamakand conventional inertial targets.  Thus,the possibility of successis less certain and the best approach not so clear.  \nIn magnetic confinement,three of the most promising high betaapproaches with a reasonable experimental data base are the FieldReversed Configuration(FRC),the high field tokamak,and the dense Z-pinch.  The best experimental data from an FRC is roughly an order ofmagnitude lower in temperature and 2 orders of magnitude less inLawson nTE than the best tokamak results.(B)  However,these resultswere achieved with a much smaller,less costly experimental device.Also a number of key issues such as control of certain instabilitiesand the establishment of methods for adiabatic compression andtranslation have been resolved.(7)  A high-field tokamak has justbecome operational in the USSR while the Ignitor Apparatus is beingdesigned in Italy.  A related device,CIT,is proposed as a \"next-step”ignition experiment in the U.S.  Z-pinch studies in both the U.S.and Europe have made rapid strides with the discovery that arelatively stable pinch can be formed by passing a high current  \ndischarge through a thin deuterium fiber.  Consequently,there appearsto be a solid physics data base to build on in these areas if adevelopment plan to burn D-3He is desired.  \nThe situation is less clear in inertial confinement where thefirst step requires an experimental demonstration of D~T sparkignition.  It appears that this must wait for the next generation ofhigh-powered laser drivers combined with advanced target designs.  \nIn conclusion,it appears that fusion research has reached apoint in time where an R&D plan to develop a D-3He fusion reactor canbe laid out with some confidence of success.
