10、rticipants reported that some collaboration had begun but felt that more could be accomplished. Discussions between participants at the meeting started to lay the groundwork for new or enhanced collaborations. The responsibility for follow-up on these ideas was left to the individuals involved and w
11、as not documented at the meeting. The group agreed to think about and propose ideas for the next phase of the CRP, as this one will end in 2004. It was suggested that participants circulate ideas for follow-on by mid-2004 so that discussions could occur before the next RCM, which is scheduled for 14
12、-15 October 2004 in Daejon, Republic of Korea. This RCM will be held in conjunction with the Third Technical Meeting on the Physics and Technology of Inertial Fusion Energy Targets and Chambers (11-13 October).2.

Box 808, Livermore, CA 94551 USASynopsisLawrence Livermore National Laboratory (LLNL) is engaged in a broad range of activities that support the development of Inertial Fusion Energy (IFE). The National Ignition Facility (NIF) is being constructed at LLNL, and experiments are alr
22、eady being conducting with the first group of beamlines. The demonstration of ignition on NIF will be an important milestone for IFE. The current schedule calls for completion of all 192 beams by 2009. The ignition campaign will take several years with ignition planned for 2011 or 2012. Our target d
23、esign work includes target concept development and detailed computer simulations to determine the performance of various types of targets (heavy-ion, laser, fast-ignition). In the past year, work on heavy ion targets has shifted from the distributed radiator design to the hybrid target that will acc
24、ommodate large beam spot sizes. For direct-drive laser targets, LLNL has completed implosion calculations using a picket-spike pulse shape, which improves stability of high gain targets. LLNL is conducting experimental and theoretical work on fast ignition and is exploring the possibility of adding
25、PW capability to NIF. LLNL scientists are working with others around the world to understand the physics of the generation and propagation of electrons and ions produced by PW lasers for fast ignition. LLNL has significant activities in both heavy-ion and laser driver development. LLNL is a key memb
26、er of the Heavy Ion Fusion (HIF) Virtual National Laboratory (VNL) that is responsible for developing the science and technology base for using a heavy ion accelerator as a driver for IFE. Several small-scale experiments are being conducted as part of this collaboration including the source/injector
27、 test stand (STS), high current experiment (HCX), and neutralized transport experiment (NTX). The next major facility proposed is the Integrated Beam Experiment (IBX). Our Diode Pumped Solid State Laser (DPSSL) program is developing an efficient, high-repetition-rate laser as a candidate driver. The
28、 Mercury laser has already operated with one amplified head and generated 34 J in single shot and 114 W in average power 5 Hz operations. When the second amplifier head is installed, Mercury is expected to reach its goals of 100 J and 10 Hz at 10% efficiency. Work also continues on chamber and power
29、 plant design studies for both heavy-ion and laser-driven IFE. For the heavy ion driver, the focus continues to be on the thick liquid wall chamber using molten salt. An updated heavy ion fusion power plant design, referred to as the Robust Point Design was completed last year. For laser IFE, the XA
30、PPER pulse x-ray exposure experiment is being used to study damage to candidate materials for first walls and final optics. Currently we have national and international collaborations in all of theses areas. This talk gives an update on progress since the last Research Coordination meeting. *Work pe

32、er Golubev, Alexander Fertman, Sergei KondrashevInstitute for Theoretical and Experimental Physics (ITEP-Moscow) is engaged in a broad range of Heavy Ion Inertial Fusion Energy (IFE) activities supported by Minatom of the Russian Federation. The heavy ion terawatt accumulator facility (ITEP-TWAC) is
33、 being constructed at ITEP, and the non-Liouvillian scenario of the beam accumulation-acceleration has been proven and commissioned. Experiments are already being conducted with the first beams of carbon ions. The current schedule calls for completion of the intensity upgrade in year the 2006 aiming
34、 at 1 TW power of a Cu 27+ ion beam concentrated on a 1 mm spot diameter. Our target design work includes target concept development and detailed computer simulations to determine the performance of various types of heavy-ion targets with fast-ignition. In the past years, work on heavy ion targets h

ITEP is conducting theoretical and experimental work aimed at fast ignition by heavy ion beams and is explor
36、ing the possibility of adding a 300 MHz RF beam wobbling system to the experimental beamline of the TWAC facility.ITEP is a key member of the Research Council of Russian Academy of Science (RAS) that is responsible for analysis and development of the science and technology base for IFE. This Council
37、 brings together the groups from numerous institutes of Minatom RF and RAS pursuing the development of the Heavy Ion IFE power plant concept. The considerations of heavy ion fusion power plant concept based on the fast ignition principle for fusion targets are under development. The cylindrical targ
38、et is irradiated subsequently by a hollow beam in compression phase and by an ignition beam at the burning phase. The ignition is provided by the high energy 100 GeV Pt ions of different masses accelerated in RF-linac. The efficiency of the driver is taken 25%. The main beam delivers 5 MJ energy and
39、 the ignition beam 0.4 MJ to the target. Cylindrical DT filled target provides 600 MJ fusion yield, of which 180 MJ appears in X-rays and ionized debris and 420 MJ in neutrons. The repetition rate is taken as 2 Hz per reactor chamber.The first wall of the blanket employs “liquid wall” approach, part
40、icularly the wetted porous design. The lithium-lead eutectic is used as a coolant, with initial surface temperature of 550C. Computation of neutronics results in blanket energy deposition with maximum density of the order of 108J/m3. The heat conversion system consisting of three coolant loops provi
41、des the net efficiency of the power plant of 35%.Substantial contributions to the field have been achieved recently in numerous national and international collaborations. In this phase, the progressing activities are oriented towards theoretical and experimental investigations of the state of matter
42、 under extreme conditions, experimental and theoretical study on heavy ion beam-plasma interaction, powerful driver issues and to development of computer codes for comprehensive numerical simulations of heavy ion driven IFE in source-to-target scenario. International collaboration plays significant
43、role in ITEP activities. ITEP scientists are working with other laboratories around the world to explore the physics of beam-plasma interaction and High Energy Density physics. The experiments are conducted by joint groups at GSI-Darmstadt, Orsay (France) and in RIKEN (Tokyo). As soon as the beam in
44、tensity of the ITEP-TWAC facility provides specific energy deposition level above 1 kJ/g, the joint international experiments will start.This talk gives an update on the progress in ITEP experimental and theoretical activities since the last Research Coordination meeting. *Work performed under the a
