OMEGA EP: High-energy petawatt capability for the OMEGA laser facility
OMEGA EP (Extended Performance) is a petawatt-class
addition to the existing 30-kJ,
60-beam OMEGA Laser Facility at the University of Rochester. When completed,
it will consist of four beamlines, each capable of producing up to 6.5âkJ at
351ânm in a 1 to 10âns pulse. Two of the beamlines will produce up to 2.6âkJ
in a pulse-width range of 1 to 100âps at 1053ânm using chirped-pulse
amplification (CPA). This paper reviews both the OMEGA EP performance
objectives and the enabling technologies required to meet these goals

Progress in direct-drive inertial confinement fusion
Significant progress has been made in direct-drive inertial confinement fusion research at the Laboratory for Laser Energetics since the 2009 IFSA Conference [R.L. McCrory et al., J. Phys.: Conf. Ser. 244, 012004 (2010)]. Areal densities of 300mg/cm2 have been measured in cryogenic target implosions with neutron yields 15% of 1-D predictions. A model of crossed-beam energy transfer has been developed to explain the observed scattered-light spectrum and laserâtarget coupling. Experiments show that its impact can be mitigated by changing the ratio of the laser beam to target diameter. Progress continues in the development of the polar-drive concept that will allow direct-driveâignition experiments to be conducted on the National Ignition Facility using the indirect-drive-beam layout
