A abundância de vestigios de superficie romanos na Madanela justificou uma primeira tentativa de definir o sitio. Os dados continuam parcos apos apenas uma campanha, mas a identificacao de estruturas e materiais assegura um intervalo cronologico credivel. Um dos achados mais interessantes consiste num conjunto monetario de meados do seculo IV.

OMEGA is a 60-terawatt, 60-beam, frequency-tripled Nd:glass laser system designed to perform precision direct-drive inertial-confinement-fusion (ICF) experiments. The upgrade to the system, completed in April 1995, met or surpassed all technical requirements. The acceptance tests demonstrated exceptional performance throughout the system: high driver stability (< 2% variations), precise control of the beam profiles and amplifier gains, 75% frequency-conversion efficiency, beam energy balance less than ...

We report on fusion research at the University of Rochester's Laboratory for Laser Energetics. We describe the configuration of the upgrade to the OMEGA laser system—a 30-kJ, 351-nm, 60-beam, Nd:glass, direct-drive laser-fusion system. The system utilizes rod and disk amplifiers and frequency-tripling to produce intense UV. Target irradiation uniformity is controlled using phase conversion and smoothing by spectral dispersion (SSD). Dual driver lines will feed the propagation of two coaxial beams ...

We carried out a set of experiments on the Omega laser facility at Rochester with Laser MegaJoule like indirect drive irradiation. We studied the irradiation non-uniformity with the foam ball radiography technique and the implosion symmetry with (D 2 + Argon) filed capsules core emission. Cylindrical 'Nova scale 1' thin wall hohlraums were used. Forty of the Omega beams, arranged in three cones on each side of the hohlraum were used to create the x-ray drive. Eight additional beams were used on a Ti ...

Funding for the OMEGA laser Upgrade project has been approved and the design of a 30-kJ, 351-nm, 60-beam laser system has begun. This system will provide a unique capability to validate high-performance, direct-drive laser-fusion targets. We highlight various design features of a system that will attain 1% - 2% irradiation uniformity with versatile pulse shaping, thus providing a wide range of irradiation options for direct-drive experiments. The Nd:glass laser system consists of 60 beamlines using ...

For more than half a century, researchers around the world have been engaged in attempts to achieve fusion ignition as a proof of principle of various fusion concepts. Following the Lawson criterion, an ignited plasma is one where the fusion heating power is high enough to overcome all the physical processes that cool the fusion plasma, creating a positive thermodynamic feedback loop with rapidly increasing temperature. In inertially confined fusion, ignition is a state where the fusion plasma can ...

On December 5, 2022, an indirect drive fusion implosion on the National Ignition Facility (NIF) achieved a target gain G target of 1.5. This is the first laboratory demonstration of exceeding “scientific breakeven” (or G target > 1 ) where 2.05 MJ of 351 nm laser light produced 3.1 MJ of total fusion yield, a result which significantly exceeds the Lawson criterion for fusion ignition as reported in a previous NIF implosion [H. Abu-Shawareb (Indirect Drive ICF Collaboration), ]. This achievement is the culmination ...

The upgrade to the OMEGA laser system, a 30-kJ, 351-nm, 60-beam direct-drive laser-fusion system is reported here. The system configuration is presented along with the status of its construction and the plans for system activation. The system utilizes rod and disk amplifiers and frequency tripling to produce UV pulses which are smoothed using phase conversion and smoothing by spectral dispersion. Dual driver lines will feed the propagation of two co-axial beams, which have different pulse widths ...

Direct-drive laser-fusion ignition experiments rely on detailed understanding and control of irradiation uniformity, the Rayleigh-Taylor instability, and target fabrication. LLE is investigating various theoretical aspects of a direct-drive NIF ignition target based on an 'all-DT' design: a spherical target of approximately 3.5-mm diameter, 1 to 2 micrometers of CH wall thickness, and an approximately 350-micrometers DT-ice layer near the triple point of DT. OMEGA experiments are designed to address ...
