Image: NIF output over 11 years without legend

Description: Target gain factor plotted versus experiment number for inertial fusion experiments at the National Ignition Facility. The gain factors are shown on a logarithmic scale. The horizontal labels mark the beginning of each year. The dashed horizontal line represents a target gain factor of 1, also known as scientific breakeven, the National Academy of Sciences definition of ignition. The color of the narrow bars represents different implosion designs, and the color of the background stripes represents broad trends in implosion design in any given year:   Plastic ablator   Mitigation of high-Z mix   Diamond ablators, increased efficiency via reduced LPI   Increased coupling with larger capsules, symmetry controlled via cross-beam energy transfer & hohlraum geometry     Improved implosion design and increased laser energy
