Lawrence Livermore National Laboratory

Naval Air Station Livermore was a United States Navy military facility located in Livermore, California.

The National Ignition Facility (NIF) is a laser-based inertial confinement fusion (ICF) research device, located at Lawrence Livermore National Laboratory in Livermore, California, United States. NIF's mission is to achieve fusion ignition with high energy gain. It achieved the first instance of scientific breakeven controlled fusion in an experiment on December 5, 2022, with an energy gain factor of 1.5. It supports nuclear weapon maintenance and design by studying the behavior of matter under the conditions found within nuclear explosions.NIF is the largest and most powerful ICF device built to date. The basic ICF concept is to squeeze a small amount of fuel to reach pressure and temperature necessary for fusion. NIF hosts the world's most energetic laser. The laser heats the outer layer of a small sphere. The energy is so intense that it causes the sphere to implode, squeezing the fuel inside. The implosion reaches a peak speed of 350 km/s (0.35 mm/ns), raising the fuel density from about that of water to about 100 times that of lead. The delivery of energy and the adiabatic process during implosion raises the temperature of the fuel to hundreds of millions of degrees. At these temperatures, fusion processes occur in the tiny interval before the fuel explodes outward. Construction on the NIF began in 1997. NIF was completed five years behind schedule and cost almost four times its original budget. Construction was certified complete on March 31, 2009, by the U.S. Department of Energy. The first large-scale experiments were performed in June 2009 and the first "integrated ignition experiments" (which tested the laser's power) were declared completed in October 2010.From 2009 to 2012 experiments were conducted under the National Ignition Campaign, with the goal of reaching ignition just after the laser reached full power, some time in the second half of 2012. The campaign officially ended in September 2012, at about 1⁄10 the conditions needed for ignition. Thereafter NIF has been used primarily for materials science and weapons research. In 2021, after improvements in fuel target design, NIF produced 70% of the energy of the laser, beating the record set in 1997 by the JET reactor at 67% and achieving a burning plasma. On December 5, 2022, after further technical improvements, NIF reached "ignition", or scientific breakeven, for the first time, achieving a 154% energy yield.

Vasco Road station (signed as Vasco) is an ACE station on Vasco Road in eastern Livermore, California. The station mainly serves the workers of Lawrence Livermore National Laboratory, Sandia National Laboratory and the surrounding industrial and office parks in eastern Livermore in addition to commuters from Livermore headed to job centers in the Silicon Valley to the southwest. BART approved an alignment for its Livermore extension to run along Interstate 580 then tunnel underneath Isabel Avenue to the Livermore ACE station and then continue along the right-of-way to Vasco Road to serve as its final terminal. However, in July 2011, the Livermore City Council reversed its position in response to a petition requesting that the alignment stay within or nearby the Interstate 580 right-of-way, and now favors stations be built at the Interstate 580 interchanges with Isabel Avenue and Greenville Road. The BART extension was later replaced with the Valley Link proposal, again along the I-580 alignment.

Ulmar (formerly, Ulmar Siding) is a former unincorporated community now annexed to Livermore in Alameda County, California. It lies at an elevation of 551 feet (168 m). This former siding has median estimated value of $777,110 and expected growth rate of 2.40% for 2017-2022 according to that survey.

The Livermore Valley, historically known as the Valle de San José (Valley of San José), is a valley in Alameda County, California, located in the East Bay region. The city of Livermore is located in the valley.

Southfront Road is a planned railway station in Livermore, California. It is a stop on the planned Valley Link system. Rush hour short turn Valley Link trains would operate from here to Dublin/Pleasanton. Service is expected to start as early as 2028.

The Centennial Light is the world's longest-lasting light bulb, burning since 1901, and almost never turned off. It is located at 4550 East Avenue, Livermore, California, and maintained by the Livermore-Pleasanton Fire Department. Due to its longevity, the bulb has been noted by The Guinness Book of World Records, Ripley's Believe It or Not!, and General Electric.

Trevarno, California is a section of Livermore, Alameda County, California, built by a Cornish company, based at Trevarno, near Helston, manufacturing safety fuses. It is between First Street and the railroad and lies at an elevation of 535 feet (163 m). Trevarno is Cornish and means "farm/settlement of Varno." For more information, see Cornish surnames. Officials of Coast Manufacturing and Supply Company in Livermore named the area after George Bickford's home in Cornwall. The company made safety fuses invented by William Bickford, George's father.

Concannon Vineyard is the second-largest winery in the Livermore Valley of California, producing around 30,000 cases annually. It is well known for its Petite Sirah and Concannon was the first winery to bottle this grape as a varietal wine in 1961. Prior to 1961, the petite sirah grape was produced worldwide as a blend wine. It also produces several other varieties of wine, including Chardonnay and Cabernet Sauvingnon. Concannon is owned by The Wine Group.

The Clayton-Marsh Creek-Greenville Fault is a fault located in the eastern San Francisco Bay Area of California, in Alameda County and Contra Costa County. It is part of the somewhat parallel system of faults that are secondary to the San Andreas Fault.

Livermore Sanitarium was a private sanitarium and psychiatric hospital, located in Livermore, California, in operation from 1894 until 1965. The facility specialized the treatment and research of alcoholism and mental disorders. During this time period the Livermore Valley was considered an ideal climate for optimizing one's health.

Arroyo Seco is an 11.7-mile-long (18.8 km) watercourse in Alameda County, California, that traverses through the city of Livermore, emptying into Arroyo Las Positas. Arroyo Seco means "dry stream" in Spanish. Arroyo Seco lies above the Arroyo Seco watershed, which includes the eastern part of the city of Livermore and also the Sandia National Laboratory. The Mocho Subbasin is the largest of the subbasins in the Livermore Valley watershed. This subbasin is bounded to the west by the Livermore Fault Zone and to the east by the Tesla Fault. Some groundwater flow occurs across these fault boundaries, but flows are discontinuous below a depth of 50 feet (15 m) across the Tesla Fault and south of the Arroyo Mocho channel across the Livermore Fault. A number of threatened and endangered species reside in this watershed.
