This is a list of area codes in the U.S. state of Texas. The date of establishment of each area code is indicated in parentheses: [1] 210: San Antonio area; overlays with 726 (November 1, 1992) 214: Dallas area, overlays with 469, 972, and 945 (October 1947) 254: Waco, Killeen, Temple, Belton, Stephenville and North Texas (May 25, 1997) 281 ...
They can be used for solar cells characterisation in a light-beam-induced current (LBIC) experiment, from which the external quantum efficiency (EQE) of a device can be mapped. [15] They can also be used for the characterisation of gold nanoparticles [ 16 ] and single-walled carbon nanotube thermopiles , [ 17 ] where a wide tunable range from ...
The Lunar Sample Laboratory Facility (LSLF) is a repository and laboratory facility at NASA's Lyndon B. Johnson Space Center in Houston, Texas, opened in 1979 to house geologic samples returned from the Moon by the Apollo program missions to the lunar surface between 1969 and 1972. The facility preserves most of the 382 kilograms (842 lb) of ...
When the laser strikes an area containing a short circuit, localized heating occurs. This heating changes the resistance of the short, resulting in a change in power consumption of the device. These changes in power consumption are plotted onto an image of the device in locations corresponding to the position of the laser at the time that the ...
The first large-scale experiments were performed in June 2009 [7] and the first "integrated ignition experiments" (which tested the laser's power) were declared completed in October 2010. [ 8 ] From 2009 to 2012 experiments were conducted under the National Ignition Campaign, with the goal of reaching ignition just after the laser reached full ...
The Trident Laser has been decommissioned, with final experiments in 2017, and is now in storage at the University of Texas at Austin. The Trident Laser consisted of three main laser chains (A,B, and C) of neodymium glass amplifiers (or Nd:glass), two identical longpulse beams lines, A&B, and a third beamline, C, that could be operated either ...
The first working model of the laser was created at Hughes Research Laboratories in 1960 by Theodore Maiman (1927–2007). HRL began research on atomic clocks in 1959. In the late 1970s they produced experimental maser oscillators for NRL, which eventually led to space-based GPS atomic clocks. HRL began research on ion propulsion in 1960. [4]
Laser-induced breakdown spectroscopy (LIBS) is a type of atomic emission spectroscopy which uses a highly energetic laser pulse as the excitation source. [1] [2] The laser is focused to form a plasma, which atomizes and excites samples. The formation of the plasma only begins when the focused laser achieves a certain threshold for optical ...
