Hamamatsu Edges Closer to Compact Laser Fusion Source
HAMAMATSU, Japan, Jan. 13, 2023 — Building on an existing multiyear R&D pursuit to establish technology that produces laser pulses at 250 J with a repetition rate of 10 Hz, Hamamatsu Photonics has developed a laser system that produced pulses with an energy of 100 J at a repetition rate of 10 Hz. The company said that it achieved the result by increasing the cooling capacity for the laser medium of its pulsed laser system, and by optimizing the output of the laser diode (LD) module for pumping. In a report detailing
X-Ray Laser Achieves Its Final, Colder-Than-Space Temperature
MENLO PARK, Calif., May 12, 2022 — The superconducting particle accelerator, an upgrade to the Linac Coherent Light Source (LCLS) x-ray free-electron laser at the U.S. Department of Energy’s SLAC National Accelerator Laboratory, has been cooled to a temperature of −456...
Global Helium Market Swings to Oversupply
HOUSTON, Nov. 8, 2016 — The global market for helium, an inert gas essential for medical resonance imaging (MRI), semiconductors, welding and other manufacturing and industrial uses, is growing at 2 percent per year. That is less than the anticipated production rate since...
Gigaphoton Develops Helium-Free Laser Purge Process
OYAMA, Japan, June 30, 2014 — Gigaphoton recently announced two advancements for lithography lasers: a helium-free purge process and a high-power laser prototype. The helium-free purge process for argon-fluorine (ArF) immersion lasers uses nitrogen, an abundant gas the company...
Colonies on the Moon and the Economy of an Irish Pub
Jan 31, 2012 — Some 20 years ago, in the crowded back room of an Irish pub in Saratoga Springs, N.Y., two or three friends and I came up with a truly inspired plan: We would push a couple of tables together, raise a tiny flag and declare ourselves a sovereign...
Synchrotron x-rays from a tabletop source
LONDON – A tabletop instrument in development may have the potential to produce bright, spatially coherent synchrotron x-rays similar in energy and quality to those generated by some of the largest x-ray facilities in the world. Such x-rays could enable...
New Helium Plant to be Built
LEHIGH VALLEY, Pa., Dec. 1, 2010 — Matheson, a member of the Taiyo Nippon Sanso Corp. (TNSC) group, and Air Products have announced that construction has begun on a jointly owned liquid helium production plant near Big Piney, Wyo. Designed to produce 200 million standard cubic feet...
Nova Explosion Reveals Gamma Rays
WASHINGTON, Aug. 25, 2010 — Using the Large Area Telescope (LAT) onboard NASA's Fermi Gamma-ray Space Telescope satellite, astronomers have detected gamma rays from a nova for the first time, a finding that surprises both observers and theorists. The discovery dispels the...
The Proton Just Got Smaller
VILLIGEN, Switzerland, July 12, 2010 — In a discovery that could poke holes in the theory of quantum electrodynamics (QED), scientists have discovered that the proton, one of the smallest building blocks of all matter, is actually 4 percent smaller than previously thought. Part of the...
Cadillacs, Congress and the Helium Reserve
Mar 2, 2010 — Here’s an interesting bit of trivia: the Cadillac Ranch, the peculiar paean to the open road that lies just west of Amarillo, Tex., was created under the patronage of Stanley Marsh 3, a local, rather eccentric helium tycoon. The National Helium...
LHC: The Beams are Back
GENEVA, Nov. 23, 2009 – Particle beams are once again circulating in the Large Hadron Collider (LHC), 14 months after an electrical failure caused serious damage to the world’s most powerful particle accelerator, which straddles the borders of France and Switzerland and is...
Mid-IR Tunable Lasers Probe Hydrocarbon Molecules
Sep 1, 2009 — Infrared laser spectroscopy is a powerful technique that allows unique identification of chemical species as well as study of their properties. Measuring absorption as a function of wavelength enables chemists to obtain spectra of compounds that are...
CERN Parties Like It’s 2009
GENEVA, Oct. 21, 2008 -- Despite a malfunction that has shuttered the world’s largest particle accelerator until 2009, officials at CERN, the organization hosting the ailing atom smasher, held an inauguration ceremony today. Attending the celebration to inaugurate the...
The Main Extraction: Helium Production in the US
Oct 14, 2008 — Helium, especially highly purified versions, has been increasingly in demand globally for its usefulness in high tech applications. Here is a brief history of helium production in the US.
Helium: Up, Up and Away?
Oct 1, 2008 — Refiners are struggling to keep up with demand, prices have increased dramatically over the past few years, and debate is raging over depleting federal reserves. If you think the subject is oil, think again. Helium, the most important supercoolant...
LHC: No Smashing Until Spring
GENEVA, Sept. 23, 2008 -- Investigation into the cause of a large helium leak at the Large Hadron Collider (LHC) and repairs to the magnets that quenched during the leak mean the atom smasher won’t restart until spring 2009, officials at CERN, the organization hosting...
LHC Repairs to Take Months
GENEVA, Sept. 22, 2008 -- A faulty electrical connection between two magnets was most likely the cause of a magnet quench Friday that resulted in a large helium leak at the Large Hadron Collider (LHC), the world’s largest particle accelerator, and will mean the...
Quench Latest LHC Setback
GENEVA, Sept. 19, 2008 -- A magnet quench Friday that resulted in a large helium leak is the latest setback for the Large Hadron Collider (LHC), the world's largest particle accelerator, which was launched with great fanfare last week. The LHC contains hundreds of...
Helium Demand Ballooning
AMARILLO, Texas, Oct. 19, 2007 -- The worldwide shortage of helium is resulting in rising prices and tight supplies for party supply stores, but it won't deflate Macy's annual tradition of floating gigantic characters down Broadway in New York City this Thanksgiving. An...
Alis Acquired by Carl Zeiss SMT
OBERKOCHEN, Germany, Sept. 14, 2006 -- Carl Zeiss SMT AG this week closed its acquisition of Peabody, Mass.-based Alis Corp., a nanotechnology startup developing scanning ion microscopes and imaging systems. Specific terms of the deal were not disclosed. Carl Zeiss SMT, a provider of...
New Imaging Method Uses Helium Atoms
EUGENE, Ore., Aug. 1, 2006 -- A newly devised nozzle fitted with a pinhole-sized capillary has allowed researchers to distribute helium atoms with x-ray-like waves on randomly shaped surfaces. The technique could power the development of a new microscope for nanotechnology,...
