60 Years of DESY: From Hamburg Particle Accelerator to Global Research Center

For the past 60 years, fundamental research has been carried out at the Deutsches Elektronen-Synchrotron (DESY) in Hamburg-Bahrenfeld. In those 60 years, DESY has become a world leader in accelerator technology, structure research, particle physics and astroparticle physics. DESY has developed pioneering technologies, which have been used by scientists from...

The Pocket-Sized Particle Accelerator

The accelerator-on-a-chip is just a prototype, but its design and fabrication techniques can be scaled up to deliver particle beams accelerated enough to perform cutting-edge experiments that don’t require the power of a massive accelerator. By placing these chips in a series, researchers from SLAC National Laboratory and Stanford University...

QuinStar Completes Contribution to NASA Mission

QuinStar (CSA CSM) has successfully completed a 28-month program with the Jet Propulsion Laboratory that developed flight hardware for the NASA-ISRO (Indian Space Research Organization) Synthetic Aperture Radar (NISAR) mission. QuinStar’s deliverables included Ka-band solid-state power amplifiers—an enabling element of the communication payload for the high speed, space-to-earth datalink.

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

Containing ice accumulation while recovering helium

We are implementing a system to recover helium from our Janis ST-500 continuous flow LHe cryostat. The recovery system uses standard 1/4″ plastic tubing, which we connect directly to the cryostat’s exhaust port. The problem with this setup is that the gas is still quite cold as it leaves the...
