Applying our knowledge and proprietary technology we produce state-of-the-art aluminum vacuum chambers that deliver the revolutionary physical and vacuum properties of aluminum at dramatic cost savings. Atlas Vacuum Surface … Continued
New version Dr. Ken Kelton of Washington University in St. Louis is preparing to make studies of the atomic structures of metallic liquids at the Spallation Neutron Source on the NOMAD (Nanoscale-Ordered Materials Diffractometer) beam line. Part of the NESL (Neutron ElectroStatic Levitation) facility built by Dr. Kelton and his team includes an aluminum Atlas … Continued
Atlas Technologies introduces a process that generates highly polished aluminum surfaces that is UHV and Extreme High Vacuum (XHV) compatible. Emissivac Grade 3 finish holds an RMS level of <8 micro inches and approaches a mirror-like finish on the interior walls of vacuum chambers. On its own, aluminum boasts superior thermal emissivity and outgassing … Continued
Atlas titanium chambers offer extreme vacuum performance with very low hydrogen permeation rates and secondary gasses. Due to the gettering properties of this metal, titanium vacuum chambers are, in many ways, the ultimate vacuum material. For extreme high vacuum, titanium will often be the best choice. But, due to cost of the material and the … Continued
Vergason Technologies, Inc., a leading global innovator in sputtering, thermal evaporation, and cathodic arc thin film coating technologies, is utilizing Atlas manufactured aluminum water traps to improve cycle time, product quality, and overall system efficiency in their Press-Side® Rapid Cycle Metalizers. The water traps help reduce the amount of water vapor that is pumped out … Continued
Exciting news for NSLS-II at BNL and their users! Mr. Dick Hseuh, the Vacuum Group Leader for NSLS ll and responsible party for the design, construction, and overall commissioning of the vacuum systems in the NSLS ll accelerator complex, tells us that they are currently commissioning their Booster with beam and plan to start storage … Continued
Welding Reference Information for Designers and Welders of Aluminum Ultra High Vacuum (UHV) Chambers Aluminum UHV Weld Design Most facilities familiar with Ultra High Vacuum (UHV) have experience welding stainless steel to UHV standards; however, many have not had occasion to weld aluminum to UHV standards. We offer this brief guide for designing and welding … Continued
Several Atlas aluminum vacuum chambers with breadboards installed at Max Born in Berlin are used for the generation and application of ultra short x-ray pulses via a frequency conversion process called high order harmonic generation. The purpose is to record films of atoms and molecules on their natural time scales from the femtosecond (10^-15 seconds) … Continued
The Aluminum Advantage Industry leaders at Atlas allow you to take full advantage of the benefits of aluminum over stainless steel: 10x the thermal conductivity and 21 x the thermal diffusivity for fast, complete bakeouts and unmatched thermal performance 7 orders of magnitude less hydrogen for ultra pure vacuum Less carbon for reduced contamination Outgassing … Continued
Adhering to UHV standards in cryogenic applications with stainless steel is a process with which many manufacturers are familiar. Most, however, aren’t experienced or qualified to apply those same standards to cryogenic applications when it comes to bimetal solutions; most often involving aluminum. Since the closing of Bi-Braze, increasing numbers of customers have looked to … Continued
Our customers at Dynavac are crucial participants in a compelling project for NASA’s Magnetospheric Multiscale Mission at the Goddard Space Center. The Solar Terrestrial Probes mission will fly four identically instrumented satellites to investigate how the sun and Earth’s magnetic fields transfer energy from one to the other. This transfer, called Magnetic Reconnection, affects space … Continued
