Why Titanium

Like aluminum (featured in last newsletter), titanium offers advantages that Atlas utilizes to manufacture the most effective solutions possible for your application: • Once activated, behaves as a getter to absorb hydrogen • Low thermal conductivity • No hydrogen for ultra pure vacuum • No carbon for greatly reduced contamination • Low thermal expansion • … Continued

Loadlock Chamber for Efficiency Upgrade

Denton Vacuum, a leading supplier of production scale thin film technology systems, has added a new Atlas manufactured Loadlock chamber to the Explorer Deposition System in its Customer Application Center (CADC). The loadlock chamber enables the loading and unloading of wafers in a much more efficient way: the semi-automatic feeding also allows the main processing … Continued

Solution at Beneq: Water-Cooled Chamber

Atlas customer, Beneq, a leading supplier of production and research equipment for thin film atomic layer deposition and aerosol coatings, as well as the world’s premier manufacturer of thin film electroluminescent (TFEL) displays, has brought many interesting projects to our design tables and manufacturing facility. Late last year, Beneq brought us a design challenge for … Continued

Solution: Foil Window Flange

Our customers at a large Midwestern research university needed a very thin titanium window for an electron optics application. The idea that they brought to us included a permanently brazed approach that was, unfortunately, thick and expensive to replace if the window failed. The customer wanted it thinner but found the risk of the part … Continued

Atlas Surface Passivation Process

Atlas has overcome the three major obstacles that have inhibited the use of aluminum in extreme vacuum applications… vacuum sealing, vacuum welding and vacuum surface passivation. 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

Studies at NOMAD beamline

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

Emissivac Polished Surface

Atlas has recently developed processes to produce highly polished aluminum surfaces that are UHV and extreme high vacuum (XHV) compatible. Our highly polished aluminum Grade 3 finishes have an RMS level

Titanium: a superior material for XHV

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 Water Traps

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

Aluminum Welding

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

Aluminum Optics Chambers with Breadboard for Max Born

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

Why Aluminum?

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

Aluminum’s Extreme Vacuum Performance

Aluminum’s Extreme Vacuum Performance Any single physical or chemical property of aluminum may be enough reason to select aluminum as a vacuum chamber choice over stainless steel. But when looked at in summary, aluminum overwhelmingly surpasses stainless steel as providing the lowest cost of ownership. Aluminum has seven orders of magnitude less hydrogen than stainless … Continued

Problem – Solution at Fermilab

Our customers at Fermilab needed a series of vacuum chambers that would enable the introduction of electrons to the antiproton beam and the extraction of the electrons from the beam after cooling. In electron cooling, beams of electrons and antiprotons circulate together at the same speed. The “colder” electrons interact with the “hotter” antiprotons and … Continued

John Skaritka Likes Atlas

“Atlas Technologies is one little diamond in a vast wasteland of good intentions,. Their bimetal and aluminum products and problems solving is a very unique skill set that is so valuable. Atlas Technologies is the only company in the country, and possibly the world, that really knows aluminum and they have the ability within bimetal … Continued
