Scope Of Work

Televac® partnered with Argonne National Laboratory (ANL) with their Advanced Photon Source (APS). At APS there is a synchrotron where electrons are accelerated to near the speed of light for experimentation. The synchrotron facility includes a linear accelerator, booster synchrotron, and storage ring. In the linear accelerator there’s a hot cathode which produces electrons, and using the different accelerators (linear and synchrotron), the electrons are accelerated to 99.999+% the speed of light. In the linear accelerator the electrons reach an energy of around 450 MeV prior to being injected into the booster synchrotron where they reach an energy of around 7 GeV. The linear accelerator, booster synchrotron, and storage ring are kept in ultra-high vacuum (UHV) at all times to prevent the accelerated electrons from colliding with other particles as they travel at close to light speed. APS was originally brought online in 1995, and significant technological advancements have taken place since the original installation. In 2020, APS launched a project called the APS-U (Advanced Photon Source - Upgrade) to upgrade the accelerators and storage ring with all new equipment. This included the vacuum gauging, with hundreds of new vacuum controllers and vacuum gauges needed to measure across the massive facility that has a storage ring circumference of around 1.1 km or 3,600 feet. The Challenge and The Solution APS-U had stringent vacuum measurement requirements for the upgrade with a tight schedule, and that’s where Televac® came in. Working directly with the APS-U team, Televac®’s versatile MX200
