ANL APS, APS-U, and Televac®
Televac® partnered with Argonne National Laboratory (ANL)with their Advanced Photon Source (APS). At APS there is asynchrotron where electrons are accelerated to near the speedof light for experimentation. The synchrotron facility includes alinear accelerator, booster synchrotron, and storage ring. In thelinear accelerator there’s a hot cathode which produces electrons,and using the different accelerators (linear and synchrotron), theelectrons are accelerated to 99.999+% the speed of light. In thelinear accelerator the electrons reach an energy of around 450 MeVprior to being injected into the booster synchrotron where theyreach 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, andsignificant technological advancements have taken place since theoriginal installation. In 2020, APS launched a project called the APS-U(Advanced Photon Source - Upgrade) to upgrade the acceleratorsand 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 astorage ring circumference of around 1.1 km or 3,600 feet.

The Challenge and The Solution
APS-U had stringent vacuum measurement requirements for theupgrade with a tight schedule, and that’s where Televac® came in.

Televac-ANL-Case-Study rev -vacuum controller was selected along with our industryleading convection vacuum gauge (the Televac® 4A) anddouble-inverted magnetron cold cathode vacuum gauge(the Televac® 7FCS). This vacuum gauging configuration
allowed for wide range, high accuracy vacuum
measurement from above atmosphere (1000 Torr) down
to UHV or 1*10-11 Torr.
The unique design of the Televac® 7FCS cold cathode waswell-suited for the APS-U requirements for three reasons;
it includes a thermionic emitter, it has a double-inverted
magnetron design, and it’s cleanable. The thermionic
emitter, or starter filament, allows the cold cathodeto start quickly in UHV, solving challenges related theAPS-U requirement for starting cold cathodes in UHV.
The double-inverted magnetron design reduces straymagnetic fields and provides a wider measurement range

than typical cold cathodes (down to 1*10-11 Torr), allowing
accurate UHV measurement critical to APS-U. The easycleanability means that the gauge will last indefinitely inan application like that of APS-U, where equipment mustremain in operation for decades at a time with little or nointervention from operators.
Other unique design features of the vacuum measurement
system offered by Televac® included radiation resistanceof the gauges and cables, EPICS/synApps compatibility

via RS-232 communications, ultra-fast sampling andresponse times of the vacuum gauges down to ≤10 ms, up
to 8 process control relay set points that can be assigned
to any of the connected vacuum gauges, and up to 8vacuum gauges simultaneously controlled and displayed
by a single MX200 vacuum controller. The flexibility andfast lead times of Televac® also allowed us to meet alldelivery requirements for APS-U. To read more about ourvacuum gauging solutions for particle accelerators andsynchrotrons, visit our dedicated page for this market andapplication.
