Job Summary
Caltech’s Laser Interferometer Gravitational-wave Observatory (LIGO) seeks a highly motivated and skilled Senior Vacuum Engineer to join its Cosmic Explorer Beamtube Experiment (CEBEX) team at the Richland, Washington observatory site.
LIGO Laboratory is a major National Science Foundation facility dedicated to observing the newly discovered gravitational-wave universe. Jointly operated by the California Institute of Technology and the Massachusetts Institute of Technology, LIGO operates the world’s leading gravitational observatories near Richland, WA and Baton Rouge, LA, as well as campus R&D centers in Pasadena, CA and Cambridge, MA.
This position is a fulltime in-person role located at LIGO Hanford in Richland, WA.
To learn more about LIGO Laboratory, please visit LIGO.caltech.edu. The Laboratory’s mission supports the young science of gravitational-wave physics and astronomy and includes observatory operations, analysis and dissemination of astrophysical observations, detector science and technology R&D, gravitational-wave astrophysics, and education and public outreach.
LIGO now also leads the effort to expand humanity’s gravitational wave horizon with a next-generation observatory, Cosmic Explorer (CE). Slated for construction in the 2030’s, CE will be ten times the size and reach of LIGO, able to gather signals from the edge of the observable universe.
The selected applicant will join an elite team charged with conceiving, designing, building, and testing advanced technology for the CE vacuum systems, destined to be the largest ultrahigh vacuum systems ever built. We will exercise and develop this technology in a new, purpose-built UHV research facility, the Cosmic Explorer Beamtube Experiment (CEBEX) Laboratory, located at LIGO Hanford.
Current Washington and Louisiana LIGO installations occupy 4 km scale, 10 million-liter UHV systems operating at one trillionth of atmospheric pressure (10-9 millibar), making them the two largest contiguous UHV volumes ever constructed. To further expand sensitivity, a new observatory will be constructed: Cosmic Explorer (CE). This observatory will require beamtubes 10x longer, up to 40 km in length. This will multiply CE’s detectable source range by ten, increasing the accessible volume of space thousandfold. However, UHV structures of this size and volume have never been attempted.
As a key member of the Cosmic Explorer Beamtube Experiment (CEBEX) team, the selectee will contribute to the modeling, trade study, design, fabrication, installation, bakeout and characterization of engineering prototypes and technology demonstrators for CE beamtubes up to 40 km in length. Tests will include industrial fabrication and qualification of a planned 1.2-meter diameter, 120-meter-long demonstration tube, to be erected in the new purpose-built CEBEX laboratory at the LIGO Hanford Observatory (LHO). In parallel, the chosen candidate will take a lead role in forging results of these investigations into a conceptual reference design, construction plan, and parametric cost estimate for CE. These will form the core of our future CE Observatory construction proposal.
This is a Campus Critical position. An employee designated as campus critical is expected to be aware of the campus emergency management plan and to report to Campus as soon as possible in the event of an emergency to assist in campus wide response and recovery efforts.
