This position is located in Livingston, LA.

Life at LIGO Livingston as a Caltech Employee
LIGO’s observatory in rural Livingston Parish, Louisiana, is an approximately 35-minute commute from Baton Rouge, LA., and is about 1 hour 20 minutes from New Orleans. Caltech employs a staff of 42 at the Livingston observatory. Caltech has an extraordinary science impact across many fields. Its small size creates a community where innovation and collaboration are the norm. Caltech manages the Jet Propulsion Laboratory (JPL) for NASA, the leading US center for the robotic exploration of the Solar System. Caltech also operates large-scale research facilities such as the Palomar and Keck Observatories.

South Louisiana enjoys a friendly and unique blend of cultures, food, art, music and festivals—including Mardi Gras each spring. Baton Rouge, the State capital, hosts Louisiana State University. New Orleans, founded in 1718, is one of the most distinctive and well-known cities in the Americas, and is considered the birthplace of jazz. The region along the Mississippi River, which flows through both cities, includes a significant petrochemical industry base and several high-volume shipping ports. Area rivers, lakes and the Gulf of Mexico provide opportunities for recreation and fishing.

People choose to work at LIGO for many reasons, often with fulfilling, long-term careers. LIGO is a family-friendly laboratory and strives to ensure everyone is able to achieve the work-life balance they desire. Employees have access to a wide range of benefits including a child-care assistance program. Caltech’s benefits program offers a quality, competitive benefits package that is affordable for you and the Institute.

Job Duties

The LIGO observatories each operate a 10 million liter ultra-high-vacuum (UHV) system that consists of 8 km of meter-wide vacuum pipe and numerous interconnected chambers, among the largest such systems in the World. They each include 8 km of 1.2m-diameter beam tube, interconnecting approximately ten 3m-diameter vessels that house the detector apparatus. LIGO detectors operate in the 10 -9 Torr pressure range, relying on a combination of cryogenic, turbomolecular, ion and getter pump technologies, combined with stringent material and operating protocols. Its technologies include cryogenic, turbo-molecular, and ion pumps, and residual gas analyzers.
