As part of the university's comprehensive vaccination program, all Cornell employees are required to have and provide proof of an FDA-or WHO-authorized or approved COVID-19 vaccine and booster or have obtained a university-approved disability/medical or religious exemption, regardless of their role and work location.

New hires are required to provide documentation showing full vaccination status (that is, completion of two shots of the Moderna or Pfizer vaccine or one shot of the Janssen/Johnson & Johnson) before their first day of work. If a new hire's vaccination is not complete or information is not received by their start date, the first day of work will be delayed. It is possible in some cases that an offer of employment may be withdrawn.

SRF Group Research Associate Cornell University

CLASSE (Cornell Laboratory for Accelerator-based Sciences and Education) has an opening for a Research Associate position in the SRF (Superconducting Radio Frequency) Group. This position requires a doctoral degree in physics or applied physics, with experience in SRF operation and research.

Cornell’s SRF Group conducts a wide variety of fundamental SRF science and technology R&D activities, and currently supports two SRF driven accelerators at CLASSE: the Cornell Electron Storage Ring CESR, and CBETA, a novel Energy-Recovery-Linac test accelerator.

The successful candidate’s focus will be on (1) the development, commissioning, operation, and optimization of RF and SRF accelerator systems for CESR, with ample opportunities for cutting-edge research and career development, and (2) on conducting and leading fundamental SRF research activities, including the development of stand-alone compact SRF modules based on next-generation Nb3Sn SRF cavities.

This is an initial 3-year appointment with expectation for renewal, subject to mutual satisfaction and availability of funds. Applicants should have demonstrated experience in at least one of the following areas (multiple areas will be considered definite assets): SRF cavity fabrication, preparation, cryogenic testing, and data analysis; SRF technology design, fabrication, commissioning, and operation; RF simulations and measurements; RF technology, LLRF and microphonics control for SRF accelerators. Strong written and verbal communication skills as well as the ability to work independently and in a diverse team are expected.

Located on the campus of a premier Ivy League Research University, CLASSE has a long history of excellence in various aspects of accelerator-related sciences and technology. Cornell provides an intellectually stimulating research environment with opportunities to work with undergraduate and graduate students on collaborative research. Cornell’s SRF group has strong worldwide collaborations with laboratories and industrial partners, and the successful candidate is expected to further foster these.

Applications should be submitted at and should include a cover letter, a CV, a list of publications, and a detailed summary of research experience and interests. Applicants must arrange to have at least three letters of recommendation uploaded, as per instructions on the academicjobsonline website. For information about the position, contact Dr. Matthias Liepe at
