Position Description:    

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 It is possible in some cases that an offer of employment may be withdrawn.

Postdoctoral Associate (Center for Bright Beams)

Cornell University 

The Cornell Laboratory for Accelerator-based Sciences and Education (CLASSE) has an opening for a postdoctoral research associate within the Center for Bright Beams to work on cutting-edge superconducting materials research. A Ph.D. or an equivalent in physics, material science, electrical engineering, chemical engineering, or chemistry is required. 

Located on campus of a premier Ivy League Research University, CLASSE has a long history of excellence in various aspects of accelerator-related sciences and technology. The Center for Bright Beams (CBB; is an NSF Science and Technology Center, which represents a multi-institutional effort to dramatically improve the quality of accelerator beams. With a multidisciplinary approach, the superconducting materials theme within the Center for Bright Beams offers unique research and career opportunities, and aims at developing methods and materials for next-generation superconducting radio-frequency (SRF) cavities with significantly higher performance levels than the current state-of-the-art ( 

The successful candidate will make core contributions to the SRF activities of CBB, which currently focus on advancing the growth of homogeneous and inhomogeneous thin-film superconductors, on improving the fundamental understanding of related complex material systems, and on advancing the understanding of superconducting response to strong RF fields. The successful candidate will foster collaborations among groups and help define future research directions. The research will be conducted using cutting-edge superconducting RF growth and test infrastructure available at CLASSE, with access to state-of-the-art surface analysis facilities at Cornell Center for Materials Research (CCMR).

Applicants should have experience in at least one of the following areas (multiple areas will be considered definite assets): surface characterization techniques; thin-film superconductors and superconducting materials growth; electrochemistry; superconductor properties characterization; SRF cavity preparation, testing, and data analysis; fundamental RF superconductivity; general superconducting devices.

The initial Postdoctoral Associate appointment will be for one year, with the expectation for renewal for an additional two years. 

Applications should be submitted at ;and should include a cover letter, a CV, 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.
