The Neutron Sciences Directorate (NScD) at Oak Ridge National Laboratory (ORNL) operates the High Flux Isotope Reactor
(HFIR), the United States' highest flux reactor based neutron source, and the Spallation Neutron Source (SNS), the world's
most intense pulsed accelerator based neutron source. Together these facilities operate 30 instruments for neutron scattering
research, each year carrying out in excess of 1,000 experiments in the physical, chemical, materials, biological and medical
sciences for more than 3,000 visiting scientists. HFIR also provides unique facilities for isotope production and neutron
irradiation. To learn more about Neutron Sciences at ORNL go to: http://neutrons.ornl.gov.

The Research Accelerator Division (RAD) within NScD invites applications for a post-doctoral research associate position in
its Superconducting Linac (SCL) Systems Group. The SNS SCL is the first accelerator that uses superconducting
radio-frequency (SRF) technology for a pulsed proton machine and is now considered to be the world's leading high-power
SCL proton accelerator facility. The superconducting linac includes various sub-systems such as high-power RF system,
LLRF control system, cryogenic system, and dedicated diagnostic system.
In order to ensure on-going success in the operation, maintenance, and improvement of the SCL, the SNS has been
developing an R&D program in SRF and SCL science and technology. This R&D program aims at better understanding of
and improving SRF cavity surface preparation and performance. Research emphasis will be on developing innovative
techniques to characterize SRF cavity surfaces particularly using non-contact techniques such as laser pump/probe
techniques. The successful candidate should have a strong interest in SRF and SCL systems, and be capable of innovative
and independent research. Mentoring of students is highly encouraged and will be supported.

Major Duties/Responsibilities
- Participate in the design and implementation of new surface characterization techniques for SRF science and technology
under guidance of the SCL Systems Group Physicist.
- Synergize the new surface characterization techniques with surface processing techniques such as plasma processing
- Use and help maintaining instruments related to SRF research (laser, miniSIMS, scanning kelvin probe, FTIR etc.).
- Participates in scientific conferences, workshops, meetings and publishes results in the form of SNS technical notes and
memos, workshop and conference proceedings, and scientific journals.
- Ensures compliance with ESH and quality procedures and programs. May participate in the development and
communication of safety and quality procedures.
- Maintains a strong commitment to the implementation and perpetuation of laboratory values and ethics.

Qualifications Required:
Successful candidates with a recent Ph.D degree in physics, engineering physics, related technical fields, or an equivalent
combination of education and experience will be considered. Experience with experimental equipment such as lasers, mass
spectrometers or surface analysis instruments is required, and familiarity with accelerator systems is also required.
Excellent written and oral communications skills are required along with the desire to work in a team environment on
scientifically challenging problems. Acquiring knowledge of related safety issues, regulations, and safe practices will be
required. Applicants cannot have received the most recent degree more than five years prior to the date of application and
must complete all degree requirements before starting their appointment.

Qualifications Desired:
Ability to work independently, as well as with a team of scientists, engineers, technicians and trades/crafts are desired.
Combination of skills in experimental, theoretical and computing physics is desired.

Work Directions and Interfaces
- Reports to the SCL Systems Group Physicist.
- Keeps strong commitment to team environment dynamics.
Measures of Effectiveness
-Success in the fulfillment of all major duties and responsibility.
-Success as measured by the ORNL Employee Performance Management process.
-Safe execution of all responsibilities in accordance with ORNL ES&H requirements.

This position will remain open for a minimum of 5 days after which it will close when a qualified candidate is identified and/or

We accept Word(.doc, .docx), Excel(.xls, .xlsx), PowerPoint(.ppt, .pptx), Adobe(.pdf), Rich Text Format(.rtf), HTML(.htm,
