What Your Job Will Be Like:

JLab is seeking an entry level SRF accelerator scientist (Staff Scientist I) to join the electron ion collider (EIC) project. The EIC is a new project under construction in partnership between Jefferson Lab and Brookhaven National Lab. It is a technically challenging machine that will be the flagship for nuclear physics and the only operating collider in the USA for the foreseeable future. Jefferson Lab will have a lead role in developing the new SRF systems for EIC. This position is an opportunity to get in on the ground floor of this exciting development.

Under general direction, the incumbent will perform SRF cavity and system development for the EIC, including RF structure modeling, design, prototyping and testing, higher-order mode (HOM) coupler development, fundamental power coupler (FPC) development, system integration and controls. It is expected that up to 25% of time will be available to participate in broader SRF R&D activities such as material and process
development and testing, CEBAF and other test accelerator operations, basic R&D and participation in other projects.

As an entry level scientist, your role will:

Deliver technical solutions to assigned problems individually or as part of a larger team, including SRF cavity or component design and optimization to achieve specific objectives such as shunt impedance, peak surface fields, HOM damping or multipacting;

Work with a larger team on the RF thermal/mechanical design and optimization, fabrication, processing, treatment, as well as the control and testing of the SRF cavity and components;

Document results through tech notes, journal papers and conference papers; present results at team meetings, project meetings and conferences;

Plan, coordinate and/or complete small projects independently, or as part of a team.



1. Education, Certifications and Experience

a) Relevant PhD degree or equivalent b) Completion of a post doc in a closely related field or equivalent experience.

2. Knowledge, Skills, Abilities
a) Proven experience and ability with at least one RF simulation tool, such as CST, ACE3P, COMSOL, HFSS, etc., is required.
b) Experience with multi-physics simulation methods and codes and multi-variate optimization techniques will be a plus.
c) Demonstrated practical experience of accelerator component R&D and testing such as lab work, bench measurement, vertical test etc., competence in RF measurements using equipment such as network analyzer, spectrum analyzer, TDR, etc
d) Basic understanding of beam dynamics and general principles of accelerators, especially the storage ring colliders, as pertains to
RF system specification and design
e) Experience with RF cavities and components fabrication and processing, especially chemical processing and surface treatments for SRF \
cavities such as BCP, EP, furnace treatments, thin film coatings, etc., will be a plus
f) Proven ability to complete self-directed projects and tasks successfully and on time.
g) Able to communicate clearly in writing (e.g. email, memos, explanations, drawings) and explain work to his/her supervisor and others in
the group
h) Maybe called on to represent work associated with specific projects at professional meetings and present a proven record of journal and conference publications and documentation of results   
i) Interacts well with cross-disciplinary work groups and a wide variety of partners, vendors etc.

Travel may be required to attend EIC collaboration meetings, conferences, workshops and schools. Occasional off-shift work may be required for testing, commissioning or accelerator operations.
