The position will be formally handled by Argonne National Laboratory, with the majority of work to be done at Lawrence Berkeley National Laboratory, Berkeley, California.

Date: January 16, 2013. Applications accepted until position filled.

As Postdoctoral Fellow, the employee will be engaged in developing a viable thin film solution to superconducting radio-frequency (SRF) cavities for accelerator applications. The employee will have a critical role in applying high power impulse magnetron sputtering (HIPIMS) to fabricate films and multilayers of thin films exhibiting superconducting properties with goal to (a) replace bulk niobium cavities and (b) explore thin film options to exceed the limits set by using bulk niobium for SRF cavities. The task involves operation and improvement of existing, dedicated HIPIMS plasma deposition equipment located at Lawrence Berkeley National Laboratory.
Additionally, the employee will be directly involved in the detailed and careful preparation of substrates and the characterization of materials and superconducting and radio-frequency properties of the films and multilayers obtained. Substrates will include planar coupons, dummy cavities, and actual SRF cavities. Preparation and characterization will be done across two or more National Laboratories, and the task requires frequent communication between collaborators and occasional travel.
The employee is expected to contribute to new scientific results which will be disseminated in conference contributions and peer-reviewed scientific journal publications. The employee is expected to regularly contribute and occasionally lead the publication process as author or co-author.
The employee is expected to complete all required safety training and perform work in safe manner compliant with the Laboratory’s safety policy.


As a Postdoctoral Fellow, he/she must
• work with and improve thin film deposition equipment based on HIPIMS technology
• prepare substrates, develop surface pretreatment recipes, perform deposition of superconducting films and multilayers using HIPIMS equipment
• coordinate the characterization of film properties and SRF properties; some (or even most) to be done by the employee himself/herself
• learn additional skills to be able to address the quite diverse requirements of conducting experiments though automation and feedback control (Matlab, LabView), optimization of processes, materials characterization at room and cryogenic temperatures, etc.
• be proactive in identifying suitable techniques and approaches
• regularly communicate with many co-workers on the various aspects of the tasks; those coworkers are local or at other facilities
• write reports and publications
• adhere to all required safety standards
• play an active role in the further development of tasks and research strategy.


o work with students and laboratory affiliates (guest scientists).


Environment, Health and Safety: Describe duties and responsibilities associated with both classification level and specific position.

Follow safe practice in the laboratory and office, paying particular attention to legal and Laboratory health, safety and environmental regulations in the execution of all work.
