2 YEAR TERM POSITION
POSITION POSTED:OCTOBER 14, 2015
SALARY RANGE: $51,500 - $77,300

Hall B at Jefferson Lab has an opening for a Postdoctoral Fellow with expertise in electromagnetic nuclear or particle physics. Hall B is in the process of finalizing its upgrade with the completion of the CLAS12 detector system, a DOE funded part of the energy upgrade of the Jefferson Lab CEBAF accelerator to 12 GeV beam energy and the construction of new experimental equipment that broadens the science reach of the Lab. CLAS12 is expected to be ready for operation by the end of 2016 and first physics beam is expected in early 2017.

A broad physics program has already been approved that uses the CLAS12 detector covering programs to study the nucleon structure in a multi-dimensional representation by measuring deeply virtual exclusive processes to access the generalized parton distribution (GPDs) and transverse momentum-dependent distributions (TMDs). Other programs include the search for hybrid meson, the study of nucleon resonances at short distances, the measurement of polarized parton distributions function at very high xB using polarized beam and polarized hydrogen and deuterium targets as well as the short distance behavior of nuclear correlations in polarized nuclei. The postdoctoral fellow will work along side the staff scientists on the preparation and execution of the CLAS12 experiment, on the data calibration and physics analysis. It is expected that the successful candidate will play a major role in the development of on-line and off-line monitoring and data calibration tools, and participate in the development of offline reconstruction software. The candidate is expected to lend general support to the joint efforts of the CLAS collaboration and its new CLAS12 detector systems. Hall B also offers wide opportunities for physics analysis of data already taken with the CEBAF Large Acceptance Spectrometer (CLAS) at beam energies of up to 6 GeV, and the preparation of new experimental proposals to be run with the upgraded CLAS12 detector. There are also opportunities for involvement in the development of the science program and the detector development for the proposed Electron Ion Collider (MEIC). Involvement at a modest level in this initiative is encouraged.

The position will be available immediately for a 2 year term.

Position Requirements

A PhD in electromagnetic nuclear or particle physics or an equivalent combination of education and specific training. Experience with the operation of large spectrometer experiments and demonstrated ability to pursue physics data analysis are required. Therefore, software experience is important, a demonstrated knowledge of C++ and Java programming languages is a plus.

Applicants should send a curriculum vitae and arrange to have letters from two references sent to: Linda Ceraul (ceraul@jlab.org).
