The Thomas Jefferson National Accelerator Facility invites applications for
the position of a CLAS Data Acquisition System Physicist in the Hall B
Group of the Physics Division. The CLAS detector in Hall B at Jefferson
Lab is instrumented with wire chambers, scintillation counters, and gas
Cerenkov detectors. The data acquisition and control of the detector
components is accomplished with a cluster of SUN Unix processors in the
control room and with about 30 distributed controllers/processors in the
hall connected by Ethernet. The Hall B Group is looking for an individual
who will be responsible for data acquisition related hardware and software.
The data acquisition framework is provided by the in-house CODA group, and
CLAS specific software must be added to match the detector components. The
successful candidate must have experience with digitizing and control
electronics in Fastbus, VME, and Camac crates as well as with embedded
processors, workstations, and multi-processor machines operating as Unix or
Unix-like platforms. It is required that the incumbent be able to carry a
project through all phases of design, implementation, and testing, and be
very familiar with testing/debugging hardware, and communicate well with
the CLAS on-line group, the CODA group and representatives of the various
detector components.
A Ph.D. in Experimental Physics is required, with at least three years
experience with hardware implementation and software development for
complex experimental physics detectors. A proven track record of
significant contributions to on-line software and hardware projects; in
particular, expertise with Fastbus, VME, and Camac protocols, with time and
pulse height digitizing units as well as with real-time event-driven
processing and communication among real-time processes. A good working
knowledge of UNIX. Fluent in Fortran and C as well as several scripting
languages, such as Perl, Tcl/Tk, csh, etc. Knowledge of C++ and experience
with HTML documents desirable. Applicants should submit a CV, including
the names of at least three references, to: TJNAF, Attn: Employment
Manager, 12000 Jefferson Ave, Newport News, VA 23606. U.S.A
