The mission of the Computing and Engineering for Physics Applications Department (CEPA) is to provide design, implemention, maintenance and project management support for software and hardware systems for HEP and Astrophysics experimentalists and phenomenologists. Software systems include real-time software for electronic systems, libraries and tools for physics applications. Hardware systems include board and system level hardware and firmware, and infrastructure electronics.

GOALS

The CEPA Department responsibilities are organized into four areas (Groups):

The Electronic Systems Engineering Group (ESE) provides FNAL with complete electronic engineering services for experiments, accelerator upgrade, future accelerator research, and R&D programs. More specifically, the current responsibilities include:

1. Provide engineering support to running experiments, collider or fixed target, involving module diagnosis, repair, enhancements, upgrades and technical assistance.

2. Advance R&D projects aimed at future experiments and general research into new technology that could be applied to Astrophysics and HEP instrumentation and accelerator technology and instrumentation.

3. Provide support of general Computing Division projects advancing Lab goals, in particular continued direct collaboration with the PREP equipment pool and hardware support of Division software efforts toward experimental needs.

The Applied Physics Software Group (APS) comprises two subgroups: Scientific Library Development (SLD) and Root (ROOT). The SLD Group develops HEP-specific software libraries and supplies consulting expertise, design assistance, and implementation effort for high- priority projects. Current responsibilities include Mathematical libraries for LCG MathCore and other HEP uses, and key participation in providing the CMS EDM and framework design and implementation. In addition, this group has responsibility for C++ language support, including presenting tailored courses and influencing the C++ standard in directions useful to HEP. The ROOT Group participates in ROOT product development, with particular emphasis on needs of FNAL physicists, and provides ROOT user support. An equally important aspect of the APS mission is to make available for priority "special projects" the development expertise present to handle these responsibilities. Current examples of such projects include grid accounting and optimization of Lattice QCD software.

The Online and Analysis Software Group (OAS) consults on, develops, and supports online software and hardware and online specific analysis tools for the current and future FNAL experiments. Specifically the Group supports online systems and the Control Room Logbook, an electronic logbook. The Group also develops software tools, hardware, and instrumentation for the Accelerator Division and is involved in support of future accelerator initiatives and remote operations.

The Physics Simulation and Modeling Group (PSM) supports simulations activities relevant to current and future Fermilab projects, by providing expertise in detector and physics modeling tools. The Group concentrates on support and development of physics generators for Run II and future energy frontier experiments, as well as on GEANT4 based detector simulation applications related to future experiments such as CMS. The development and maintainance of physics libraries related to simulations, such as HepMC and HepPDT, are also part of the PSM efforts. Finally, the Group is participating in the development of the hardware and software infrastructure for the Lattice QCD cluster.
