## Physics Division Mission

**The mission of the LBNL Physics Division is to discover the particles that compose the universe and to understand the forces that shaped the origin and fate of the universe.**
**We accomplish this through an integrated program of theory and experimental science that leverages the unique combination of scientific, engineering and computational resources of Berkeley Lab and the University of California**

## In support of this mission the Physics Division will

**Play a leadership role in particle physics experiments and observational cosmology through the development of new initiatives, through the design, construction and operation of new experiments and through the analysis of data from those detectors**
**Play a leadership role in formal and phenomenological particle physics theory and theoretical cosmology**
**Strengthen the university-based high energy physics program in the United States through our scientific collaborations, through a program of workshops and visitors and through access to leading-edge facilities.**
**Carry out long-term research and development to define the detector and computing technologies needed for  the future of the national high energy physics program**
**Provide service to the international high energy physics program through the compilation of high energy physics data and the publication of the *****Review of Particle Physics***
**Educate the next generation of scientific leaders through our graduate and undergraduate programs and through postdoctoral appointments, including strengthening the University’s physical science educational mission. **
**Communicate the accomplishments of the high energy physics program outside our high energy physics community and transfer our new technologies to other sciences and to the nation**
**Contribute to the national program through service on planning panels, advisory committees, program reviews, scientific societies, and University programs.**
**Provide a working environment that is nurturing and intellectually challenging and that respects the contributions of our diverse staff**
**Protect the safety and health of our employees and the natural environment through a proactive Environment, Health and Safety program**

## Back to the Future

***“******As we enter the 21st century, we have arrived at a special time in our quest to understand the universe... To realize many of these discoveries, it will be necessary to bring together the science of the very large - astronomy - with the science of the very small - particle physics.  No longer can one view the study of particle physics and deep space astronomy as separate and distinct.  Their futures and goals are now strongly intertwined.”***
**John Marburger, Feb. 2004, **
**cover letter for the Physics of the Universe Interagency Working Group Report**

**We are now faced with a revolution in our understanding of nature as profound as that initiated by Einstein’s *****annus irabilis***** in 1905.**

- Recharges (care and feeding: space, phones, electricity, computing) are non-trivial

## FY04 approximate use of funds

## Key Concepts and Challenges

- Participation in experiments from conception through sophisticated and refined data analysis
- Experiment and Theory - integrated and synergistic
- Campus connection- jointly address recruitment and retention issues for faculty in Particle and Astro Physics
- Infrastructure and partnerships across divisions in support of “big science”
- Compete for resources to initiate new programs, build and maintain national and international collaborations
- Resource management – biggest challenge is effective reporting and analysis at hierarchical levels; in a variety of formats;  for managers, investigators and sponsors

## e.g. - IceCube

- IceCube is a one-cubic-kilometer international high-energy neutrino observatory being built and installed in the clear deep ice below the South Pole Station.
- NSF initiative –  Major Research Equipment (MRE), lead US institution is University of Wisconsin
- FY04 funding request - $295.2M through FY2013. This includes construction and commissioning and four years of operation after construction.
- Subaward to LBNL, Nuclear Science WFO, with history in Physics and Nuclear Science – PI Robert Stokstad (NS), Project Manager Bill Edwards (ENG)
-  highly interdisciplinary with staff from Nuclear Science, Physics, Engineering and Computing Science
- We are entering Project Year 4, focused on construction and detector commissioning – LBNL proposed Scope of Work estimated at 8.2M$, XX FTE
- Basis of our participation is innovation in instrumentation, experience in development and commissioning of instrumentation and data acquisition components, study of neutrinos in both Physics and Nuclear Science divisions

## Ice Cube

- Prototype project – Antarctic Muon and Neutrino Detector Array - AMANDA
- constructing a radically different telescope, instead of sensing light, like all telescopes since the time of Galileo, AMANDA responds to a fundamental particle called a neutrino. Neutrino messengers provide a startling new view of the Universe. This was the first practical implementation of the generic ideas formulated many years ago, and re-introduced in late 80's with the twist of using Antarctic ice instead of water.
- Early LBNL LDRD support for innovation in instrumentation, tools for data acquisition
