IVEC-IVESC 2012 will feature several fascinating plenary talks given by world renowned speakers. Take a minute to look over the talks listed below!

Tizard's Mission and the Cavity Magnetron

Mr. Stephen Phelps, Author, "The Tizard Mission"

In August 1940, Sir Henry Tizard led a team of scientists from the U.K. on a mission to the U.S. which was the springboard for critical new weapons and defense systems for World War II based on the cavity magnetron, recently developed in Britain.

Stephen Phelps is a writer, television producer and broadcaster. Educated at Oxford University, he began his broadcasting career with BBC Radio, moving to BBC TV for the beginning of Daytime TV. He joined BSB for the start of satellite television in the UK as Editor of entertainment and movie programmes. Moving to become Director, Hong Kong, for BBC World Service Television overseeing the start of their Asian service on Star TV.

He then spent twelve years running his own TV production company, Just Television, where he directed and produced a wide range of programmes for most broadcasters in the UK, winning the Royal Television Society's inaugural Specialist Journalism Award in 1999, and the New York Festival World Gold Medal for News Investigative Reports, 2001. At Just Television he specialised in investigative programmes in the field of law, justice and policing, in particular Trial and Error for Channel 4 which exposed and investigated major miscarriages of justice. This built on prior work at the BBC as Producer of Rough Justice, and Deputy Editor of Watchdog.

In recent years he has been working occasionally with Al Jazeera International, most recently launching The Stream, an innovative live daily programme covering news and current affairs through social media.

Currently Stephen is concentrating on writing. His recent successes include major radio drama fro the BBC and he has just had his first book, The Tizard Mission, published in the USA and Great Britain.

Stephan lives in London, UK, and Sarnano, le Marche, Italy.

The Kepler Mission: Zeroing in on Habitable Earths

Dr. Douglas Caldwell, Principal Investigator, SETI Institute, NASA Ames Research Center

NASA's Kepler Mission's goal is determining the frequency of Earth-size planets in our Galaxy. Kepler is beginning the third year of the planned 3.5 years of data collection and has detected over 2,300 planet candidates, the first Earth-size planets, the first circumbinary planets, and over 360 multiple-planet systems.

Douglas Caldwell currently works for the SETI Institute at the NASA Ames Research Center and is a Co-Investigator and the Instrument Scientist for NASA's Kepler Mission. He began working on the Kepler Mission in 2001 and took on the position of Instrument Scientist in 2006. In this role, he helped define, conduct, and analyze pre-launch instrument tests, investigated anomalies, characterized the instrument performance, and generated calibration models and algorithms for use in data analysis. His current responsibilities include monitoring the health and performance of the Kepler photometer, updating calibrations, and tracking down instrument artifacts and their effects on the science data. Prior to working full-time on Kepler, Dr. Caldwell worked on two ground-based transiting exoplanet searches. The first, Vulcan, used a small refractor and a large-format CCD camera at Lick Observatory to search for Jupiter-size planets. Vulcan served as a test bed and training ground for Kepler hardware, software, and science operations. Dr. Caldwell was the principal investigator on the second survey, a Vulcan-like system deployed to the South Pole to take advantage of the long winter night. On this project he lead a small international team that designed, built, deployed, and operated an automated observatory located at the South Pole for two austral winters.

Dr. Caldwell received BS in Physics from Carnegie-Mellon University in 1986. He worked for a time as an electronics engineer for the US Navy in Pt. Hueneme, CA, where he supported testing and troubleshooting for a ship defense system. He returned to school and received his PhD in Physics from Rensselaer Polytechnic Institute in 1996, where he studied star formation using infrared and millimeter wave observations.

Saving Lives, Keeping Safe and Searching for Gold: The Electron Linear Accelerator Business

Dr. George A. Zdasiuk, Corporate Senior Vice President, CTO, and Director of the Ginzton Technology Center, Varian Medical Systems

This paper discusses the multi-billion dollar microwave electron accelerator business including applications in the fields of medicine, security, gold prospecting, inspection and industrial processes. Considerable synergy exists between microwave tubes and electron linear accelerators. Both play key roles in experimental physics labs, medical clinics, border crossings and industrial plants worldwide.

George Zdasiuk joined Varian in 1980 as a staff member in the technical research laboratory. He began assuming management responsibilities in 1985 and became director of Varian's Healthcare Technology Laboratory in 1990. Today, as director of the Ginzton Technology Center, Varian's R&D center, Zdasiuk is responsible for the company's research and new venture start-up activities. Zdasiuk holds a PhD in applied physics from Stanford University, as well as a master's degree in physics and a B.A.Sc degree in engineering science from the University of Toronto.

Compact Electron Accelerators Based on Lasers and Plasmas: Towards a 10 GeV Machine

Dr. Wim Leemans, Senior Scientist, Lawrence Berkeley National Laboratory

An overview will be presented of the research at LBNL towards making 'tabletop' accelerators. We have produced GeV electron beams from centimeter-scale accelerating structures and are developing a 10 GeV machine based on meter-scale device. The challenges towards their use for advanced light sources and colliders will be discussed.

Wim Leemans has been at LBNL since 1991 and is currently a senior scientist and Head of the LOASIS Program and Director of the BELLA Project that provides a Petawatt laser operating at 1 Hz. He obtained his PhD from UCLA in 1991 and received the '92 APS-DPP Simon Ramo for his dissertation on plasma beatwave acceleration related physics. His research interests have been and are on laser plasma accelerator science and hyperspectral radiation sources. In 1996 he was a co-recipient of the Klaus Halbach Award for demonstration of femtosecond x-rays from Thomson scattering. For his work in laser plasma acceleration he received the 2005 United States Particle Accelerator School Prize for Achievement in Accelerator Physics and Technology, Outstanding Performance Awards at LBNL in 2005 and 2006, the 2009 E.O. Lawrence Award from the DOE and the 2010 APS John Dawson Award for Excellence in Plasma Physics Research. He is a Fellow of both APS and IEEE. Three of his students have won outstanding dissertation awards (APS-DPP, APS-DPB and PJAS).

Much Ado About Nothing: Electron Sources and Transport in Vacuum

Dr. Kevin L. Jensen, Research Physicist, Naval Research Laboratory

Thermionic, Field, Photo, and Secondary emission processes affect vacuum transport characteristics and applicability to various Vacuum Electronic applications. Emission mechanisms will be related to desirable features and limitations of the beams produced in terms of current density, lifetime, space charge, beam halo, emittance, and response time.

Kevin L. Jensen received the B. S. degree in applied physics from Columbia University in 1981, and the M. S. and Ph.D. degrees in physics from New York University in 1984 and 1987, respectively. In 1987, he joined the Naval Research Laboratory as a National Research Council post-doc and in 1990, he became a Research Physicist for the Vacuum Electronics Branch for theoretical work on emission properties of electron sources. Since 2002 he has also been a Visiting Senior Research Scientist at the University of Maryland. His theoretical research concerns emission properties of electron sources, particularly cold cathodes and photocathodes, for rf amplifiers and Free Electron Lasers. In 2009, he was elected a Fellow of the American Physical Society for his work on electron emission physics.
