Nicolae Podaru is presently working for High Voltage Engineering Europa (HVE), one of the main manufacturers of complete electrostatic particle accelerator, used in various research fields, including and not limited to Accelerator Mass Spectrometry, Ion Beam Analysis, Ion Beam Material Modification, etc. His Master of Science degree was obtained in Plasma Physics¸ and he obtained his Ph.D. in Solid State Physics, at the Technical University in Eindhoven, The Netherlands. He joined HVE in 2009 as an Accelerator Physicist, and afterwards became the Manager of the Physics department. Within the Technology Department of HVE, he has contributed to the accelerator technology development, including ion source technology, linear electrostatic technology, various beam guiding elements design, resistive magnet design, etc. A part of his work has been published in peer reviewed scientific publications. During his class, he will introduce you into the world of solid state particle accelerator systems (based on the so-called parallel fed Cockroft-Walton voltage generation system), “ion sourcery” (from charge exchange to direct negative extraction and ion beam brightness) and modern design tools used in development/engineering of resistive magnets and microprobe quadrupole systems for MeV micro beams.



Dr. Eric Alderson is an Accelerator Physicist and Senior Project Manager at National Electrostatic Corp.  He has installed accelerators in four countries and contributed to a variety of designs.  Besides experience with accelerator physics, he has professional experience working in plasma physics, diagnostics, and fusion technology.

In an era of accelerators producing TeV collisions, it can be easy to overlook electrostatic accelerators as old technology, however, demand for electrostatic accelerators has sustained an industry for over 60 years, and indications are demand will continue.  Despite beam energy limitations, electrostatic accelerators outperform alternative accelerator technologies in specific ways that make them attractive tools for a wide variety of applications.  The first half of this talk we will discuss the advantages of electrostatic accelerators and the roles that they fill in contemporary research.

Next, we will discuss the work National Electrostatic Corp. (NEC) is doing to fill the need for electrostatic accelerators.  We will review NEC's latest completed projects, ongoing R&D, and projects currently underway.  This will allow us to touch on a variety of the currently relevant applications of electrostatic accelerators, as well as present NEC's experience building scientific apparatus to specification.

 “The Relevance of Electrostatic Accelerators in Industrial and Research Applications and Recent Developments at NEC”

Wang will teach a two-hour session class on “Ion Beam Analysis”, including where is IBA’s place in analysis universe; fundamentals of ion-solid interactions relevant to IBA (kinematics, cross-sections, ion stopping); Overview of common IBA techniques (RBS, ERD, NRA, PIXE, and Channeling).



Dr. Brian Roeder

Accelerator Physicist

Cyclotron Institute

Texas A&M University

Dr. Brian Roeder received his PhD in nuclear physics from Florida State University in 2006. During his graduate studies, he worked extensively with the 9 MV FN Tandem Van de Graff accelerator at Florida State University. This work included tuning beams for nuclear physics experiments and maintenance of the accelerator and ion sources. Following his graduate and postdoctoral studies, Dr. Roeder became an Accelerator Physicist at the Cyclotron Institute at Texas A&M University in 2012. At Texas A&M University, Dr. Roeder works with two cyclotrons, the K150 and the superconducting K500 cyclotron, to produce beams for nuclear physics and applied physics research. Dr. Roeder's current research includes the development of proton and heavy-ion beams with the K150 cyclotron for applied physics, the development of high intensity ion beams, and the re-acceleration of stopped radioactive ion beams for nuclear physics produced from the Texas A&M University Light Ion Guide project.

Cyclotrons: Beam Production and Application - Roeder will present the basic operation of cyclotrons that are in operation, the ion sources that are used to produce the beams, the optics magnets that guide the beam to the applications, and the advantages and disadvantages of cyclotrons for nuclear and applied physics.
