DIRECTED ENERGY PROFESSIONAL SOCIETY


2002 Directed Energy Symposium Short Courses
12 November 2002 Monterey, California

These short courses were offered in conjunction with the Fifth Annual Directed Energy Symposium. Continuing Education Unit (CEU) credits were offered for completion of these DEPS short courses.


Free-Electron Laser Short Course

Instructors:

  • Prof. Patrick O'Shea, University of Maryland
  • Prof. William Colson, Naval Postgraduate School
  • Dr. George Neil, Thomas Jefferson National Accelerator Facility
This Free-Electron Laser (FEL) short course will offer a general introduction to FELs including basic physics and technology concepts, major worldwide projects, and applications. Design considerations of high average power FELs will be discussed, covering electron beam, optics and undulator designs. The course will end with a practical implementation of high average power FELs, including overall system configuration, systems efficiency, power sources, control, and operation.

Schedule:
0800   FEL Accelerator Design Considerations (O'Shea)
1000   Break
1030   FEL Undulator Design Physics (Colson)
1230   Lunch
1330   FEL Systems Design (Neil)
1530   Adjourn

High Power Microwave Technology Short Course

Instructors:

  • Prof. James Dickens, Texas Tech University
  • Dr. James Benford, Microwave Sciences, Inc.
  • Prof. Michael Morgan, Naval Postgraduate School
This course provides a three-part tutorial on state-of-the-art high power microwave technologies. Via these three parts, attendees will be exposed to both the historical perspective as well as the present state of the various components that comprise a high power microwave system. Each of the following will be covered in an individual two-hour block: the development of pulsed power and its applications to microwave generation, narrowband high power microwave source technology, and the fundamental principles of antennas for high power microwave sources. Attendees should have a background in science or engineering at the B.S. level to receive the most benefit from the course.

Schedule:
0800   Pulsed Source Technology (Dickens)
1000   Break
1030   Narrow Band HPM (Benford)
1230   Lunch
1330   HPM Antenna Design Considerations (Morgan)
1530   Adjourn

Beam Control Short Course

Instructors:

  • Dr. Paul Merritt, The Boeing Company SVS, Inc.
  • Dr. Tim Howard, The Boeing Company SVS, Inc.
  • Mr. Dick Brunson, The Boeing Company SVS, Inc.
This class will present the basic material needed to design and analyze a laser pointing and tracking system from target acquisition through fine pointing. The topics will include performance equations, radiometrics, the acquisition process, image processing, track algorithms, and gimbal pointing. The course will stay focused on technical topics and useful equations.

Schedule:
0800   Introduction (Merritt)
0900   Radiometry (Howard)
1000   Break
1030   Sensors (Howard)
1130   Acquisition & Tracking (Brunson)
1230   Lunch

1430   Kalman Filtering & V/D Tracking Effects (Merritt)
1530   Adjourn

Laser Propagation and Materials Interaction Short Course

Instructors:

  • Prof. Donald Walters, Naval Postgraduate School
  • Dr. Phillip Sprangle, Naval Research Laboratory
  • Dr. Jorge Beraun, Air Force Research Laboratory
This course will provide an introduction of atmospheric laser propagation by first describing the principles of scattering, absorption, turbulence and wind for typical laser beams of greater than 10-10 second duration. Next, propagation processes associated with short, intense laser pulses will be discussed. The diverse linear and nonlinear effects on optical propagation will be described. Finally, the processes of laser beams interaction with solid matter will be presented.

Schedule:
0800   Classical Laser Propagation (Walters)
1000   Break
1030   Short Pulse Propagation (Sprangle)
1230   Lunch
1330   Laser Interaction Physics (Beraun)
1530   Adjourn

Introduction to Directed Energy and Current Technical Issues Short Course

Instructors:

  • Dr. Al Kehs, Army Research Lab
  • Mr. John Albertine, Independent Consultant, Navy DEW program
This course will provide an introduction to the field of directed energy weapons. It is geared to the undergraduate student, graduate student or engineer/scientist entering the DE field.

The introduction to HPM weapons will follow the history of early excitement and crude experiments to the more refined modeling and simulation-based programs that characterize current activity. Generic effects and applications will provide perspective for discussions on technology that will include both narrow band and ultra-wide band sources, antenna fundamentals, propagation, diagnostics, modulators, power sources, and an introduction to hardening devices and techniques. Current modeling and simulation tools will also be presented as appropriate. The HEL field will be introduced using an interleaving of history, technical requirements, and accomplishments. The basic attributes of HEL weapons will be covered, leading into discussions of laser-material interaction, lethality, potential applications, system requirements, laser power scaling, propagation and beam control. Current technical issues and areas of research emphasis will be highlighted.

Schedule:
0800   High Power Microwave Systems (Kehs)
1000   Break
1030   High Energy Laser Systems (Albertine)
1300   Adjourn
