J. Paul Farrell, Ph.D. Physics, President


From left: Dr. J. Paul Farrell and Dr. James R. Powell

Dr. Farrell received his Ph.D. in Theoretical Nuclear Physics from the University of Pittsburgh and his B.Sc. in Physics and Mathematics from The University of Chicago. Dr. Farrell's professional experience has been principally with the design and applications of electron and ion accelerators for research and industry. He worked for 12 years with Radiation Dynamics Inc. (RDI), where he was responsible for beam line design, systems design, installation and demonstration of the first high power (150 kW) electron accelerator system for radiation sterilization of medical products. He worked closely with the Food and Drug Administration and Association for Advancement of Medical Instrumentation (AAMI) to establish the first guidelines for use of electron radiation for medical device sterilization. While at RDI, he obtained patents for a method to improve the lifetime of tritium targets used for neutron cancer therapy and for a method of regulating the energy of a dc electron accelerator during high current pulsed operation. He joined General Ionex Corp. as Head of Physics in 1982 where he participated in the development of the Tandetron accelerator and he participated in the development of a high energy ion implanter based on a tandem accelerator design.

In 1987, Dr. Farrell founded Brookhaven Technology Group, Inc., a research and development company that designs, tests and integrates industrial accelerator systems and components. Dr. Farrell is a member of the Association for Advancement of Medical Instrumentation (AAMI). At Brookhaven Technology Group, Inc, Dr. Farrell was a lead investigator in the design and testing of a 5 MeV laser triggered, photo excited pulsed electron gun that produces sub-nanosecond voltage pulses and currents up to 600 A for 100 ps at a pulse repetition rate of 1/10th Hz.

Dr. Farrell served as Chairman of the Industrial Applications and Materials Effects Subcommittee of the Council on Ionization Radiation Standards and Measurements (CIRMS), an organization that works with the U.S. National Institute of Standards and Measurements (NIST) to define National Needs in the Ionizing Radiation Program at NIST. He also served as co-chair of the Working Group on Electron Beam Sterilization of Medical Devices from 1985 to 1989 that wrote the first industry wide Guideline on Electron Beam Sterilization of Medical Products. Later he served on the ISO committee on Radiation Sterilization of Medical Products.

BTG News

June 22, 2006

Brookhaven Technology Group, Inc., was awarded a new Phase I SBIR grant to develop an advanced surface plasma source for reliable long time production of H¯/D¯ beams with high brightness and high pulsed current and average intensity up to ~20mA. The principal goal of this project is to develop a high performance, long lifetime surface plasma H¯ source by using a unique new highly efficient helicon discharge plasma generator. The plasma flux formed by this helicon discharge will be used for surface plasma generation of H¯.

In Phase I, simulations of plasma generation, ion/atom conversion, and H¯/D¯ surface-plasma generation will be carried out to prove the feasibility of this new approach. The discharge system will be studied, beam extraction and formation including electron suppression will be designed, and computer simulated.

This is the third Phase I SBIR awarded to BTG for development of negative ion source technology. In previous years the company received Phase I and Phase II funding to design, build, and test a high brightness, long lived source of heavy negative ions (HNIS). This source is now available for commercialization. More information about the HNIS is available on this website.
