Energy Storage
Direct Energy Extraction:
Capture and Conversion of Energy
from Isotopes and Nuclear Isomers
BTG researches high density energy storage in the form of nuclear isomers.
Nuclear isomers are of special interest as energy storage devices because they
have the potential to store energy with higher energy density than most other
devices and if their energy can be released by excitation (triggering) by an
external source, they can provide on-demand high power.
Both nuclear isomers and radioactive isotopes release their energy at a specific
rate by emission of gamma rays and/or charged particles. To use radioactive
materials as high energy density devices for remote applications depends on
having a means to capture and convert the energy to useful form such as direct
voltaic, thermal voltaic, chemical or mechanical. Whether or not isomers can be
triggered, it is useful to examine how isotope and isomer decay energy can be
captured and converted to one of these forms. BTG examines means to capture and
convert decay energy from triggered isomers and ordinary radioisotope sources.

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.
