Nuclear Photo Electron Avalanche Cell, Year 2 (NPEAC)

(1) Installation of a 300 keV X-ray source; (2) Mapping the emission potentials of lanthanides and other high Z materials; (3) Theoretical study for IB transitions, density functional analysis, and cross section analysis; (4) NPEAC device design (TRL 4); (5) Collaboration with DoE for using gamma ray sources. The NTAC is a new concept that offers significantly greater power density than current state of the art thermoelectric generators. The conventional energy conversion systems rely only on the electrons in valence band. The NPEAC liberates and uses a huge number of electrons in the intra-band for power generation resulting in significantly higher power density capability.
