Reactor Antineutrino Spectral "Bump": Cumulative Fission Yields of Irradiated U-235 and Pu-239 Measured by HPGe Gamma-Ray Spectroscopy
Samuel Kim, C. J. Martoff, Michael Dion +1
Recent measurements of the reactor antineutrino emission show that there exists a spectral excess (the "bump") in the 5-7 MeV region when compared to the Huber-Muller prediction ba…
Maximum Likelihood Spectrum Decomposition for Isotope Identification and Quantification
J. T. Matta, A. J. Rowe, M. P. Dion +4
A spectral decomposition method has been implemented to identify and quantify isotopic source terms in high-resolution gamma-ray spectroscopy in static geometry and shielding scena…
A Pair Production Telescope for Medium-Energy Gamma-Ray Polarimetry
Stanley D. Hunter, Peter F. Bloser, Gerardo O. Depaola +10
We describe the science motivation and development of a pair production telescope for medium-energy gamma-ray polarimetry. Our instrument concept, the Advanced Energetic Pair Teles…
A benign, low Z electron capture agent for negative ion TPCs
C. J. Martoff, M. P. Dion, M. Hosack +2
We have identified nitromethane (CHNO) as an effective electron capture agent for negative ion TPCs (NITPCs). We present drift velocity and longitudinal diffusion measureme…
On the Mechanism of Townsend Avalanche for Negative Molecular Ions
M. P. Dion, C. J. Martoff, M. Hosack
Time projection chambers drifting negative ions (NITPC) instead of electrons have several advantages. A NITPC can operate at very high reduced drift fields without diffusion runawa…
