TL;DR: The fission Time Projection Chamber (fissionTPC) as mentioned in this paper is a two-chamber MICROMEGAS TPC designed to make precision cross-section measurements of neutron-induced fission.
Measurement of radiative capture resonance energies with an extended gas target
D. A. Hutcheon,Chris Ruiz,Jennifer Fallis,John D'Auria,Barry Davids,U. Hager,L. Martin,D.F. Ottewell,S. Reeve,S. Reeve,A. Rojas +10 more
TL;DR: The DRAGON facility for the study of radiative capture reactions has an extended gas target, surrounded by an array of BGO detectors as mentioned in this paper, where the distribution of detected gamma rays amongst the segmented array permits an estimate of the reaction position and consequently of the resonance energy.

Measurement of Radiative Proton Capture on F-18 and Implications for Oxygen-Neon Novae
C. Akers,C. Akers,Alison Laird,B. R. Fulton,Chris Ruiz,D. W. Bardayan,L. Buchmann,G. Christian,Barry Davids,Luke E. Erikson,Jennifer Fallis,U. Hager,D. A. Hutcheon,L. Martin,A. St. J. Murphy,K. J. Nelson,A. Spyrou,C. Stanford,D.F. Ottewell,A. Rojas +19 more
TL;DR: The first successful direct measurement of the 18F(p,γ)^19Ne reaction is reported, and the strength of the 665 keV resonance is found to be over an order of magnitude weaker than currently assumed in nova models.
Beam suppression of the DRAGON recoil separator for 3He(α, γ)7Be
S. Sjue,B. S. Nara Singh,P. Adsley,L. Buchmann,M. Carmona-Gallardo,Barry Davids,Jennifer Fallis,B. R. Fulton,N. Galinski,N. Galinski,U. Hager,Michael Hass,D. Howell,D. Howell,D. A. Hutcheon,Alison Laird,L. Martin,D.F. Ottewell,S. Reeve,S. Reeve,Chris Ruiz,Götz Ruprecht,S. Triambak +22 more
TL;DR: In this article, the DRAGON recoil separator was used to measure the absolute cross-section of the radiative capture reaction at the focal plane of the separator, which was shown to be background free.

First measurement in the Gamow window of a reaction for the γ-process in inverse kinematics: 76Se(α,γ)80Kr
Jennifer Fallis,C. Akers,C. Akers,Alison Laird,Anna Simon,A. Spyrou,G. Christian,D. Connolly,U. Hager,D. A. Hutcheon,A. Lennarz,Patrick O'Malley,S. J. Quinn,J. Riley,A. Rojas,Chris Ruiz,M. Williams,M. Williams +17 more
TL;DR: In this paper, the first cross section measurements of the 76Se( α, γ )80Kr reaction were performed in inverse kinematics in the energy region of the photo-disintegration pathway and compared with cross sections calculated using Hauser-Feshbach codes talys, non-smoker, and smaragd.
