Knecht,Angela Papa,Randolf Pohl,Maxim Pospelov,E. Rapisarda,Peter Reiher,Narongrit Ritjoho,S. Roccia,Nathal Severijns,A. Skawran,S. M. Vogiatzi,F. Wauters,Lorenz Willmann,A. Amato +24 more
TL;DR: In this article , a study conducted at the Paul Scherrer Institute (PSI) demonstrates that the absence of any beam time-structure leads to low pile-up events and a high signal-to-noise ratio (SNR) with less than one hour acquisition time per sample or data point.

TL;DR: In this article, the authors present the results of these campaigns, and the improvement the correction of this effect brings to the neutron electric dipole moment measurement, and evaluate and correct that effect, offline measurements of the field nonuniformity were performed during mapping campaigns in 2013, 2014 and 2017.

TL;DR: In this paper , the authors used repeated transfer reactions taking place inside a 100 bar hydrogen gas cell with an admixture of 0.25% deuterium to reduce the amount of target material needed while still offering an adequate efficiency.
