A Starry Byte — proton beam measurements of single event upsets and other radiation effects in ABCStar ASIC Versions 0 and 1 for the ITk strip tracker / Basso, M.J. (Toronto U.) ; Fernández-Tejero, J. (Simon Fraser U. ; TRIUMF) ; Gallop, B.J. (Rutherford) ; Greig, G. (Simon Fraser U.) ; John, J.J. (CERN) ; Keener, P.T. (Pennsylvania U.) ; Krizka, K. (LBL, Berkeley) ; Leitao, P.V. (CERN) ; Norman, B. (Carleton U.) ; Phillips, P.W. (Rutherford) et al.
Single Event Effects (SEEs) - predominately bit-flips in electronics caused by particle interactions - are a major concern for ASICs operated in high radiation environments such as ABCStar ASICs, which are designed to be used in the future ATLAS ITk strip tracker. The chip design is therefore optimised to protect it from SEEs by implementing triplication techniques such as Triple Modular Redundancy (TMR). [...]

Threshold bounce — occupancy-dependent modulation of the discriminating threshold in silicon detectors / Basso, M.J. (TRIUMF ; Simon Fraser U.) ; Buchanan, E. (CERN) ; Gallop, B.J. (Rutherford) ; John, J.J. (CERN ; Oxford U.) ; Kaplon, J. (CERN) ; Keener, P.T. (UPenn, Philadelphia) ; Phillips, P.W. (Rutherford) ; Poley, L. (TRIUMF ; Simon Fraser U.) ; Sawyer, C.A. (Rutherford) ; Sperlich, D. (Freiburg U.) et al.
The front-end electronics of silicon detectors are typically designed to ensure optimal noise performance for the expected input charge. A combination of preamplifiers and shaper circuits result in a nontrivial response of the front-end to injected charge, and the magnitude of the response may be sizeable in readout windows subsequent to that in which the charge was initially injected. [...]

Single event effect in ABC ASICs for ITk strip upgrade / Peng, Shaogang (Tsinghua U., Beijing ; Beijing, Inst. High Energy Phys.) ; Basso, Matthew (TRIUMF ; Simon Fraser U.) ; Chen, Xin (Tsinghua U., Beijing) ; Dandoy, Jeff (Carleton U.) ; Gallop, Bruce (Rutherford) ; John, Jaya John (U. Oxford (main)) ; Jing, Hantao (CAS, IHEP, Dongguan) ; Keener, Paul (UPenn, Philadelphia) ; Leitao, Pedro (CERN) ; Lu, Weiguo (Beijing, Inst. High Energy Phys. ; CUST, SKLPDE) et al.
This is the first study of the ABCStar V1 chips with an 80 MeV proton beam from CSNS. The ITk strip upgrade project utilizes the custom ABCStar ASIC, employing Triple Modular Redundancy technology to enhance its resistance to Single Event Effects caused by radiation. [...]

A gaseous RICH detector for SiD or ILD / Basso, Matthew J. (TRIUMF ; Simon Fraser U.) ; Cairo, Valentina M.M. (CERN) ; Damerell, Chris (Rutherford) ; Su, Dong (SLAC ; Stanford U., Phys. Dept.) ; Schwartzman, Ariel G. (SLAC ; Stanford U., Phys. Dept.) ; Va'vra, Jerry (SLAC ; Stanford U., Phys. Dept.)
This paper describes a preliminary study of a gaseous Ring Imaging Cherenkov (RICH) system capable of discriminating between kaons and pions at high momenta -- up to 50 GeV/c -- and thus enhancing particle identification at future colliders. The system possesses a compact design, facilitating easy integration into existing detector concepts. [...]

Improved search for two body muon decay ${\mu}^+{\rightarrow}e^+X_H$ / PIENU Collaboration
Charged lepton flavor violating muon decay ${\mu}^+{\rightarrow}e^+X_H$, where $X_H$ is a massive neutral boson, was sought by searching for extra peaks in the muon decay ${\mu}^+{\rightarrow}e^+{\nu}\bar{\nu}$ energy spectrum in the $m_{X_H}$ mass region $47.8-95.1$ MeV/$c^2$. No signal was found and 90% confidence level upper limits were set on the branching ratio ${\Gamma}({\mu}^+{\rightarrow}e^+X_H)/{\Gamma}({\mu}^+{\rightarrow}e^+{\nu}\bar{\nu})$ at the level of $10^{-5}$ for this region..

Search for the rare decays $\pi^+ \to \mu^+\nu_\mu\nu\bar\nu$ and $\pi^+ \to e^+\nu_e\nu\bar\nu$ / PIENU Collaboration
The rare pion decays ${\pi}^+{\rightarrow}{\mu}^+{\nu}_{\mu}{\nu}\bar{\nu}$ and ${\pi}^+{\rightarrow}e^+{\nu}_{e}{\nu}\bar{\nu}$ are allowed in the Standard Model but highly suppressed. These decays were searched for using data from the PIENU experiment. [...]

High-precision half-life determination of $^{14}$O via direct $\beta $ counting / Sharma, S. (Regina U.) ; Grinyer, G.F. (Regina U.) ; Ball, G.C. (TRIUMF) ; Leslie, J.R. (Queen's U., Kingston) ; Svensson, C.E. (Guelph U.) ; Ali, F.A. (Guelph U. ; Sulaimaniya U.) ; Andreoiu, C. (Simon Fraser U., Dept. Chem.) ; Bernier, N. (TRIUMF ; British Columbia U. ; Western Cape U. ; Zululand U.) ; Bhattacharjee, S.S. (TRIUMF) ; Bildstein, V. (Guelph U.) et al.
The half-life of the superallowed Fermi $\beta^+$ emitter $^{14}$O was determined to high precision via a direct $\beta$ counting experiment performed at the Isotope Separator and Accelerator (ISAC) facility at TRIUMF. The result, $T_{1/2}$($^{14}$O) = 70619.2(76) ms, is consistent with, but is more precise than, the world average obtained from 11 previous measurements. [...]

Search for Heavy Neutrinos in $\pi \to \mu\nu$ Decay / PIENU Collaboration
Heavy neutrinos were sought in pion decays $\pi^+ \rightarrow \mu^+ \nu$ by examining the observed muon energy spectrum for extra peaks in addition to the expected peak for a massless neutrino. No evidence for heavy neutrinos was observed. [...]

Design and performance of a novel low energy multispecies beamline for an antihydrogen experiment / ALPHA Collaboration
The ALPHA Collaboration, based at the CERN Antiproton Decelerator, has recently implemented a novel beamline for low-energy ($\lesssim$ 100 eV) positron and antiproton transport between cylindrical Penning traps that have strong axial magnetic fields. Here, we describe how a combination of semianalytical and numerical calculations were used to optimise the layout and design of this beamline. [...]
