The Performance and Long Term Stability of the D0 Run II Forward Muon Scintillation Counters [PDF]
Nuclear Instruments and Methods in Physics Research, Volume 753
(2014), pages 105-115, 2014 The performance of the D0 experiment forward muon scintillation counters system during Run II of the Tevatron from 2001 to 2011 is described. The system consists of 4214 scintillation counters in six layers. The long term stability of the counters amplitude response determined using LED calibration system and muons produced in proton-antiproton ...

Development of High Precision Timing Counter Based on Plastic Scintillator with SiPM Readout [PDF]
IEEE Trans. Nucl. Sci. 61, 2657-2666 (2014), 2014 High-time-resolution counters based on plastic scintillator with silicon photomultiplier (SiPM) readout have been developed for applications to high energy physics experiments for which relatively large-sized counters are required. We have studied counter sizes up to $120\times40\times5$ mm^3 with series connection of multiple SiPMs to increase the ...

Development of the First Tritiated Tetrazine: Facilitating Tritiation of Proteins
ChemBioChem, Volume 23, Issue 23, December 5, 2022., 2022 A tritiated tetrazine based on a phenyl/pyridyl core structure was successfully radiolabeled with NaBT4 by reducing an aldehyde moiety. The synthon was effectively employed to label an antibody in vitro with pretargeted autoradiography. Abstract Tetrazine (Tz)–trans‐cyclooctene (TCO) ligation is an ultra‐fast and highly selective reaction and it is ...

The Muon System of the Run II D0 Detector [PDF]
Nucl.Instrum.Meth.A552:372-398,2005, 2005 We describe the design, construction and performance of the upgraded DO muon system for Run II of the Fermilab Tevatron collider. Significant improvements have been made to the major subsystems of the DO muon detector: trigger scintillation counters, tracking detectors, and electronics.

Electron beam studies of light collection in a scintillating counter with embedded fibers [PDF]
, 2021 The light collection of several fiber configurations embedded in a box-shaped plastic scintillating counter was studied by scanning with minimum ionizing electrons. The light was read out by silicon photomultipliers at both ends. The light yield produced by the 855-MeV beam of the Mainz Microtron showed a strong dependence on the transverse distance ...
