Electron-muon ranger: performance in the MICE muon beam [PDF]

open access: yesJournal of Instrumentation, 2015
The Muon Ionization Cooling Experiment (MICE) will perform a detailed study of ionization cooling to evaluate the feasibility of the technique. To carry out this program, MICE requires an efficient particle-identification (PID) system to identify muons.

Creating Collections with Embedded Documents for Document Databases Taking into Account the Queries

open access: yesComputation, 2020
In this article, we describe a new formalized method for constructing the NoSQL document database of MongoDB, taking into account the structure of queries planned for execution to the database. The method is based on set theory.

Characterisation of the muon beams for the Muon Ionisation Cooling Experiment [PDF]

open access: yesThe European Physical Journal C, 2013
A novel single-particle technique to measure emittance has been developed and used to characterise seventeen different muon beams for the Muon Ionisation Cooling Experiment (MICE). The muon beams, whose mean momenta vary from 171 to 281 MeV/c, have emittances of approximately 1.5--2.3 πmm-rad horizontally and 0.6--1.0 πmm-rad vertically, a horizontal ...

Aggregation of Modified Glucuronoxylan in Water and DMSO. [PDF]

open access: yesBiopolymers
Neutron scattering study of dispersibility of glucuronoxylan and modified glucuronoxylan, in water and dimethyl sulfoxide (DMSO). ABSTRACT Glucuronoxylans are known to be only partly soluble in aqueous media. Chemical modification often aims to improve solubility, yet observations of aggregation even of the modified xylans are not uncommon.

Muon-Muon and Other High Energy Colliders [PDF]

open access: yes, 1997
Parameters are given of 4 TeV and 0.5 TeV (c-of-m) high luminosity muon-muon Colliders. We discuss the various systems, starting from the proton accelerator needed to generate the muons and proceeding through muon cooling, acceleartion and storage in a collider ring. Detector background, polarization are analyzed.

The Enigma of the Muon and Tau Solved by Emergent Quantum Mechanics?

open access: yesApplied Sciences, 2019
This paper addresses the long-standing question of how it may be explained that the three charged leptons (the electron, muon and tau particle) have different masses, despite their conformity in other respects.

Quasi Elastic Neutron Scattering model library [PDF]

open access: yesEPJ Web of Conferences, 2023
This paper reports on the development of a collection of dynamical models of one-dimensional peak profile functions used to fit dynamic structure factors S (Q, ħω) of Quasi Elastic Neutron Scattering (QENS) data.

From [NHC─H]• to Persistent σ‐Complex Radicals: Photoinduced Radical Chemistry of Imidazolium Salts

open access: yesAngewandte Chemie, Volume 138, Issue 24, 8 June 2026.
Visible‐light excitation of electron donor–acceptor (EDA) complexes between imidazolium salts and triarylamines enables controlled single‐electron transfer (SET) and reveals a family of carbene‐centered σ‐complex radical cations. Cryogenic electron paramagnetic resonance (EPR) captures the elusive [NHC─H]• intermediate and its thermal evolution into ...

Estimation of the number of muons with muon counters [PDF]

open access: yesAstroparticle Physics, 2021
The origin and nature of the cosmic rays is still uncertain. However, a big progress has been achieved in recent years due to the good quality data provided by current and recent cosmic-rays observatories. The cosmic ray flux decreases very fast with energy in such a way that for energies $\gtrsim 10^{15}$ eV, the study of these very energetic ...
