DETERMINATION OF OZONE CONCENTRATION AND ITS EFFECT ON DEGRADATION OF MATERIALS

open access: yesTransactions of the VŠB: Technical University of Ostrava, Safety Engineering Series, 2022
The ongoing Covid-19 pandemics showed the need for the effective decontamination of environment and surfaces. One of the options could be the use of gas ozone.

The PADME Detector [PDF]

open access: yesEPJ Web of Conferences, 2018
The PADME experiment, by using the positron beam of the Frascati laboratory, aims at searching for signals of a dark photon, A′ . It will evaluate the final state missing mass of the process e+ e- → A′ γ by knowing the beam energy and measuring the four-momentum of the ordinary recoil photon.

Accelerators and detectors [PDF]

open access: yesReviews of Modern Physics, 1999
The developing understanding of particle physics, especially in the past 60 or so years, has been largely paced by the evolution of high-energy accelerators and detectors. We restrict ourselves here to describing crucial developments in accelerators related to high-energy particle collisions.

Probing the potential of CdZnTe for high-energy high-flux 2D X-ray detection using the XIDer incremental digital integrating readout

open access: yesFrontiers in Physics
The latest synchrotron radiation sources have the capability to produce X-ray beams with a photon flux that can be up to three orders of magnitude higher than previous-generation facilities, and that are not manageable by the currently available 2D ...

First Principles Simulations of Phenol and Methanol Detector Based on Pristine Graphene Nanosheet and Armchair Graphene Nanoribbons

open access: yesSensors, 2019
Over the last decade graphene based electronic devices have attracted the interest of researchers due to their exceptional chemical, electrical and optical properties. Graphene is very sensitive to any physical changes in its surrounding environment and,

Night-Time Detection of Subpixel Emitters with VIIRS Mid-Wave Infrared Bands M12–M13

open access: yesRemote Sensing, 2023
In this paper, we present a new approach to subpixel infrared (IR) emitter detection in VIIRS mid-wave (MWIR) infrared bands M12–M13 at night, based on the presence of a tightly clustered background diagonal present in full granule scattergrams of M12 ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

THE ANTARES DETECTOR

open access: yesInternational Journal of Modern Physics A, 2005
ANTARES is a neutrino telescope under construction in the Mediterranean Sea at the depth of 2500 m, about 40 km off the French coast. A short review of its design and expected performances is presented as well as the status of the project.

Small spacecraft for the registration of micrometeorites and space debris

open access: yesВестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2016
Small spacecraft (SSC) is exposed to fluxes of micrometeoroids and space debris during its flight in space environment. These effects may result in the destruction of the SSC.
