A network of Timepix (TPX) devices installed in the ATLAS cavern measures LHC luminosity as a function time stand-alone system. The data were recorded from 13 TeV proton-proton collisions 2015. Using two TPX devices, number hits created by particles passing pixel matrices was counted. van der Meer scan beams analysed using bunch-integrated averages over different bunch profiles for an approximate absolute normalization. It is demonstrated that has capability to measure reduction with...
A network of Timepix (TPX) devices installed in the ATLAS cavern measures Large Hadron Collider (LHC) luminosity as a stand-alone system. The data were recorded from 13-TeV proton–proton collisions 2016. Using two TPX devices, number hits created by particles passing pixel matrices was counted. Absolute is determined with van der Meer scan technique separating LHC proton beams and measuring widths low-intensity collisions. exact determination activation background contributes to overall...
This paper presents an automatic approach for optimal calibration of the deceived non local means filter (DNLM), enhancing segmentation accuracy fluorescence based microscopy images. The DNLM is designed image denoising and enhancement. its parameters in real preprocessing applications very often time consuming, since doing a manual sample might not work different samples. We compared three stochastic optimization approaches: simulated annealing, particle swarm genetic algorithms, selected...
A network of Timepix (TPX) devices installed in the ATLAS cavern has unique capability measuring luminosity with thermal neutron counting Large Hadron Collider proton-proton collisions at 13 TeV. Compared hit-counting method, method advantage that it is not affected by induced radioactivity. The results determination are presented for several independently operated TPX detectors. long-term time stability measurements individual and between different devices. high-statistics data sets allow a...

A network of 15 Timepix pixel detectors was installed within the ATLAS experiment at CERN, Geneva. The is capable measuring composition and spectral characteristics radiation fields in real-time. Its operation managed by a dedicated software system. presented article describes primary components this system responsible for communication with detector hardware, online monitoring, remote acquisition control, automated data verification analysis. processed can be accessed through an interactive...
