Diamond detectors for the TOTEM timing upgrade

G. Antchev, P. Aspell, Ivan Atanassov, V. Avati et autres

This paper describes the design and the performance of the timing detector developed by the TOTEM Collaboration for the Roman Pots (RPs) to measure the Time-Of-Flight (TOF) of the protons produced in central diffractive interactions at the LHC . The measurement of …

Measurement of elastic pp scattering at $$\sqrt{\hbox {s}} = \hbox {8}$$ s = 8 TeV in the Coulomb–nuclear interference region: determination of the $$\mathbf {\rho }$$ ρ -parameter and the total cross-section

G. Antchev, P. Aspell, I. Atanassov, V. Avati et autres

The TOTEM experiment at the CERN LHC has measured elastic proton–proton scattering at the centre-of-mass energy $$\sqrt{s}=8\,$$ TeV and four-momentum transfers squared, |t|, from $$6\times 10^{-4}$$ to 0.2 GeV $$^{2}$$ . Near the lower end of the t-interval the differential cross-section is …

Modeling and validation of ΣΔ modulators

Lukas Palocko

The article is focused on modeling and validation of Sigma-Delta Modulator (ΣΔM). The levels of abstraction - including behavioral, circuit-level and physical modeling of analog integrated circuits - are discussed. A behavioral modeling is presented and macromodels of ΣΔM cells are introduced. …

Evidence for non-exponential elastic proton–proton differential cross-section at low |t| and s=8TeV by TOTEM

G. Antchev, P. Aspell, Ivan Atanassov, Valentina Avati et autres

The TOTEM experiment has made a precise measurement of the elastic proton–proton differential cross-section at the centre-of-mass energy s = 8 TeV based on a high-statistics data sample obtained with the ⁎ β ⁎ = 90 m optics . Both the statistical …

Principle of Power Factor Corrector with Critical Conduction Mode

Jan Moldaschl, Jan Broulím, Lukas Palocko

In recent years, interest in the application of the Power Factor Corrector has grown considerably. This paper gives a comprehensive account of Critical Conduction Mode (CrM) in the Power Factor Corrector. The Critical Conduction Mode technique is newer than Continuous Conduction Mode …

Boost power factor correction topology with average current control

Jan Moldaschl, Jan Broulím, Lukas Palocko

This paper presents experimental results of a power factor corrector (PFC) with the average current control. Nowadays, we need a power factor corrector for most switch mode power supplies. Usually, a boost corrector with the average current control is used. The average …

LDPC code optimization based on Tanner graph mutations

Jan Broulím, Vjačeslav Georgiev, Jan Moldaschl, Lukas Palocko

The paper presents LDPC error correcting code optimization based on Tanner graph mutations. A statistical experiment focused on a heuristic LDPC code construction was performed with the genetic algorithm. The algorithm used is briefly described. Short wordlength LDPC code optimization was simulated. …
