Solaris is a third generation light source constructed at the Jagiellonian University in Krakow, Poland. The machine was designed by the MAX IV Laboratory team. The replica of the 1.5 GeV storage ring with 96 m circumference of a vacuum system was successfully built and now the synchrotron facility is after the 3rd phase of commissioning. Recent installation of the Residual Gas Analyzer (RGA) in t

In order to investigate the possible causes of premature thermal breakdown and performance degradation, several diagnostic techniques have been employed during the vertical tests of the Fine and Large Grain ESS Medium Beta prototypes cavities. The whole equipment, which includes second sound, fast thermometry, photodiode x ray detectors and external NaI scintillator and proportional counter, is he

In this paper we propose to describe the self-force of a particles beam, known as space charge, as a Hamiltonian term dependent on the distribution of the particles' coordinates: Hsc ≡ Hsc(ρ(x, y, z)). This Hamiltonian is then used, together with the kinetic component Hk in a Lie transform to generate a transport map by e-L:Hk+Hsc: where the Lie operator: Hk + Hsc : is defined according to the Dra

The report takes a statistical approach in the study of distribution evolution of the proton beam within the ESS linac and reports a new technique of pinpointing the non-linear space-charge effect of the propagating proton beam. By using the test statistic from the nonparametric Kolmogorov-Smirnov test the author visualises the change in the normalised distributions by looking at the supremum dist

Thin films of cadmium oxide (CdO) with different thicknesses in the range of 78–250 nm were prepared and deposited on glass substrates by using a spray pyrolysis technique. A microbeam facility (Lund Ion Beam Analysis facility) was used to irradiate the prepared CdO thin films with a 1.5 MeV proton beam for fluence in the range of 2 × 1012–2 × 1014 ions/cm2. The surface morphology of the CdO films

Physical exercise affects hippocampal structure and function, but the underlying neural mechanisms and the effects of exercise intensity remain incompletely understood. Therefore, we undertook a comprehensive, multi-modal 3T and 7T MRI randomized controlled trial (Netherlands Trial Register - NL5847) in which we randomized 52 young, non-athletic volunteers to a 12-week low- or high-intensity exerc

Background and aims: Skin autofluorescence (AF), a measure of tissue accumulation of advanced glycation endproducts (AGEs), has been associated with diabetes and cardiovascular disease. However, the association of skinAF with subclinical coronary atherosclerosis in the general population is largely unknown. Our study aimed toexamine the associations between skin AF and subclinical atherosclerosis

Background: Several studies have examined the role of physical activity as a predictor of heart failure (HF) mortality and morbidity. Here, we aimed to evaluate the role of self-reported physical activity as an independent risk factor of post-discharge mortality and re-hospitalization in patients hospitalized for HF, as well as study the association between physical activity and 92 plasma proteinsBackground: Several studies have examined the role of physical activity as a predictor of heart failure (HF) mortality and morbidity.

The analysis of acid-base disturbances contributes to the diagnostic work-up of critically ill patients. Most emergency departments are equipped with blood gas point-of-care analyzers that quantify within minutes pH, pCO2, standard bicarbonate, standard base excess, sodium and chloride levels. This article provides a pragmatic stepwise approach to the analysis of acid-base disturbances in the emer

Quantifying the ways in which local particle rearrangements contribute to macroscopic plasticity is one of the fundamental pursuits of granular mechanics and soft matter physics. Here we examine local rearrangements that occur naturally during the deformation of three samples of 3D granular materials subjected to distinct boundary conditions by employing in situ x-ray measurements of particle-reso
