LBNO-DEMO (WA105): a large demonstrator of the Liquid Argon double phase TPC
2016
LBNO-DEMO (WA105) is a large demonstrator of the double phase liquid argon TPC intended to develop and test the main elements of the GLACIER-based design for the purpose of scaling it up to the 10–50 kton size needed for Long Baseline Neutrino Oscillation studies. The crucial components of the design are: ultra-high argon purity in non-evacuable tank, long drifts, very high drift voltages, large area Micro Pattern Gas Detectors, and cold preamplifiers. The active volume of the demonstrator is 6×6×6 m3 (approximately 300t). WA105 is under construction at CERN and will be exposed to charged particle beams (0.5-20 GeV/c) in the North Area in 2018. The data will provide the necessary calibratio…
Validation of 2D Force Measurement Roller Ski and Practical Application.
2022
Several methods could be used to measure the forces from skis or roller skis in cross-country skiing. Equipment that could measure medio-lateral forces may be of good help for investigating the relevant skating techniques. The aim of this study was to validate a pair of newly designed two-dimensional force measurement roller skis. The vertical and medio-lateral forces which were perpendicular to the body of the roller ski could be measured. Forces were resolved into the global coordinate system and compared with the force components measured by a force plate. A static and dynamic loading situation for the force measurement roller ski was performed to reveal the validity of the system. To de…

Instrumenti sabiedrības ietekmei uz likumdevēju tiesiskā demokrātiskā valstī
2020
Maģistra darba tēma ir „Instrumenti sabiedrības ietekmei uz likumdevēju tiesiskā demokrātiskā valstī”. Lai sabiedrība varētu izveidot valsti, kurā tā gribētu dzīvot, sabiedrībai ir svarīgi apzināties tās iespējas un pieejamos instrumentus likumdevēja ietekmēšanai. Darba mērķis ir noskaidrot, kas ir sabiedrība likumdošanas kontekstā, tās esošos instrumentus un to izpausmes ietekmei uz likumdevēju tiesiskā demokrātiskā valstī, instrumentu efektivitāti un piemērošanas sekas, kā arī uz konkrēta gadījuma piemēra analizēt cik ilgā laikā un kādai sabiedrības grupai izdevās realizēt pastāvošas kārtības maiņu. Darba uzdevumi ir analizēt demokrātiskās valsts iekārtas būtību un tās izpausmi, likumdoša…
Seasonal Modulation of the $^7$Be Solar Neutrino Rate in Borexino
2017
We detected the seasonal modulation of the $^7$Be neutrino interaction rate with the Borexino detector at the Laboratori Nazionali del Gran Sasso in Italy. The period, amplitude, and phase of the observed time evolution of the signal are consistent with its solar origin, and the absence of an annual modulation is rejected at 99.99\% C.L. The data are analyzed using three methods: the sinusoidal fit, the Lomb-Scargle and the Empirical Mode Decomposition techniques, which all yield results in excellent agreement.
L’instrumentum métallique lié à la cuisine en Gaule romaine
2013
The metal finds associated to storage, food and liquids preparation and cooking comprise multipurpose and specific instruments. The first two phases are illustrated by rather few utensils: buckets, barrels, jugs and boilers, knives and other cleavers. Three cooking patterns are used for the third phase. The first one, simmering, needs hinged cauldrons, assembled or in one piece, maintained above the hearth by suspension chains, but also cauldrons and pots (jars) put down on cooking stands. Grilling needs gridirons, firedogs, braziers and roast spits. At last, for quick cooking with the supply of fat or water which allow to sear food pans and cooking stands are mainly being used. Small imple…

Separation of atomic and molecular ions by ion mobility with an RF carpet
2021
Gas-filled stopping cells are used at accelerator laboratories for the thermalization of high-energy radioactive ion beams. Common challenges of many stopping cells are a high molecular background of extracted ions and limitations of extraction efficiency due to space-charge effects. At the FRS Ion Catcher at GSI, a new technique for removal of ionized molecules prior to their extraction out of the stopping cell has been developed. This technique utilizes the RF carpet for the separation of atomic ions from molecular contaminant ions through their difference in ion mobility. Results from the successful implementation and test during an experiment with a 600~MeV/u $^{124}$Xe primary beam are…
