10. Efekty studené jaderné hmoty

Jaroslav Štorek (CTU FNSPE)

16/01/2018, 09:00

V příspěvku budou po krátkém úvodu standardního modelu vysvětleny všechny základní pojmy fyziky vysokých energií. Dále bude uvedena QGP a efekty stínění. Podrobněji budou rozebrány efekty produkce těžkých kvarků, především studené jaderné hmoty. Na závěr příspěvku budou shrnuty dosavadní výsledky na experimentech STAR, CMS a ALICE.

1. Simulation of semiconductor pixel detector response

Matěj Vaculčiak (CTU FNSPE)

16/01/2018, 09:15

In my thesis, I go in for a detector optimisation using mainly the Geant4 toolkit and Allpix-squared, a new Geant4-based program which is currently being developed in collaboration with CERN facility. In particular, I focus on radiation resistible semiconductor monolithic pixel detectors used in space dosimetry.

3. Dose distributions of different particles in a water phantom

Tadeáš Kmenta

16/01/2018, 09:30

Monte Carlo simulation using FLUKA code for dose distribution is presented and discussed. Dose distribution was scored in water phantom block produced by photon, electron, proton and carbon ion pencil beams for various energies using 1 million primary particles for 5 cycles. A comparison and analysis of particles contributing to the total dose deposited is given as well as the dose shapes.

35. Efekty horké a studené jaderné hmoty ve srážkových experimentech

Jakub Kubát (ČVUT FJFI)

16/01/2018, 09:45

Na urychlovačích LHC v ženevském CERNu a RHIC v americké BNL jsme dnes schopni dosahovat energií, které nám umožňují simulovat podmínky na úplném počátku vesmíru. V jádro-jaderných srážkách zkoumáme fázi hmoty, ve které se barevně nabité kvarky a gluony pohybují v nevázaných stavech. Toto extrémně horké médium nazýváme kvark-gluonové plazma (QGP) a pomocí četných experimentálních metod...

11. Study of the QGP medium with heavy quarkonia

Martin Klíštinec (CTU FNSPE)

16/01/2018, 10:15

In this thesis i am focusing on measuring the propheties of quark-gluon plasma via suppresion of mezon $\Upsilon$. This thesis also contains information about basic propheties of quark-gluon plasma and efects that cause suppresion or enhancement of mezon $\Upsilon$.

17. Characterization of semiconductor detectors for space environment

Anežka Kabátová (CTU FNSPE)

16/01/2018, 10:30

The subject of my thesis is space radiation detection using semiconductor detectors.
Firstly, simulation of detector response in Geant4 - Monte Carlo based software toolkit is involved. Later, test measurement is carried out on Tandetron accelerator in Řež.

31. Optimalizace rekonstrukce půvabných hadronů v srážkách d/p+Au

Tomáš Truhlář (CTU FNSPE)

16/01/2018, 10:45

The subject of my thesis is optimalization of charm hadrons reconstruction especially in d/p+Au collisions using multivariate data analysis.
The first part of my talk is about the The Toolkit for Multivariate Data Analysis with ROOT (TMVA) itself. Then its importance is demonstrated on some examples in HEP. And in the end, results gained by using TMVA are compared with results from classical analysis.

40. Coherent $\rho^0$ photoproduction in heavy ion collisions

Gitika Bhalla (CTU FNSPE)

16/01/2018, 11:15

A summary of several papers on the coherent $\rho^0$ photoproduction in ultra-peripheral heavy ion collisions and the comparison of their findings along with model comparisons. 4 papers by the STAR collaboration reporting on Au-Au collisions at $\sqrt{S_{NN}}=130$ GeV, $\sqrt{S_{NN}}=200$ GeV, $\sqrt{S_{NN}}=62.4$ GeV, and one by the ALICE collaboration reporting on Pb-Pb collisions at...

28. Laser wakefield acceleration of electrons.

Ekaterina Eremenko (CTU FNSPE)

16/01/2018, 11:30

Laser based acceleration technology allows to produce high electric fields with a centimeter-scale device. The basic physics of Laser Wakefield Acceleration is introduced. To get stable mono-energetic electron beam, particles should be firstly injected into the plasma wave. Different types of electron injection are reviewed. The experimental techniques for density measurement above the...

15. Experimental study of coincidence processes in microscopic quantum hardware generators of coincidence events

Mr Tomáš Novák (Bachelor student)

16/01/2018, 11:45

Presenting microscopic quantum hardware generators of coincidence events. Generators evenly gathering data sets of measured coincident quantum based variable. Evolution of such variable is examined by the tools of the TISEAN software package exploiting the approach of non-linear times series analysis.
