Elementary particles and fundamental forces: problems and perspectives

David Karakhanyan

The subject of this lecture is X-Ray Fluorescence (XRF) analysis, which is widely used for elemental analysis of inorganic materials. It provides one of the simplest, most accurate and most economic analytical methods for the determination of the chemical composition of many types of materials. The XRF is the emission of characteristic (or fluorescent) X-rays from a material that has been excited with X-rays. Analysis of XRF spectra allows determining the chemical composition of the material. The purpose of the lecture is to give some basic information about X-ray Fluorescence analysis, including XRF theory and instrumentation. The lecture covers the following topics

Brief history of discoveries in the field of X-rays Basics of XRF theory Evaluation of XRF spectra XRF instrumentation Analysis software

The lecture is an introduction to the master course to be started at Yerevan Physics institute in October. The course contains the basic facts of the modern theoretical high-energy physics. The main topics of lecture are: the micro- and macro-scale Universe, the elementary particles and the fundamental interactions between them. The course will contain an introduction to Standard Model, Quantum chromodynamics, quantum gravity and cosmology.

Particle detectors are an interface from micro to macro world. They make visible to us tiny elementary particles. By using different experimental techniques we can count particles, measure their energy, determine their types. All physics, new models and theories contained in huge amount of electric signals entering online computers at rate of tens of kilohertz in cosmic ray experiments till gigahertz in collider experiments. During lab works based on modern particle spectrometers and high-speed electronics various particle registering and their energy estimation tasks will be explained and demonstrated.

Particle detectors and how to treat signals from them (nuclear electronics)

Ara Daryan and Gagik Hovsepyan

Uncertainty relations (and the ensuing notions of complementarity and contextuality) are basic for quantum mechanics; this is the main place, where quantum mechanics differs from classical theories. Over the decades that followed the emergence of quantum mechanics, the man understanding of uncertainty relations was based on heuristics of Heisenberg-Robertson-Schroedinger inequalities, which do not manifestly refer to simultaneous measurements of non-commuting quantities. This state of affairs was rightly criticized for many years, but only very recently a series of new uncertainty relations were developed that improve our understanding of the most counter-intuitive aspect of quantum mechanics.

The lecture is an introduction to the master course to be started at Yerevan Physics institute in October 2014. It is designed to introduce the experimental techniques and the data analysis methods of Particle Astrophysics. We will review particle physics and particle detectors to remind or introduce basic concepts that will be used throughout the course. We will present the characteristics of energy losses of radiation with matter that are important for their detection. Examples of existing experiments will be provided for following fields of astroparticle physics: detection of the secondary cosmic rays, gamma and neutrino astronomy and cosmology. Students will be introduced to data analysis methods through practical examples. The course will include practical applications involving data analysis of data flow from the facilities of the Aragats space Environmental Center (ASEC).

Simulation of physical processes with Geant4 code

LevonVanyan

Geant4 (for GEometry ANd Tracking) is a platform for "the simulation of the passage of particles through matter ," using Monte Carlo methods. It is the successor of the GEANT series of software toolkits developed by CERN and the first yo use object oriented programming ( in C++).Itsdevelopment, maintenance and user support are taken care by the international Geant4 Collaboration.Application areas include high-energy physics and nuclear experiments, medical,accelerator and space physics studies. The software is used by a number of research projects around the world. The Geant4 software and source code is freely available from the project web site. The lecture is a brief introduction to both GEANT4

package and Monte Carlo method.

ADEI (Advanced Data Extraction Infrastructure) is dynamic web interface for browsing, analysis and extraction of time-series from various data sources. During this course students will learn how to use ADEI to analyze multivariate data.

Multivariate Data analysis with ADEI platform

Arthur Reymers

Mathematical statistics recovers data from incomplete (noisy) measurements, while physical statistics develops a probabilistic description for physical systems that either interact with uncertain environment or are too complex to be described deterministically. These two disciplines normally develop independently: mathematical statistics is employed in experimental physics research, while physical statistics refers to specific branches of physics (statistical mechanics, kinetics, etc). However, it appears that a direct link can be established between them in the context of the maximum likelihood method (or its generalizations such as the maximum a-posteriori method). Here, the data recovery for a partially observed random Markov process is mapped to the physical statistics of one-dimensional Ising model. This map enriches the understanding of both disciplines and allows employing methods and ideas of statistical physics for mathematical statistics.

Introductory lecture will describe facilities and services of YerPhI

· High-Performance Computing service;

· YerPhI Batch Cluster System;

· Grid Computing at YerPhI;

· YerPhI Network Overview;

· Eduroam and videoconferencing services

· Local Cisco Networking Academy Training Centre

During Laboratory work an introduction to Linux operation system will be made.The evolution of Linux and other popular operating systems Win, MacOS, Android will be explained. We will also discuss the considerations for choosing of an operating system. By performing this lab, students will learn how to navigate and manage Linux System files and directories.

The lecture is devoted to the issues of research and production of the widely used in medicine radioactive isotopes. The worldwide experiences in obtaining short leaving isotopes and their usage for diagnostic purposes are briefly introduced. The experimental program undergoing at Yerevan Physics Institute is discussed, including the pilot project of

99mproduction of one of the most important in diagnostic Tc isotope with 18 MeV proton beam from installing on premises of YerPhI IBA C-18 cyclotron.

99mDuring lab work the Tc radiological purity measurements will be

99mperformed. The Tc “drug” used in the clinics represents a pertechnetate

99m - 99m( TcO ) dissolved in saline. Also there is a small quantity of Tc in atomic 4

state (also radioactive) in that solution which doesn't participate in the metabolism and therefore is useless and its consistent is strongly limited.

99m 99m - 99mThe radiological purity is the ratio of ( Tc) / ( TcO + Tc) activities in 4

the solution and it must be less than 5%. The method which will used to measure the radiological purity is called thin layer chromatography.
