National Research Nuclear University, Moscow Engineering Physics Institute, Russia A full-body gamma-camera based on SiPM readout is currently under development as a part of MEPHI R activity supported in the framework of Russian Megagrants program. A goal of this development is a fast upgrade of existing medical equipment with minor changes in a system design and construction in order to combin...

We develop a new discrimination procedure for separating electron neutrinos from muon neutrinos, based on detailed simulations carried out with GEANT 3.21 and with newly derived mean angular distribution functions for the charged particles concerned (muons and electrons/positrons), as well as the corresponding functions for the relative fluctuations. These angular distribution functions are con...

Design and maintenance of nuclear cycle facilities mandatory imply implementation of efficient radiation protection. Radiation environment assessment and shielding optimization require a considerable amount of numerical calculations. Nowadays mathematical modelling methods and corresponding software are widely used for such kind of problems. All the software used for radiation fields modelling ...

Title of dissertation: ELLIPTIC FLOW AT FORWARD RAPIDITY IN √ sNN = 200 GeV Au+Au COLLISIONS Eric Michael Richardson, Doctor of Philosophy, 2012 Dissertation directed by: Professor Alice C. Mignerey Department of Chemistry and Biochemistry Forward rapidity elliptic flow (v2) of both unidentified charged hadrons and decay muons has been measured from √ sNN = 200 GeV Au+Au collisions as a functio...

The recent results from the HEIDELBERG–MOSCOW experiment have demonstrated the large potential of double beta decay to search for new physics beyond the Standard Model. To increase by a major step the present sensitivity for double beta decay and dark matter search much bigger source strengths and much lower backgrounds are needed than used in experiments under operation at present or under con...

NORDUNET began as an informal cooperation between Nordic “networkers” in 1980. With support from the Nordic Council of Ministers, a NORDUNET project for a common Nordic academic network began in 1985. Mats Brunell (Sweden) and Einar Løvdal (Norway) led the work. Originally based on existing interim services of EARN, DECnet and ISO OSI support, lack of services led to complete reorientation in 1...

The purposes of this study were to optimize a proton computed tomography system (pCT) for proton range verification and to confirm the pCT image reconstruction algorithm based on projection images generated with optimized parameters. For this purpose, we developed a new pCT scanner using the Geometry and Tracking (GEANT) 4.9.6 simulation toolkit. GEANT4 simulations were performed to optimize th...

As Internet traffic continues to grow unabated at an exponential rate, it is unclear whether the existing packet-routing network architecture based on electronic routers will continue to scale at the necessary pace. On the other hand, optical fiber and switching elements have demonstrated an abundance of capacity that appears to be unmatched by electronic routers. In particular, the simplicity ...

Depth distributions of positron-emitting nuclei in PMMA phantoms are calculated within a Monte Carlo model for Heavy-Ion Therapy (MCHIT) based on the GEANT4 toolkit (version 8.0). The calculated total production rates of C, C and O nuclei are compared with experimental data and with corresponding results of the FLUKA and POSGEN codes. The distributions of e annihilation points are obtained by s...
