Opis:
In addition to PWO and CsI(Tl) crystals, cerium doped LYSO crystal is considered for the electromagnetic calorimeter part of the Turkish Accelerator Center Particle Factory (TAC-PF) detector, because of its high light yield, fast decay time and good radiation hardness. In this work, LYSO crystals arranged in 3× 3 and 5× 5 matrices have been simulated against photons in the energy range between 50 MeV and 2 GeV, using Geant4 simulation code. Energy resolutions have been estimated considering the contribution of photoelectron statistics coming from the avalanche and PIN photodiodes.

Opis:
PbWO₄ crystal-Hamamatsu S8148 avalanche photodiode (APD) assembly has been used in the barrel section of the CMS electromagnetic calorimeter. The shot noise of the photodiode is one of the important parameters for the energy resolution of the crystal-APD system. The major source of this noise is the statistical variations in the rate at which primary charge carriers are generated and recombine. Thus, the shot noise varies with position of the primary charge carriers generated in photodiode. In this work, the shot noise properties of the Hamamatsu S8148 APD structure and zinc sulfide-silicon (ZnS-Si) isotype heterojunction APD structure have been compared for the PbWO₄ photons. Calculations were made with a Single Particle Monte Carlo simulation technique.

Opis:
The proposed particle factory detector for Turkish Accelerator Center (TAC-PF) being a regional facility in Turkey will operate at the center of mass energy about 3.77 GeV with designed luminosity of the order of 10³⁴ cm¯² s¯¹. The electromagnetic calorimeter part of the detector is considered to have PbWO₄ and CsI(Tl) crystals coupled with photodiodes. In this study, the exposed dose rate to electromagnetic calorimeter during PF detector operation was estimated by FLUKA Monte Carlo tool. The irradiation effects such as the change of light yield and light transmission of these crystals were investigated to evaluate TAC-PF electromagnetic calorimeter energy resolution.

Opis:
There is an intense competition across many sectors in the maritime industry. Coaster owners being in a market where perfect competition rules apply has to be competitive in order to survive. This study aims to analyze the competitiveness of Turkish coaster merchant fleet that consists of the vessels whose cargo carrying capacity differs from 1.000 dwt to 12.000 dwt and that carries dry bulk goods and general cargo based on short sea shipping concept covering Black Sea, Mediterranean and Continental Europe. Based on a qualitative research methodology, interviews were held and data were collected by using semi-structured questionnaire, and the data collected from the interviews was categorized in order to describe and explain patterns and themes. The findings of the interviews were analyzed within the context of sector-specific external factors and company-specific internal factors, and the competitiveness of shipowners operating in the Turkish coaster market was analyzed in detail. It is expected that the findings and implications will especially shed light on the decision makers and policy makers in the sector and contribute to the current literature.
