Dr Siriyaporn Sangaroon (Department of Physics, Mahasarakham University, Mahasarakham, Thailand)08/06/2016, 11:00Nuclear and Radiation PhysicsOral presentaionThe tritium is considered as one of main fuels for D-T nuclear fusion reactors, where it is planned to be produced from a blanket of reactors by using the interactions between 14.1 MeV neutrons from nuclear fusion reactions and lithium from the blankets. In this work, the simulations of the tritium production from mock-up breeding blanket due to interactions of neutrons and lithium in the...Go to contribution page

Ms Kanokwan Boonsook (King Mongkut's University of Technology Thonburi (KMUTT))08/06/2016, 11:30Nuclear and Radiation PhysicsOral presentaionThe aim of this study is to analyze the interaction of gamma radiation with powder and bulk hydroxyapatite synthesized from quail eggshell at various doses for development hydroxyapatite as a routine dosimeter. The powder and bulk of hydroxyapatite were irradiated with gamma from 0.1 kGy to 10 kGy. Electron spin resonance (ESR) spectroscopy was used to determine and evaluate dose response from...Go to contribution page

In this paper, we propose an optical surface measurement based on laser scattering to monitor situ the laser cleaning threshold for the removal of graffiti. This technique is meant to assist the laser removal process using laser pulses of 10 ns at 1064 nm while probing the weak laser beam at 632 nm. The diagnostic apparatus consists of a HeNe laser performing a probing light source and...

This paper presents a development of an optical arrangement that captures photons traveling in the multi-pass fashion based on a so-called laser recirculation. An optical trapping scheme is relied on the principle of nonlinear frequency conversion. In this demonstration, a L-shape resonator performing as the master cavity provides a laser beam with a fundamental frequency to create the...

Abstract
Herein we demonstrate the surface plasmon resonance (SPR) refractometers based on smart phone platforms. The optical element used in this system is a single disposable device, which is configures to use conditioned illumination and optical detection from smart phone cameras. The SPR sensing element is fabricated by a soda lime glass slide coated with 50 nm gold film covered by...
