The fraction of delayed neutrons in a moderated beam from the enriched uranium, pulsed spallation source at the intense pulsed neutron source at Argonne National Laboratory has been measured and found to be 0.0283 for 450-MeV protons. Delayed neutrons produce a sample-dependent background in time-of-flight instruments . Because of the distribution of neutron wavelengths in the prompt pulse, the...
Different lasers and intense pulsed light (IPL) sources have been used over the last years to achieve reduction of facial telangiectasias. Multiple studies have shown IPL to be effective using subjective assessment of results, and one study has also shown long-term effects as judged by photos and patient self-assessment.. For the purpose of getting an objectice evaluation of the effect of IPL o...
The recent development of the intense pulsed muon source at J-PARC MUSE, Japan Proton Accelerator Research Complex/MUon Science Establishment (10(6) s(-1) for a momentum of 60 MeV/c), enabled us to pioneer a new frontier in analytical sciences. Here, we report a non-destructive elemental analysis using µ(-) capture. Controlling muon momentum from 32.5 to 57.5 MeV/c, we successfully demonstrate ...
Restoration of form and function after burn injury remains challenging, but emerging laser and pulsed light technologies now offer hope for patients with hypertrophic scars, which may be associated with persistent hyperemia, chronic folliculitis, intense pruritis, and neuropathic pain. In addition to impairing body image, these scars may limit functional recovery, compromise activities of daily...
در این پایان نامه به بررسی کمی یک سیستم تصویربرداری پراش افزوده(diffraction enhanced imaging-dei) پرداخته ایم. بدین منظور مشخصات توان و شار و نحوه توزیع پرتوهای سینکروترون مورد بررسی قرار داده و سپس محاسبات پرتو خط بیم(national synchrotron light source) nsls شامل رزولوشن انرژی و شار رسیده به نمونه را انجام دادیم و در نهایت با ارائه یک مدل برای سیستم dei میزان بهبود کنتراست تصویر در این سیستم نس...
