Test of a Fiber Optic Scintillation Dosimeter with BGO Tip in a Co Irradiation Chamber
Following a previous feasibility study, a photon dosimeter have been constructed by attaching a small piece of BGO scintillator to a low attenuation plastic optical fiber for which the light output is measured with a current-type PMT. The dosimeter model is tested in a Co irradiation chamber in the dose rate range varying from about 50 to 1200 Gy/h. The dose rates are measured at a number of pr...
متن کاملA Scintillating Fiber-optic Dosimeter for Co-60 Radiotherapy
In this study, we have fabricated a scintillating fiberoptic dosimeter (SFOD) for a Co-60 radiotherapy dosimetry. The γrays generated from a Co-60 machine are measured using a SFOD and percent depth dose (PDD) curves are obtained according to the different depths of water phantom. Also, Cerenkov lights generated by the interactions of primary or secondary electrons and a plastic optical fiber a...
متن کاملA fiber optic sensor for measuring glucose in aqueous solutions
In this paper, the set-up of a multi-mode fiber optic sensor for measuring glucose in aqueous solutions is investigated and evaluated. The basis of this sensor is based on the Fresnel Reflection. In this setup, a helium-neon laser is used as a light source, a fiber optic probe, photocell as detector and a digital multimeter. The statistical analysis of the recorded data shows a highly linear be...
متن کاملAbsolute interferometric test of cylindrical wavefront with a fiber optic
A method of absolute testing of a cylindrical wavefront is presented. The method is a merging of the random ball test method with the fiber optic reference test. The random ball test assumes a large number of interferograms of a good quality sphere with errors that are statistically distributed such that the average of the errors goes to zero. The fiber optic reference test utilizes a specially...
متن کاملa swot analysis of the english program of a bilingual school in iran
با توجه به جایگاه زبان انگلیسی به عنوان زبانی بین المللی و با در نظر گرفتن این واقعیت که دولت ها و مسئولان آموزش و پرورش در سراسر جهان در حال حاضر احساس نیاز به ایجاد موقعیتی برای کودکان جهت یاد گیری زبان انگلیسی درسنین پایین در مدارس دو زبانه می کنند، تحقیق حاضر با استفاده از مدل swot (قوت ها، ضعف ها، فرصتها و تهدیدها) سعی در ارزیابی مدرسه ای دو زبانه در ایران را دارد. جهت انجام این تحقیق در م...
