| چکیده | ||
| در مقاله حاضر، به ساخت و مشخصهیابی هدف تیتانیومی بر زیرلایه مس بهمنظور تولید ذرات نوترون در شتابگرالکتروستاتیک ES-150 پرداخته شده است. مس، بهدلیل رسانایی حرارتی بالا و تیتانیوم بهدلیل ضریب جذب بالای هیدروژن بهترتیب بهعنوان زیرلایه و ماده هدف انتخاب شدند. به این منظور لایهنازکی از فلز تیتانیوم با روش کندوپاش پرتو یونی بر زیرلایه مسی انباشت شد. ساختار بلوری تشکیلشده در نمونه‌ها به کمک طیف‌سنجی پراش پرتو ایکس(XRD) ، ریختشناسی سطح به کمک میکروسکوپ الکترونی روبشی(SEM) و توزیع‌وترکیب عناصر موجود در نمونه‌ها نیز با استفاده از طیف‌سنجی پراش انرژی پرتو ایکس (EDX) بررسی شده است. طیف‌سنجی XRD قلّه‌های مختلف تیتانیوم با جهتگیری غالب Ti(002) را در زاویه o42/38 برای لایه رسوب‌شده نشان می‌دهد. تصاویر SEM، لایهای با ساختار یکنواخت با توزیع منظم دانهها و بدون نقص را نشان می‌دهد و نتیجه بررسی EDX نیز شامل عناصر تیتانیوم و مس میباشد. مشخصــهیابی عنصری با روش‌های مبتنی بر آنالیز با باریکه یونی نشان می‌دهد که نمونه دارای یک زیرلایه مسی ضخیم و لایه تیتانیوم با ضخامت µm 19/0 ± 90/1 است. میزان شار نوترونی مربوط به اهداف ساخته‌شده در شتابگر الکتروستاتیک KeV150، مطالعه و بهره نوترونی در راستای محور باریکه اندازهگیری شد. بیشینه بهره نوترونی از مرتبه n/s 107 بدست آمد. | ||

| چکیده [English] | ||
| This article presents the fabrication and characterization of a titanium target deposited on a copper substrate, designed for generating neutron particles in the ES-150 electrostatic accelerator. The selection of copper as the substrate and titanium as the target material was based on their respective properties: copper's exceptional thermal conductivity and titanium's high hydrogen absorption coefficient. A titanium thin film was deposited onto the copper substrate using ion beam sputtering. The resulting crystal structure, surface morphology, and elemental composition of the samples were analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM), and X-ray spectrophotometry (EDX), respectively. X-ray diffraction (XRD) analysis revealed distinct titanium peaks, primarily oriented along the Ti (002) plane at an angle of 38.42o. The scanning electron microscopy (SEM) results indicate a uniform film with a regular grain distribution and no visible defects. Energy Dispersive X-ray analysis (EDX) further confirmed the presence of titanium and copper elements in the target. Ion beam analysis-based elemental characterization revealed a thick copper substrate and a titanium layer, which was 1.90 ± 0.19 µm thick. The neutron flux produced by the targets in the 150 KeV electrostatic accelerator was investigated, and the neutron yield was measured along the beam axis. A maximum neutron yield of 107 n/s was achieved. | ||
