Abstract AR
تم استقصاء حسابي للخواص الحقيقية و البؤرية الزومية للعدسات الكهروستاتيكية الخماسية الأقطاب الاسطوانية و باستخدام إحدى برامج المحاكاة و المعروف باسم .(LENSYS) و الذي يستخدم طريقة الفروقات المتناهية.
درست النتائج كدالة للفولتية المسيطرة، و قد وجد بأن هذه العدسة بالإمكان تشغيلها بكافة خواصها البؤرية في نمط معين لأجل السيطرة و تبؤر الحزم المشحونة و المستخدمة في الدراسات العملية.
Abstract EN
In the present work, a computational investigation has been considered on the true and a focal zoom-lens (i.e.
lenses whose magnification may be changed without losing focus) for the five-cylindrical electrostatic lens system, by the aid of the simulation program LENSYS, using the finite difference method .Results are obtained as a function of the ratio of the controlling voltages.
It was found that the five-cylindrical lens can be operated with the whole focus properties in a useful mode for controlling and focusing the charged particles in experimental studies.
