Abstract

ABSTRACT
This paper describes depth dose measurement of Low Energy Electron Accelerator (LEEA). This locally designed LEEA with the former energy of 140 keV will be upgraded to 300 keV. As the setup, the electron beam is energized by the electric field with the high voltage power supply, scanning and passing through the titanium foil to irradiate the sample. As the results, depth dose profile by the energetic beam mapping results have been obtained by using B3 radio chromic film and FWT-60 nylon dosimeters.

ABSTRAK
Kertas kajian ini menerangkan pengukuran dos kedalaman Pemecut Elektron Tenaga Rendah (LEEA). LEEA reka bentuk tempatan dengan tenaga 140 keV dahulu akan dinaik taraf kepada 300 keV. Sebagai persediaan, pancaran elektron ditenagakan oleh medan elektrik dengan bekalan kuasa voltan tinggi, mengimbas dan melalui kerajang titanium untuk menyinari sampel. Hasilnya, profil dos kedalaman oleh hasil pemetaan rasuk bertenaga telah diperoleh dengan menggunakan filem kromik radio B3 dan dosimeter nilon FWT-60.
