Abstract

Telah dilakukan penelitian untuk membandingkan kinerja dua buah modul elektronik yaitu modal ORTEC dan modal NC-26R yang masing-masing merupakan bagian dan sistern Anti Compton. Pembandingan kinerja kedua modal tersebut dilakukan pada pemiliha.n sinyal yang hams ditolak. Pernilihan sinyal ini dilakukan dengan metode waktu tunda menggunakan somber Cs137. Setelah pengaturan dilakukan maka untuk modul. ORTEC diperoleh hasil TTCF NaI(TI) = 111,6 ns ; TARc HpGe = 42,5 ns dan faktor supressi (SF) untuk daerah backscatter 2,23; daerah valley 4,26; daerah edge 5,92 dan pada puncak 1,03. Untuk modul NC-26R TARc Ne(Tl) = 12 us ; TAK HpGe = 45,3 ns dan faktor supressi (SF) untuk daerah backscatter 2,30 ; daerah valley 3,67 ; daerah edge 4,45 dan pada puncak 1,25; sehingga modul ORTEC mengliasilkan faktor supressi yang lebih balk nada daerah edge, daerah valley dan pada puncak. A research has been done to compare the performance of two electronic modules, that is ORTEC module and NC-26R module which are part of the Anti Compton system. The comparison of two modules performance was done at the rejected signal selection. The signal selection was done with time delay method using Cs''' source. As the setting has done hence for ORTEC module, the result was obtained that TTCF NaI(TI) = 111,6 ns; T,c HpGe = 42,5 ns and the suppression factor (SF) for backscatter area is 2,23; valley area is 4,26; edge area is 5,92 and peak area is 1,03. For NC-26R module TARc Na1(T1) = 12 ns, TARc HpGe = 45,3 ns and suppression factor (SF) for backscatter area is 2,30; valley area is 3,67; edge area is 4,45 and peak area is 1,25; thus the ORTEC module yields better suppression factor at the edge area, valley area and the peak area.
