E fa'aaoga e le spectrometer se faiga e faitau ai mea e tutupu, ma fa'aogaina le tele-auala fa'atekinolosi e maua ma teu ai le malosi (amplitude) ma fa'amatalaga taimi o le HPGe detector output signal.

 

Fa'atonuga faiga:

O le RJ46 Gamma Spectrometry Systems e fa'atatau i le tele o vaega e tolu: fa'amama sili germanium detector, tele-channel signal processor, ma le potu ta'ita'i. O le fa'asologa o mea fa'apipi'i e aofia ai le HPGe fa'amaufa'ailoga autu, numera tele-channel pulse processor, ma le maualalo le pisa maualuga ma maualalo le eletise eletise; O le polokalama faakomepiuta talimalo e tele lava ina aofia ai le fa'atulagaina o parakalafa, vaega vaega o mea e tutupu mai fa'amatalaga o le mauaina o fa'amatalaga, fua fa'atatau/tete'e-fa'atasi, ma le fa'aaliga o laina alaleo.

 

Vaega:

① Lagolago fuala'au lua fua ole alaleo malosi ma alaleo taimi

② E mafai ona faʻafeiloaʻi faʻamatalaga e ala ile Ethernet ma le USB

③ Fa'atasi ai ma polokalama fa'akomepiuta fa'atatau lelei

④ Taimi maualuga ma le maualuga o le malosi, lagolago maualuga

⑤ Fa'afuainumera fa'amama fa'afuainumera, to'esea fa'amau fa'avae

⑥ E mafai ona maua faʻamatalaga faʻapitoa ma faʻamatalaga o alaleo malosi e tuʻuina atu e le masini ma faʻasaoina e avea o se faʻamaumauga
