Reach through apd
WebNov 21, 2007 · Among several types of APDs, the reach-through APD offers an advantage in direct X-ray detection, thanks to its thick depletion layer ( ⩾ 100 μ m) in front of the amplification region. This type of APD is also sensitive to weak scintillation light from gamma-ray scintillators with a high quantum efficiency of ∼ 80 % (at λ ≃ 500 nm ). WebA reach-through APD of a 130 µm thickness can potentially detect soft X-rays below 20 keV with efficiencies greater than 10%. The signal amplification in the APD devices has a good advantage of detecting soft X-rays even at room temperature or at lightly cooled environment[11,12]. Figure 3 presents
