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 WebNov 1, 2003 · The avalanche photodiode (APD) is a high-performance and compact light sensor recently applied in various fields of experimental physics. 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
