Control of ambient temperature is particularly critical when one apparatus is stacked above another, because the heat generated from the lower unit can interfere with the operation of the units above.
It combines the high-resolution capability of cryogenically cooled semiconductors, with the ambient-temperature operation capability of scintillators.
它结合了深冷冷却半导体的高清晰度能力，在闪烁常温操作能力。
