项目摘要

We have built a test setup to measure the linearity with the precision of 0.1%. By using the system, we have evaluated the linearity of the following new types of photo detectors.*Avalanche type photo diodeA bias voltage of about 1500V-2400V is applied on an avalanche photo diode (APD). A photon entering the p-type silicon forms an electron-hole pair. The electron is accelerated by the voltage, and produce another pairs, thereby amplifies the signal. The nonlinearity at the gain of 200 was less than 0.1% up to 140 thousand incident photons.*Hybrid type photomultiplier with Si diodeThis detector consists of cathode and PIN diode, and a voltage of about 10kV is applied between them. Photoelectrons from the cathode is accelerated, and produce about 2500 electorons per photoelectron when they hit the diode. The signal is detected by the PIN diode. This detector has an excellent linearity because of simple electron trajectory, and the good linearity of the PIN diode. The measured non-linearity was less than 0.1% up to 140 thousand incident photons.*Hybrid type photomultiplier with avalanche type Si diodeThis detector is same as the above except that it uses APD instead of PIN diode, to obtain higher gain. The measured non-linearity was about 6% at the gain of 5000, for 14 thousand incident photons. This large non-linearity was due to the avalanche photo diode itself, and it should in principle be more linear with a better APD.

我们建立了一个测试装置来测量线性度，精度为 0.1%。通过使用该系统，我们评估了以下新型光电探测器的线性度。*雪崩型光电二极管雪崩光电二极管（APD）上施加约1500V-2400V的偏置电压。进入p型硅的光子形成电子-空穴对。电子被电压加速，并产生另一对，从而放大信号。高达 14 万个入射光子时，增益 200 时的非线性小于 0.1%。 *带有 Si 二极管的混合型光电倍增管该探测器由阴极和 PIN 二极管组成，在它们之间施加约 10kV 的电压。来自阴极的光电子被加速，当它们撞击二极管时，每个光电子产生大约 2500 个电子。该信号由 PIN 二极管检测。由于电子轨迹简单，加上PIN二极管良好的线性度，该探测器具有优异的线性度。高达 14 万个入射光子时，测得的非线性小于 0.1%。 *带有雪崩型硅二极管的混合型光电倍增管该探测器与上述探测器相同，只是它使用 APD 代替 PIN 二极管，以获得更高的增益。对于 14,000 个入射光子，增益为 5000 时测得的非线性约为 6%。这种大的非线性是由于雪崩光电二极管本身造成的，原则上它应该随着 APD 的提高而变得更加线性。
