论文摘要
我们表征了S14160-3050HS多像素光子计数器（MPPC），这是由Hamamatsu Photonics K.K.生产的高效率，单道通道硅光电层次。所有测量值均在室温（23.0 $ \ pm $ 0.3）$^{\ circ} $ c下进行。 We obtained an I-V curve and used relative derivatives to find a breakdown voltage of 38.88 V. At a 3 V over voltage, we find a dark count rate of 1.08 MHz, crosstalk probability of 21 $\%$, photon detection efficiency of 55 $\%$ at 450 nm, and saturation at 1.0x10$^{11}$ photons per second. S14160-3050HS MPPC是超快速天文学（UFA）望远镜的候选探测器，该望远镜将在毫秒内的光学（320 nm-650 nm）天空（320 nm-650 nm）的天空来表征，使用两个光子计数阵列在0.7米米及其concecient上进行，以下是微米秒。天体物理天文台（Nuttela-tao）位于哈萨克斯坦Almaty附近。我们讨论使用S14160-3050HS MPPC用于UFA望远镜和未来地面望远镜的优势和缺点。
We characterized the S14160-3050HS Multi-Pixel Photon Counter (MPPC), a high efficiency, single channel silicon photomultiplier manufactured by Hamamatsu Photonics K.K. All measurements were performed at a room temperature of (23.0 $\pm$ 0.3) $^{\circ}$C. We obtained an I-V curve and used relative derivatives to find a breakdown voltage of 38.88 V. At a 3 V over voltage, we find a dark count rate of 1.08 MHz, crosstalk probability of 21 $\%$, photon detection efficiency of 55 $\%$ at 450 nm, and saturation at 1.0x10$^{11}$ photons per second. The S14160-3050HS MPPC is a candidate detector for the Ultra-Fast Astronomy (UFA) telescope which will characterize the optical (320 nm - 650 nm) sky in the millisecond to sub-microsecond timescales using two photon counting arrays operated in coincidence on the 0.7 meter Nazarbayev University Transient Telescope at the Assy-Turgen Astrophysical Observatory (NUTTelA-TAO) located near Almaty, Kazakhstan. We discuss advantages and disadvantages of using the S14160-3050HS MPPC for the UFA telescope and future ground-based telescopes in sub-second time domain astrophysics.
