Photon Counting Mode

At present, matrix multi-element avalanche photodetectors operating in the photon counting mode are widely used for detecting optical radiation. However, the char-acteristics of matrix multi-element avalanche photodetectors operating in this mode are currently insufficiently studied. Prototypes of Si-photomultiplier tubes (Si-PMTs) with a p+–p–n+ structure produced by JSC Integral (Republic of Belarus), as well as serially produced silicon photomultipliers Ketek PM 3325 and ON Semi FC 30035 have been used as objects of research. This article presents the research results of characteristics in the photon counting mode of the specified photodetec-tors. The dependences of the specific amplitude sensitivity ratio on the wavelength of optical radiation, the temperature, the supply voltage of the matrix multi-element avalanche photodetector are determined.

Currently, in many applications, photodetectors are needed that provide registration of optical radiation in a wide range of intensities and allow combining two operating modes: current mode and photon counting. These devices include silicon photoelectronic multipliers (SiPM), which have a number of advantages compared to electrovacuum photomultipliers and avalanche photodetectors. However, the influence on the photoresponse characteristics of SiPM of such important factors as the supply voltage and temperature has not been studied enough. The influence of these factors on the amplitude parameters of the photoresponse of SiPM is studied. The block diagram of the experimental setup is presented, with the help of which the photoresponse characteristics of SiPM with n+-n-p+ and p+-p-n+ structures manufactured by Integral OJSC (Republic of Belarus) were measured. The dependences of the average amplitude of the photoresponse on the supply voltage and temperature of silicon photomultipliers for various wave-lengths of optical radiation are presented. It was found that when SiPM were exposed to optical pulses with the same duration and energy exposure at the same temperature at the same overvoltage, the photoresponse amplitude was larger for a SiPMr with p+-p-n+ structure regardless of the wave-length of optical radiation. It was found that, when the overvoltage changes, the increase in the photoresponse amplitude is observed only in the overvoltage range ΔU = 0 ¸ 3 V for all the studied SiPM, irrespective of the wave-length of the detected optical radiation and temperature. It was determined that a decrease in temperature led to an increase in the amplitude of the photoresponse pulses. The temperature dependence of the amplitude of the photoresponse was most pronounced for SiPM with the p+-p-n+ structure. It was shown that the dependences of the average amplitude of the photomonitor Si-PM on the energy exposure have a linear section, the length of which depends on the wavelength of the detected optical radiation.

Skorina st., Minsk, 220114, BelarusE-mail: [email protected] January 12, 2021Recently multipixel avalanche photodetectors, called silicon photomultipliers are of-ten used to record optical radiation. The influence of ambient temperature and sup-ply voltage on the spectral sensitivity and dynamic range of prototypes of silicon pho-tomultipliers manufactured by JSC "Integral" (Republic ofBelarus) and commercially available photomultipliers KetekRM 3325 and ON Semi FC 30035 has been investigated in this article. It was determined that the spectral sensitivity maxi-mum of silicon photomultipliers is shifted to the short-wavelength region andcorre-sponds to the wavelength of optical radiation of 470 nm. It is shown that an increase in the supply voltage leads to an increase in the sensitivity of the investigated photodetectors, and the dependence of the sensitivity on temperature manifests itself in different ways when exposed to optical radiation of different wavelengths.

Stellar Image

The Precision CAlcium Photometer (PCAP) has been built with characteristics optimized for amplitude astroseismology. The instrument consists of two units: an on-telescope optical system that forms and stabilizes a stellar image onto a 200 micron optical fiber; and a spectrometer unit that accepts the light from the fiber and integrates the Calcium II H and K lines (3968.5 Å and 3933.7 Å), along with adjacent continuum regions, in a photon-counting mode. Some key system characteristics include active image stabilization, a 12-meter optical fiber with ~70% transmission at 3950 Å, and a thermally and mechanically stable spectrometer. A description of the instrument and of laboratory and on-telescope test runs are discussed below.
