Opis:: The paper presents method for thermal generation reduction in low level light applications, especially where measured phenomena have random character. The algorithm was developed basing on cosmic ray measurements. The main parts of the system are: Silicon Photomultipliers (SiPM), front-end ASIC for amplifying and shaping signals. SiPM is a very sensitive device which can detect single photons. Comparing to a standard photomultiplier SiPM has a compact size, low operating voltage and it is immune to an electromagnetic field. Thermally generated signals are disadvantage of SiPM. This paper presents the measurement method to reduce influence of thermal generation.

Opis:: The paper stresses the issue of strong temperature influence on the gain of a Silicon Photomultiplier (SiPM). High sensitivity of the detector to light (single photons) requires stable parameters during measurement, including gain. The paper presents a method of compensating the change of gain caused by temperature variations, by adjusting a suitable voltage bias provided by a precise power module. The methodology of the research takes in account applications with a large number of SiPMs (20 thousand), explains the challenges and presents the results of the gain stabilization algorithm.

Opis:: In the paper a measurement method of fluorescence intensity reduction (called photobleaching) caused by excitation light was presented. Intensity of fluorescence light was measured by silicon photomultiplier (SiPM) – sensor which allows single photons detection. It has more compact dimensions and lower bias voltage in comparison to photomultiplier tube, presently used in many laboratory devices. Standard photometric cuvettes with a capacity of 1.6 ml and optical path length of 10 mm were used for the measurements. Sodium fluoresceinate dissolved in 10 mM TRIS buffer at pH 8.5 was used as the fluorescent dye. The solution was tested at a concentration of 100 μg per ml with constant excitation light from LED source over the time of measurement.
