Abstract. The pixel recovery time of the Hamamatsu SiPM linear assembly was measured. The assembly contains eight SiPMs of 2.8 mm active area diameter; pixel size is 15 x 15 mkm2. The assembly is used in calorimeters of the CMS experiment.
The measurements were made for two groups of pixels: 49 and 17 pixels. Recovering time was found as 7 ns and 6 ns respectively.
The amplifier of 40 db and digital oscilloscope TDS3052 Tektronix were used when measurements.
