About
The PMT-176 is a spectrometric photomultiplier tube designed for photometry, spectrometry, and γ-radiation detection using the scintillation method. It is intended for use in diagnostic radioisotope equipment and finds application across ecology, biophysics, geology, geophysics, nuclear physics, and high energy physics. The device features a multialkali photocathode of S20 type, an electron electrostatic focusing system, and a 12-dynode multiplication system. It has a photocathode diameter of 40 mm, an overall device diameter of 52 mm, and a length of 120.5 mm. Its spectral response range spans 300 to 850 nm, with a photocathode luminous sensitivity of 130 μA/lm, a dark current of 8 nA, a supply voltage of up to 1500 V, and a gain under normal conditions of 1·10^5. The product was first released in 1986, has a guaranteed service life of 4 years, and an estimated production/delivery time of 3 months. It is not flight-qualified, but it can be adapted to customer requirements.
