About
The Photomultiplier Tube of High Immunity to Magnetic Fields (tetrode), also known as PMT-tetrode, is designed for scintillation irradiation detection in high energy physics applications under demanding environmental conditions, including magnetic fields of up to 1.2 T and radiation doses of up to 1500 Gy. It was released in 2009 and offers a guaranteed service life of 4 years, with an estimated production/delivery time of 3 months. The product has not undergone flight qualification but can be adapted to customer requirements. Structurally, the PMT-tetrode features a bialkali (SbKCsO) photocathode with a two-cascade multiplication system, and its input window is made of boron-silicate UV glass. Key parameters include a photocathode diameter of 16 mm, overall device diameter of 22.2 mm, and length of 46 mm. It has a broad spectral response range of 220 to 650 nm, photocathode luminous sensitivity of at least 60 μA/lm, low dark current of no more than 2 nA, and operates at a supply voltage of 1200 V. Photocathode quantum efficiency at 420 nm wavelength is at least 15%, and the device maintains a gain of at least 13 even under a strong magnetic field of 1.2 T, making it suitable for use in high-radiation, high-magnetic-field detection environments typical of particle physics and space-related scintillation detection systems.
