This is an Hamamatsu R1328U-02 ultra-fast biplanar phototube with padded case. The R1328U-02 is equivalent to the R1328U-52 with regards to performance, the only difference being the HV connector which is MHV on this model.
The R1328U series have very fast time response, such as 60 picosecond rise time and 55 picosecond fall time and excellent impedance matching. These characteristics make it possible to reproduce precise waveform of light pulses with extremely less ringing.
