VPTT RIE 22.5+0-0.7 mm ≤ 46 mm Tetrode 5.2.09 see note
Note VPTT: Electrical connections will be 100±5 mm in length, made of copper flexible wires (PVMP-2 type) having a cross section of 0.12 mm2 with 1.6 mm-diameter polyethylene insulation, capable of withstanding a voltage up to 6 kV. The VPT’s base (socle) will comprise a cylinder, 14 mm in length, made of insulator (type K-8 vicsint). The wires shall be color coded as follows: white (anode), yellow (cathode), blue (1st dynode), brown (2nd dynode).
