The HR1/60/0.5 is a small industrial cathode-ray tube. The first digit 1 indicates a single beam tube, the 60 is the screen diameter in mm and the 0.5 is the final anode voltage expressed in kV. The first anode voltage is 180 V.
The deflection sensitivities are 0.18 mm/V and 0.13 mm/V. The X and Y capacity is 3.5 pF and the grid capacitance is 11.5 pF.
