Extras ▼

 

The CMG22 is a gas filled photocell with a caesium on silver cathode.
The labels give the equivalent as the CV1473 and the anode voltage to use as 100 V.
The anode is a wire rectangle placed in front of the photo-cathode.
The cathode seen face on has the approximate area of the anode aperture but the shape would allow for off-axis illumination.
The coated cathode plate is a rectangle bent with a 90 ° included angle. Our CV1473 has a semi-circular cathode.
The wide glass tube envelope is 25 mm in diameter, and excluding the B4 base pins is 57 mm tall.
