Which of the following are true about dynodes used in discrete dynode electron multiplier?
A. The dynodes are all kept at same voltage
B. Successive dynodes are held at lower potential
C. Successive dynodes are held at higher potential
D. All dynodes are held at very low potential
Answer:C
Which of the following are true about dynodes used in discrete dynode electron multiplier?
A. The dynodes are all kept at same voltage B. Successive dynodes are held at lower potential C. Successive dynodes are held at higher potential D. All dynodes are held at very low potential
Explanation: In discrete dynode electron multiplier, successive dynodes are held at higher potential. Dynodes are metal plates with copper or beryllium surfaces.
