← ScienceWhich outcome primarily results when a photomultiplier tube's dynode voltage exceeds its design limit?
A)Increased electron cascade background noise✓
B)Lower photoelectric conversion efficiency
C)Reduced gain amplification saturation
D)Improved linearity regarding photoelectron emission
💡 Explanation
Increased electron cascade background noise occurs because exceeding voltage limits causes increased field emission through impact ionization within successive dynodes. Therefore the noise rises because of spurious electron multiplication, rather than signal boost or better linearity.
