SUMMARY
An increase in amplifier gain in a setup involving a Photomultiplier Tube (PMT), amplifier, and Multi-Channel Analyzer (MCA) does indeed cause the peak to shift towards higher channels. This phenomenon occurs due to the amplification of the signal, which enhances the visibility of weak sources but also introduces noise. Users often face a trade-off between gain settings and noise levels, as higher gain can make weak peaks discernible while lower gain may obscure them.
