<p>Chendi,</p>
<p>I agree with Xiaochao that the Gain-V relation is linearity under
double-log axis as shown on the PMT specification sheet, not
single-log axis. You should contact with the PMT company to
explain why the Gain-V results is not linearity under double-log
axis.</p>
<p>Your PMT Gain raises much more, it should be the reason the NPE
decrease.<br>
