Motivation
We have two kind of samples aiming for the upgraded ECL (in super Belle). Photopentode (PP) x3 Avalanche photodiode (APD) x4
We hope to know the stability of their gain factors.

Cool the air inside the black box
In Taipei, the weather in summer is very hot. We hope to reduce the testing temperature. (similar as in KEK.)
Cooling module: 15*15*3.3mm

Results of P.P. (3 piece)
We can’t repeat our previous measurement results. Problem is
After checking our circuits with Kuzmin-san, we found our diode-mode circuit was wrong. Now, we know how to fix it.

Results of APD (4 piece)
It takes 20 minutes to finish the data taking.
The data record period is 1s.The temperature precision is 0.1℃.

Summary
APD measurement is more or less normal.
We met problems for PP measurement. But we know how to fix it now.
