Sensor fixation

2019/6/27 2

This week I used glue again to fix th e

sensor.

After gel remover, there is still a lot of

glue on the sensor surface.

I can’t measure the I-V.
The reason may be that the glue on

the back of the sensor has not been removed.

Another method: Use Kapton tape which use by Koji

The status after irradiation

Kapton tape pack sensors by Al foil the Glass Fiber plate

Liquid Nitrogen Test

1. We borrowed a liquid nitrogen tank about 30L
2. Right picture is a simple test of work temperature and usage time

Liquid Nitrogen Test

T1 T2

1. If temperature control at -10C, liquid nitrogen can work two hours

 We need about 8 hours. Prepare to design closed box and temperature control device

2. T1, T2 temperature is not much different
3. The sensor is packed in aluminum foil to protect sensor.
