Cabling |
Taka negotiated with Juan Calvo to release the hot air in the lab. Juan refused. The hole in the wall of the lab for air release will be made next week. We borrowed a pulse generator from IAC for trigger for the laser. But we discovered that there is no lemo connector at IAC. We asked Javier for help, and he agreed to bring some from LaPalma at the end of this week. |

We connected the 380 V from the wall to PSU and got 24 V for the first time. It is working fine. QC measurements on 1 Italian Dragon was performed, finding no problem. Air pipe from the spot cooler is still an issue. |

Cabling |
We need 380 V input for the power supply. It can be provided by the wall of the clean room but the outlet is 15 m away. Such cable was not in IAC. We went to the electric shop El Faro, but they had only connectors. |
