Jian-Ping and I spent about 4 hours realigned all the lasers.
Now all look pretty good and we just started pumping up the cell.
The RTDs were checked:
- RTD#4 died after the beam shot it.
- RTD#6 and RTD#7 are working fine but the ADC for RTD#6 is not working. Kathy looked at it. It was working for a while and crashed again. So I switched again the connection to get the readback of RTD#6 in RTD#7 GUI readback. RTD#6 is more important since it sees most of the laser light.
The lasers had some problems too:
- Laser Coherent#5 died and will be sent for repair.
- Laser Coherent#2 had its diode changed one month ago and when we turned it on, we heard a very bad noise from the fan. So it will be also repaired. Todd Averett brought us one of his lasers.
