[Luke, Luis]
The vacuum chamber is currently baking.
We stepped up to 125°C by increments of 30°C starting at 60°C. Everything went fine. After about 20 minutes of the PID controllers being set to 125°C, the flange closest to the RGA was 38°C, so we left it connected.
Current state as of 4:15:
The gate valve is open, and the filament of the RGA is on.
The temperatures are as follows:
PID right barrel upper: 105°C, RGA volume: 125°C
PID left barrel lower: 125°C, Lid: 82°C
The lower temperatures should climb as the whole system heats up.
I will come in Saturday afternoon to turn them off so that we can look at the pressures on Monday. |
