Upper part of the frame was mounted. In order to do so, the valve was closed, turbo wire and hose were disconnected and then connected. Valve was opened
again. See pictures 1-2.
Bottom part of the tent was constructed with 3 heaters (from one of the controllers) at the front, 4 in the middle, and 4 at the back (4+4 from |

Thu Nov 11 11:44:58 2021, RSS + ML OG + CB (remotely), CARME baking started
|
With the help of OG, the baking tent was built. MG started baking around 11:30 am with a rate of 0.2 K/minute.
Heating update can be found on: https://web-docs.gsi.de/~lestinsk/baking.php (CARME temperature plot now visible as well - thanks Michael!)
where, device - 192.168.207.192 is for CARME. |

Most of the CARME is covered by the baking tent. The tent needs to be closed and a bit covered from the front
(upstream), end (downstream), and bottom side. TCs are labeled with a marker in the sequence 1-1 to 2-8.

We opened one up and soldered a co-ax cable to one of the +6v power contacts at the output of the filter board.
Connecting this to a 'scope we observed a level of +/- 5mv noise with no FEE connected.
Connecting one FEE made little difference. |

This is a suggested sequence of actions to help with the current problem with the White Rabbit timestamp distribution. Test the system between each intervention.
If a test provides an answer to the problem then proceed accordingly rather than continue with the suggestions.
Please sketch the current MACB wiring.
Unplug and replug the connectors of the VETAR HDMI connecting cable. If possible clean |
