Emittance meter number 2 ready for beam shortly - installed and pumping down.
No beam found by Thursday evening, but beam seems to be coming out much differently than last time. Will check on emittance meter functionality
and try to re-tune later. |

Swapped the old 9pin connectors out and replaced with 2 5-pin connectors, same as on the modules.
See attached for current pin out diagram. Many of the wires are too short to reach the bottom sockets, so wires 2, 8, 9 are not connected in the
connector. 4 spots are empty on connector 2 (right). (6, 7) and (4, 5) are twisted pairs. Unused wires are tapped up out of the way, but we should |
