Wednesday, June 19, 2019, 17:13 Ferran and Fernando tested the 9-pin connector to have a reading on a thermocouple following the connections used
by Aurelia (see elog 721).

|
Tuesday, June 25, 2019, 16:15: While inspecting the 9-pin connection with Ferran, it was noticed how two braided cables were burnt out pretty bad to
the point they were separated in half (see attached pictures). Additionally the plastic insulator for the anode wire was melted.
Tuesday, June 25, 2019, 16:30: Braided cables need to be changed and anode wire redone. |

Inserted a used (heating) LP-FEBIAD target with a basic heat shield assembly with no end plate foil on the window side to observe heating. The P2N Coil

Test whether the TS connections are affecting the P2N heating or if it's the P2N target itself. |

The idea is to change the cables to have individual signals. This will allow 4 thermocouple readings.
NB: The FT is not vacuum tight as of now (gasket needs to be replaced and flange needs to be tight) |
