The PLC CPU came out of the socket around 11:50am today (Dave Morris). The CPU had not been properly attached. This resulted in full stop of all power
supplies and vacuum pumps.
Restarted vacuum pumps at 12:10pm (20 min later). |

First P2N heating test ongoing.
At P2NHT ~ 570 A and TBHT ~ 100 A shine is already seen, which suggests that current is flowing in the P2N target properly, see picture attached. |

Beginning of May:
The cabling on the top of the test stand was changed to adapt for P2N testing. The TGHT and COIL PS were disconnected, and their DC cable terminals
were connected instead to the TDK-LAMBDA P2Nheaters. The configuration on top of the ITS module is the following: |
