That is Great progress, Kevin. I was there yesterday late afternoon. I guess you still has a lot of low level PLC work. Do you need me to be with you tomorrow? I plan to be there for something else, but I can redirect my work for the LERF. If you are going
to have RF power to generate, I need to bring RF power meter and spectrum analyzer to there too.</div>

<div class="" style="word-wrap:break-word; line-break:after-white-space">The magnetron commissioning OSP is signed off, we had a walk through with Harry Fanning, Phillip Stanley, Bonnie Rodriguez, Billy Formichelli, Charlie Garrison, & myself. The locks were
removed & breakers energized to the transmitter cabinet. The two 480 VAC breakers on the transmitter are both remote lever/cable actuated so, per procedure, there are no arc flash hazards when turning these levers ON/OFF as long as the main cabinet door is
closed. Three of the four AVTs have been tested - the fourth is for the 480 VAC supply to the high voltage transmitter transformer & will be tested when all interlocks are satisfied. Next steps are to fill the cooling water circuits & test interlocks - if
all goes well we should make some RF next week.
<div class="">Thanks all for the support!</div>
