We'll meet in TL-2561a on June 5, 2019 @ 9:30am.

Unusual Circumstances

There have been 3 recent incidents where fire trucks responded to alarms on the accelerator site:

1. May 21, 2019 - 10A card in a 1A slot resulting in a burned up air core magnet at 0L09 - https://logbooks.jlab.org/entry/3683097
2. May 30, 2019 - Mis-wired 25A short on 100A shunt resulting in burned insulation on a ZA magnet - https://logbooks.jlab.org/entry/3684466
3. May 31, 2019 - Failed transformer winding on 28 year old klystron cathode power supply - https://logbooks.jlab.org/entry/3684618

In our realm of the accelerator, have we had enough resources and time to reasonably assess our systems and have confidence for high reliability this summer?

The next 7 months!
