Hi All,

For those who have not heard there was a leak that developed after the ESR Crash last Saturday https://logbooks.jlab.org/comment/27425#comment-27425

The amount of leakage was approximately 300 liquid liters of helium per day. see: https://logbooks.jlab.org/entry/3790953

The leak was found in Hall B  see https://logbooks.jlab.org/entry/3791601

As a reminder, after ESR outages please review your systems that have low pressure relief valves (and any other reliefs that blow) to be sure that all relief valves have sealed.

Thanks
Dave
