[Esr-users] Cool down of SHMS dipole

All,

Based on Chris Perry's email from yesterday, ESR is already running at an elevated load.  Therefore, I recommend not cooling the SHMS dipole until this is resolved and we can be assured that the cooldown will not affect the running Halls.

Regards,
Bob Miller
Hall B Lead Engineer

Hi David,

Just for the record, I do not have any objection to Hall C starting cool down of the SHMS dipole on Friday if it can be supported by the ESR/CHL complex without affecting the running halls and meets your standards of readiness (e.g. contamination).  I leave it to the engineers however to determine if this is the most appropriate path forward.

Thanks - Javier
