This ATLis has expanded to include hose replacement on JC dipole. While flushing these dipoles they are finding failing hoses and having to replace them. This is predominantly the jumpers and return hoses.

An East ARC LCW System low conductivity alarm (0.41 uS/cm) was generated at 4:01 PM which led to determined why conductivity was lower than the 0.5 uS/cm setting. Evaluation revealed the system was making up about every twenty-two minutes which indicated the system was leaking and the conductivity was low since the makeup water conductivity was lower than the normal system conductivity (see the attached pdf file). The Crew Chief was contacted at 4:15 PM and RADCON was called a few minutes later. A controlled entry was then made revealing a hose had failed.

All parties are out of the south LINAC after finding the leak at MJC5A24. A hose came out of the fitting. Mech Install is en route and DC Power is currently working on locking out the Arc 5 box supply.

Facilities needed to inspect SL Tunnel for leaks due to make-up water replenishing about every 20 minutes or so. No leaks found upstairs. Facilities and RADCON in SL now.

Hall D vertical dispersion check is about to happen.
Hall C tune beam looked good and ready for CW.
Hall B was taking 3nA CW until Hall D setup began.
