YBBS06 T14 coil temperature is trending upwards again. Based on the trend, its possible that it will take another two days to trip on high temperature.

Due to the issues with MZAAS04, beam is not possible to transport past 8S. Arc 7 is not required for beam transport as we are extracting 1st pass and 3rd pass.

Therefore we will leave Arc 7 Box supply OFF until there is an opportune time to flush the YBBS06 again. This has been discussed with DC power and CASA and they have agreed.

YBBS06 has been downgraded in SRM/HCO.

During our investigation of MZA8S03, I found that the downstream magnet, MZAAS04 had broken brackets and the kapton flaring up off the magnet (Fig. 2). MSS took a closer look and you can see the coils protruding out the top of the magnet (Fig. 1). If you look closely, it appears the beam pipe is being pushed upwards on the incoming left side and then bending back downwards on magnet exit (Fig. 3).

This magnet will be downgraded in SRM.

All magnets on the RSEP8A string are in regions 8S or downstream.
