Operator: hasell

Shift started out running smoothly. Injecting at 225 with a lifetime of 28 minutes.

Around 11:00, near the end of run 15171 the polarised source developed some power supply problems. CCR could not refill the ring so kept the beam in the ring and continued taking data.

Started run 15172 with the remnants of the beam in the ring but CCR had further problems with a flow switch and lost the beam after only 58K events.

Beam back at 12:30 and everything running smothly again

Runs 15170-15179
