The orbit of the beam in the ring was re-configured so that the beam position is more central.

With the target density at ~6e11 at/cm2 this allowed a target overlap scan using the beam lifetime to be performed. 

Beam put into bunched mode to allow the number of particles to be observed on Grafana.

The number of particles injected at the start of the cycle was then compared to the number of particles at the end of the cycle to gauge the % of the beam lost.

A flat top region was observed where >99% of the particles in the ring were lost. The centre of this flat top corresponds to a horizontal beam position of 1.0 mm
