APEX Summary -- June 9• 10 Hz ramp feedback: Largely successful, unable to test turn-off for rebucketing• Dynamic beta* squeeze• Q1 modulation beta* measurement•Beam-beam space charge• Setting up beam conditions, collisions takes longer than anticipated

• IP transfer matrix• Delayed start transitioning from previous experiment, poor injection• Tripped sextupole made tune measurements difficult

• Local decoupling• Tried to recover time by working in parallel, but unsuccesfully• Then weather….
