Measured Beam Energy Loss
	• ~ 60 “Tevatron-style” ionization monitors: – 100 second running average now our primary figure of merit for Booster performance. – Part of Booster permit system. • Differential proton loss is measured using toroids. –  Weighted by energy to produce a “Beam Energy Lost”. –  Loss rate in Watts calculated using a 5 minute running average updated every minute. Part of Booster permit system (current limit 400 W).
