ap-2000	Antonelli, Antonella	THE NA62 EXPERIMENT AT CERN AND THE MEASUREMENT OF THE ULTRA-RARE DECAY K⁺→π⁺ v ̄v	2013	3	.pdf	application/pdf	2033	107	66	The Level 0 (L0) trigger algorithm is based on the presence of a charged particle in the RICH and veto conditions on LKr, LAV and muon veto detector, and is performed by dedicated custom hardware modules, with a maxi- mum output rate of 1MHz and a maximum latency of 1ms. Rejection of background from nuclear interactions of charged beam particles other than K+ will be guar- anteed by a differential Cherenkov counter (CEDAR) placed before kaons enter the decay region: Cherenkov photons radiated in a 6m long vessel, filled with he- lium gas, are focussed by an optimised optical system on eight fast PMTs.	cache/ap-2000.pdf	txt/ap-2000.txt
