BNL Belle II Operations Activities


• KLM commissioning– KLM team sought additional effort to commission KLM. – Worked with Virginia Tech, U. Hawaii and Belle II Ops Manager L.Wood to

bring on-board BNL postdoc Brian Kirby for Feb-Aug2018. • Intensive debug of firmware before/during Phase II• Verified >90% scintillator layer efficiency• Successfully implemented scintillator readout during Phase II• Participated in UH workshop to commission KLM test stand• Trained UH postdoc as replacement

– BNL conducted Belle II KLM readout firmware technical review 3-4 May 2018. • Committee members: Joseph Mead(chair), Hao Xu, Kai Chen of BNL NPP, Lynn

Wood of PNNL. • Committee Recommendations were adopted:

– Establishment test stand for KLM scintillator (at U. Hawaii)– Simplified scintillator readout for Phase II to be able to join DAQ

• Belle II DAQ upgrade (see separate presentation)
