Production and Test of sPHENIX W/SciFiber Electromagnetic Calorimeter Blocks in China

请选择邀稿期刊:
摘要:     The sPHENIX experiment is a new generation of large acceptance detector at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory with scientific goals focusing on probing the strongly interacting Quark-Gluon Plasma (QGP) with hard probes of jets, open heavy flavor particles and $ Upsilon$ production. The EMCal detector, covering the pseudo-rapidity region of $ eta leq 1.1$, is an essential subsystem of sPHENIX. In this paper, we focus on the production and test for the EMCal blocks covering a pseudo-rapidity of $ eta in 0.8 , 1.1 $. These, in conjunction with central pseudo-rapidity EMCal blocks, significantly enhance the sPHENIX physics capability of jet and $ Upsilon$ particle measurements. In this paper, detector module production and testing of the sPHENIX W-powder/Scintillating Fiber (W/ScFi) Electromagnetic Calorimeter Blocks are presented. Selection of the tungsten powder, mold fabrication, QA procedures and cosmic ray test results are discussed.
