THE DESIGN AND CONSTRUCTION OF THE BARREL SHOWER COUNTER FOR BES
【摘要】 本文描述了北京谱仪(BES)桶部簇射计数器(BSC)的设计与建造.桶部簇射计数器为圆桶形,内径2.5m;外径3.4m;长3.85m,承重铝桶直径为2.5m;厚3cm;长4.23m.由23层铅(每层0.5r.1.)和24层自猝灭流光(SQS)管组成,重40吨,覆盖立体角为4π×80%.
【Abstract】 The design and construction details of the barrel shower counter for BES are discussed.The barrel shower counter is cylinderical,of 2.5 m inner diameter,3.4m outer diameter and 3.85m length,constructed on an aluminum spool of 2.5m diameter,3cm thickness and 4.23m length.There are 23 layers of lead(0.5r.l.as an absorber)and 24 layers of selfquenching streamer(SQS)tubes.The total weight of the counter is 40,000kg and 80% of 4π sr soild angle coverage.
