CDF II新型中央和前向μ介子计数器的设计和建造
Design and construction of new central and forward muon counters for CDF II
摘要:
为了完成中央CDF探测器的μ子覆盖范围,并将覆盖范围扩展到更大的赝快度,已经为CDF升级设计和建造了新的闪烁计数器。一种新的光收集技术,使用波长漂移光纤,连同高品质的聚苯乙烯基闪烁体导致在长度延伸到320厘米的紧凑的计数器具有良好和稳定的光收集效率。他们的设计和施工进行了说明,并报告其初步性能的结果。
英文摘要:
New scintillation counters have been designed and constructed for the CDF upgrade in order to complete the muon coverage of the central CDF detector, and to extend this coverage to larger pseudorapidity. A novel light collection technique using wavelength shifting fibers, together with high quality polystyrene-based scintillator resulted in compact counters with good and stable light collection efficiency over lengths extending up to 320 cm. Their design and construction is described and results of their initial performance are reported.
