论文摘要
MU3E是Paul Scherrer Institut即将进行的实验，以寻找$μ\ Rightarrow EEE $的强烈抑制衰减。它将使用稀释的HV-CMOS映射芯片使用超轻质硅像素探测器。通过使用由铝制成的高密度互连并在氦气大气中操作探测器的高密度互连，进一步控制了多个库仑散射。超过1平方米的仪表表面将产生约3.3 kW的热量（$ \ leq $ 250 mw/cm2）。传统的冷却方法与低质量需求相抵触，因此将实施气态的氦流冷却系统。本演讲将在现实条件下以1.25 GBIT/s的目标速度与铝互连进行成功的数据传输测试报告。通过全面的冷却模拟，已经实现了氦冷却的最终概念验证，并通过使用顶点像素探测器的全尺度模型成功地确认了实验室测量。
Mu3e is an upcoming experiment at Paul Scherrer Institut in the search for the strongly suppressed decay of $μ\rightarrow eee$. It will use an ultra-lightweight silicon pixel detector using thinned HV-CMOS MAPS chips. Multiple Coulomb scattering is further kept under control with using high density interconnects made of aluminium and operating the detector in a helium atmosphere. More than 1 m2 of instrumented surface will produce about 3.3 kW of heat ($\leq$ 250 mW/cm2). Traditional cooling approaches are in conflict with the low-mass requirements, hence a gaseous helium flow cooling system will be implemented. This talk will give a report on the successful data transmission tests with the aluminium interconnects at target speeds of 1.25 Gbit/s under realistic condition. The final proof-of-concept of the helium cooling has been achieved with comprehensive cooling simulations and successfully confirmed with laboratory measurements using a full-scale mock-up of the vertex pixel detector.
