Mu3e 是 Paul Scherrer 研究所即将进行的一项实验，旨在寻找 $\mu\rightarrow eee$ 的强烈抑制衰变。它将采用超轻硅像素探测器，采用薄型 HV-CMOS MAPS 芯片。通过使用由铝制成的高密度互连件并在氦气氛中操作探测器，可以进一步控制多重库仑散射。超过 1 m2 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要求相冲突，因此将采用气态氦流冷却系统。本次演讲将报告在实际条件下以 1.25 Gbit/s 的目标速度使用铝互连进行的成功数据传输测试。氦冷却的最终概念验证已经通过全面的冷却模拟实现，并通过使用顶点像素探测器的全尺寸模型的实验室测量成功得到证实。
Mu3e is an upcoming experiment at Paul Scherrer Institut in the search for the strongly suppressed decay of $\mu\rightarrow eee$. 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.
