CERN 开发的用于前端系统供电的低噪声 DC-DC 转换器能够为 HL-LHC 的物理实验实施高效的供电方案。最近对 ATLAS 短带跟踪器模块进行的测试证实了 DC-DC 转换器原型与前端探测器的完全电磁兼容性。跟踪器前端中转换器的集成还需要解决材料预算限制。讨论了 DC-DC 转换器对 ATLAS 跟踪器模块材料预算的影响，并探索了质量减少技术，从而在电磁兼容性和质量之间取得折衷。提出了低质量屏蔽实现和铝芯电感器。此外，还讨论了关键部件尺寸减小对发射噪声的影响。最后，讨论了电路板布局和制造层面的材料减少技术。
The development at CERN of low noise DC-DC converters for the powering of front-end systems enables the implementation of efficient powering schemes for the physics experiments at the HL-LHC. Recent tests made on the ATLAS short strip tracker modules confirm the full electromagnetic compatibility of the DC-DC converter prototypes with front-end detectors. The integration of the converters in the trackers front-ends needs to address also the material budget constraints. The impact of the DC-DC converters onto the material budget of the ATLAS tracker modules is discussed and mass reduction techniques are explored, leading to a compromise between electromagnetic compatibility and mass. Low mass shield implementations and Aluminum core inductors are proposed. Also, the impact on emitted noise due to a size reduction of critical components is discussed. Finally, material reduction techniques are discussed at the board layout and manufacturing levels.
