LPKF ProtoLaser U4 Laser router

我们建议购买LPKF Protolaser U4激光路由器，以开发制造超低质量、多层、高密度铝/Kapton柔性电路的能力，作为开发未来粒子物理实验用低质量硅探测器元件的关键部分。这些低质量结构是未来探测器发展的关键部分，因为降低这些系统的质量减少了粒子和探测器本身之间的多重散射相互作用，使粒子轨迹的确定更加精确，并允许进行更灵敏的物理测量。该系统将与牛津大学物理系中央电子集团（CEG）目前的PCB生产设施集成，并将作为小型研究设施（SRF）计划下的一套可访问制造工具的一部分提供给牛津大学和更广泛的实验物理社区。它将得到已经在该领域工作的专家工程团队的支持和开发，以获得最大利益。它补充并加强了牛津大学已经开展的低质量开发活动，作为Mu 3e合作的一部分，我们负责外部像素阶梯的建设。将这种能力引入内部的主要好处是：将原型制作时间从目前与外部供应商合作的大约三个月缩短到几天。这将允许一种完全不同的工作模式，并将显著提高电路设计的性能。为了提高生产的稳健性，因为目前全球只有两家制造商。为了使工程设计团队更接近生产，以进一步优化和集成设计，充分利用技术。为了降低原型制作成本。目前，每次原型设计的最低成本为7，500英镑（含税），这使得对先进设计的多次试验成为不可能。这与STFC核心计划拨款ST/W 000628/1有关。

We propose to purchase an LPKF Protolaser U4 laser router to develop the capability to fabricate ultra-low-mass, multilayer, high density, aluminium/Kapton flex circuits as a key part of developing low mass silicon detector elements for future particle physics experiments. These low mass structures are a crucial part of future detector development, as lowering the mass of these systems reduces the multiple scattering interaction between particles and the detector itself, making the determination of particle tracks more precise, and allowing more sensitive physics measurements to be made. The system will integrate with the current PCB production facilities of the Oxford Physics Department Central Electronics Group (CEG) where it will be available to Oxford groups and the wider experimental physics community as part of an accessible suite of fabrication tools under the small research facilities (SRF) scheme. It will be supported, and exploited, to maximum benefit by an expert engineering team already working in this field. It compliments and enhances the low mass development activities already undertaken at Oxford as part of the Mu3e collaboration, where we are responsible for the construction of the outer pixel ladders. The principle benefits of bringing this capability in house are: To shorten the prototyping time from approximately three months currently with an external supplier to a few days. This will allow a completely different mode of working and will significantly improve the performance of the circuit designs.To increase the robustness of production, as there are currently only two manufacturers available worldwide.To bring the engineering design team closer to the production to allow further optimisation, and integration of the design, making full use of the technology.To reduce the cost of prototyping. There is currently a minimum cost per prototyping run of £7,500 plus tax, which makes multiple trials of advanced designs prohibitive.This relates to STFC core programme grant ST/W000628/1.
