论文摘要
作为2021年BDF工作组的主要重点的一部分，本文档报告了有关替代位置的研究以及可能伴随现有设施的可能优化的研究，目的是大大降低该设施的成本。在BDF/船舶综合设计研究（CD）的基础上，评估取决于通用要求和约束条件，可以通过使用$ 4 \ times 10^{19} $ protons每年400 \，GEV，GEV，GEV，目前没有在SPS上没有利用的GEV，并且对于现有的设施均不得不兼容，从而保留了该设施的物理范围。考虑的选项涉及地下区域TCC4，TNC和ECN3。还提到了当前位置（称为“ TT90-TCC9-ECN4”）的BDF设计的最新改进，并提到了进一步改进的想法。对替代位置的评估汇总了已经提供的大量信息以及2021年期间进行的一系列概念研究。 该文件以定性比较的期权进行结论，总结了每种选择的相关利益和挑战，以便可以提出有关要选择哪个位置的建议。确定了指定每个选项的实施和成本所需的最关键的特定位置研究，以便可以在2022年底之前完成对保留期权的详细研究。
As part of the main focus of the BDF Working Group in 2021, this document reports on the study of alternative locations and possible optimisation that may accompany the reuse of existing facilities with the aim of significantly reducing the costs of the facility. Building on the BDF/SHiP Comprehensive Design Study (CDS), the assessment rests on the generic requirements and constraints that allow preserving the physics reach of the facility by making use of the $4\times 10^{19}$ protons per year at 400\,GeV that are currently not exploited at the SPS and for which no existing facility is compatible. The options considered involve the underground areas TCC4, TNC, and ECN3. Recent improvements of the BDF design at the current location (referred to as `TT90-TCC9-ECN4') are also mentioned together with ideas for yet further improvements. The assessments of the alternative locations compiled the large amount of information that is already available together with a set of conceptual studies that were performed during 2021. The document concludes with a qualitative comparison of the options, summarising the associated benefits and challenges of each option, such that a recommendation can be made about which location is to be pursued. The most critical location-specific studies required to specify the implementation and cost for each option are identified so that the detailed investigation of the retained option can be completed before the end of 2022.
