Discussion
17:05 - 17:20
Few open points for follow-up: - Optimize losses in RCS chain for best overall performance, allowing different transmission in the two or three machines - Acceptable longitudinal emittance growth in the RCS chain and how to quantify it exactly? - Would two RCS be sufficient to accelerate from 60 GeV to 1.5 TeV? - Cost functions per machine part: could one make an assumption for a cost per unit length of RF (plus some infrastructure cost offset per RF section), idem for unit length of magnets? - Average gradient of RF sections: 30 MV/m - Resistive wall impedance? - Is transition gamma of ~20 a good number for the first RCS stage? - FFA alternative for RCS?
