Tyndel 817-Dec-2002 SCT End-cap modules zBackground: uThe K4 End-cap module was found to be unstable uThe hybrid was redesigned & 16 K5 modules (outer, middle, inner) were built. They were stable and within specification pre-irradiation uThe post-irradiation performance after 3 10 14 p/cm 2 (just) meets the specification.
