Creep test results on D0 RunIIB stave

[摘要] The D0 RunIIb final design stave has been tested to verify its response to long term loading (creep). Two stave mockups have been investigated. Mechanical stave No.3 has been under continuous loading for 8 weeks. The maximum deflection was 3.6 {micro}m, with 80% of the total sag reached after the first two weeks. Mechanical stave No.2, despite the denomination, has been assembled successively with improved gluing assembly process and tested for six weeks. No creep mechanism has been observed in this surveyed mockup.
