The Super-Basket: Incorporation of Conical Reinforcements in the CMS ECAL EB Support Structure

This document is based on information available at the end of 2001 and summarises the main steps of an important design revision initiated at the end of 1999. Early in 2002 the design was submitted to technical reviews that validated the structural concept. With some changes affecting the material and the screwed connections clearance was given to produce a Super Basket prototype delivered in July 2002. From the assembly tests results the review committee validated the computations. Some further detail changes to the Super-Basket front connection were suggested and implemented in tests until November 2002. The committee finally gave a full approval to the design and authorised the serial production of Super-Baskets in December 2002. Technical notes accompanying the design, test and review steps since the January 2002 review will be condensed in a single document to be published in 2003.
