2. A.Levin, IHEP, Protvino, RussiaApril 27, 2010 Mechanical structure design status. 1. Preliminary design for types 1, 6, 10 and 11 of the crystal module mechanical structure is done for the normal slice. 2. Preliminary design for individual mechanical parts of crystal modules (carbon fibre alveole, aluminium inserts and intermediate plates etc.) is done. 3. Drawings for the tooling (mould) to produce alveole prototype are done. Mould was made at the beginning of 2010.
