Brick components vs Responsible Institutes Review of brick component dimensions & tolerances Main steps to make a brick, dimensions & tolerances Final brick 3D sizes Wall dimensions October 2002, LNFOPERA Collaboration Meeting

2 What do we call a “brick” ? On last October 1 st and 2 nd the present working group had a meeting at CERN. The goal was to evaluate in all details the brick components and the procedure of brick manufacturing. The result was summarized in a document circulated to the OPERA Collaboration on last October 18 th. In order to fit with the present OPERA schedule we need to endorse this document in the present meeting.
