PV is devoted to chamber test only and to bakelite QC; An additional external company (HT) will be involved in the assembly (under the control of NA group); Gap production and quality control remains mainly with the BA group with some help from the NA group; Chamber assembly at GT remains with the BA group only; BA remains as chamber test site and an assembly sites for RB3 chambers in the first phase. Assumptions for phase I (end 2003/start 2004) SO becomes an assembly and test site for RB3 in the phase 2; BA site can be considered as back site for RB3 assembly in case of difficulties; RB1 chambers are built in Italy (GT) and tested at PV A way to involve physicists from PU in the RB1 test should be envisaged; RB2 are built at HT and tested at BA.
