Dear Colleagues, This material was prepared for discussion. Your recommendation, remarks and comments are welcome. Without your participation will be impossible to provide the radioactive shielding & tooling design. I hope to have response from following people !: Wolfram Zeuner Patrick Lepeule Joseph Howell Dick Loveless Ken Bell Lino Demaria Karl Aaron Gill Gino Bolla Jean Bos Nicola Bacchetta Dmitry Druzhkin Austin Ball Nicolas Siegrist Gerard Faber Farshid Feyzi Stephane Bally Wolfgang Funk Domenico Dattola Daniel Wenman Ettore Focardi Nebojsa Smiljkovic Hubert Gerwig; Christoph Schaefer; Andrea Gaddi; Michel Arnaud Also it is necessary the responses from the sub-detectors and subsystems coordinators. 51
