15. What is missing  Services box design:  Responsability of Tor Vergata in parallel to chamber construction by the company  Cables and gas pipes calculation and installation  Readout and trigger electronics  Work shared between Roma1, Roma2 and Michigan  Meeting scheduled next week for DAQ integration  Now we will dedicate the necessary time to finalize the layout. Until now the priority wason the chamber 15
