W. Smith, U. Wisconsin, US CMS DOE/NSF Review, May, 2004 Trigger Report - 7 Installation in Underground Counting Room Expect start in June ‘05 Racks & Infrastructure installed Sufficient time for installation & some testing but not for full commissioning w/ detectors Significant time needed for integration in synchronous pipelined system Surface tests in SX5 With both HCAL and EMU Verify trigger functions & interfaces by testing w/detectors on surface at CERN. Use to reduce commissioning time as much as possible. Will check as much on surface before gaining access to underground facilities. Planned for October ‘04 - May ‘05 Tests in Electronics Integration Facility Set up central core of critical racks Underground Counting Room Trigger Installation
