Studies of the CMS tracker at high trigger rate

During the latter months of 2006 and the first half of 2007, the CMS\nTracker was assembled and operated at the Tracker Integration Facility\nat CERN. One of the important projects undertaken during this period was the assesment of the tracker\nat trigger rates up to 100 kHz. The test setups, outcome of the tests and subsequent consequences for operation of the Tracker are discussed.
