Description
In 2017 the current CMS pixel detector will be replaced with an upgraded version due to the following reasons: increased luminosity at reduced bunch spacing ( from 7 x 1033 cm-2 s-1 at 50 ns bunch spacing to 2 x 1034 cm-2 s-1 at 25 ns bunch spacing) in the LHC and radiation damage effects that will significantly degrade the present detector. The new upgraded detector will have higher efficiency and lower mass with four barrel layer and three forward/backward disks to provide higher hit pixel coverage out to pseudorapidities of ±2.5. In this talk we will give an overview on the Pixel upgrade project and expected performances, with focus on the barrel detector design and status of construction and qualification.
Summary
The talk is a presentation of the Pixel Tracker design and the production plans for the 3rd layer to be built by the italian consortium of the CMS tracker collaboration.
