Description
The phase 1 upgrade of the CMS pixel detector will replace the existing pixel detector at
the end of 2016 in an extended technical stop. The phase 1 upgrade includes four barrel
layers and three forward disks, providing robust tracking and vertexing for LHC
luminosities up to 2.5 x 10^34 cm-2 s-1 prior to the HL-LHC era. The upgrade incorporates
new readout chips and front-end electronics for higher data rates, DC-DC powering, and
dual-phase CO2 cooling to achieve performance exceeding that of the present detector with
a lower material budget. The design of the forward detector is presented along with
present status of mechanical construction, module assembly, and module qualification. The
procedures for module testing and quality assurance are described in some detail.
