Description
The CMS central hadron calorimeters will undergo an extensive upgrade before LHC Run 3
which will occur in 2019. The upgrade is based on replacement of the current HPD with SIPMs
read out into a new ADC, the QIE11. Longitudinal segmentation of the HCAL will be increased
by about 3X depending on eta. The entire front and back end electronics will be replaced with a
3X higher bandwidth system. The new backend is based on µTCA. We report on the design and
status of SIPM development, QIE11 development, and backend system tests.
