Description
The High Luminosity extension of the LHC program (HL-LHC) will impose in an order of magnitude larger radiation levels and pile-up conditions in CMS. To cope with the challenges, the endcap calorimeter of CMS will be replaced with a highly granular imaging calorimeter (HGCal). It will use about 6 million silicon diode based channels of 0.5-1 cm$^2$ size and about four hundred thousand scintillator tiles read-out directly by silicon photomultipliers. In addition to measuring the energy and position of energy deposits, the time of arrival will be measured with a precision of 50ps to separate interactions within the same bunch crossing. We will present the main design concepts of the detector, the status of the project and the future plans.
