In planning for the Phase II upgrades of CMS and ATLAS major considerations are: 1)being able to deal with degradation of tracking and calorimetry up to the radiation doses to be expected with an integrated luminosity of 3000 fb-1 and 2)maintaining physics performance at a pileup level of ~140. Here I report on work started within the context of the CMS Forward Calorimetry Task Force and continuing in an expanded CERN RD52 R&D program integrating timing (i.e. measuring the time-of-arrival of physics objects) as a potential tool for pileup mitigation and ideas for Forward Calorimetry. For the past 4 years our group has focused on precision timing at the level of 10-20 picoseconds in an environment with rates of ~106-107 Hz/cm2 as is appropriate for the future running of the LHC (HL-LHC era). A time resolution of 10-20 picoseconds is one of the few clear criteria for pileup mitigation at the LHC, since the interaction time of a bunch crossing has an rms of 170 picosec. While work on charged particle timing in other contexts (i.e. ALICE R&D) is starting to approach this precision, there have been essentially no technologies that can sustain performance at these rates. I will present results on a tracker we developed within the DOE Advanced Detector R&D program which is now meeting these requirements. I will also review some results from Calorimeter Projects developed within our group (PHENIX EMCAL and ATLAS ZDC) which achieved calorimeter timing precision< 100 picoseconds.
