  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 $~10^6-10^7$ Hz/$cm^2 $ 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.
