The case for measuring the time
of arrival of physics objects in the major LHC Experiments (CMS\, ATLAS a
nd TOTEM so far) has been building since it was first proposed roughly 5 y
ears ago [?] and the LHC committee has already approved (in March 2018) fo
r CMS to proceed to the next stage- the technical design. Along with this
process there have been separately intense activities in establishing the
physics performance benefits (through simulations) of this enhanced capabi
lity as well as laboratory and particle beam work to establish candidate t
echnologies for the required level of timing precision (roughly 20-30 pico
second time resolution). A significant base for this sensor \; develop
ment work has been within the &ldquo\;PICOSEC&rdquo\; collaboration\, whic
h is not part of an LHC experiment but rather evolved within 2 CERN R&\
;D groups following a &ldquo\;common fund proposal&rdquo\; by S. White and
I. Giomataris in 2014. Over the past 3 years this project has accumulated
a very carefully curated data set of high quality ( 2- 5 GHz BW and 20-40
GSa/s sampling) waveforms for the principal detector technologies (Silico
n with internal Gain\, MicroPattern Gas structures\, Micro Channel Plate P
MT) and achieved world records in timing precision for all of these sensor
types. We propose to build from the productive collaboration with Wolfram
Research during 2017 to use this large data set to guide the design of si
gnal processing and digitizing electronics for fast timing\, which is now
capturing the attention of electronics groups in the US and Europe.
