Future WIMP dark matter Criteria Scientifically interesting does it have reach to new parameter space or can it better understand a discovered particle? Can Fermilab play a leading role? Size does it need to be big? What is the right scale? Four possibilities I m not ready to choose Large liquid noble detector Upgrade to LZ PICO-X Liquid helium detector 1 9/29/2024 Presenter | Presentation Title or Meeting Title
Large future liquid noble detector (LXe or LAr) Probe down to neutrino floor (what does that mean?) at 100 GeV (x5-10 relative to LZ plan) At the moment, no real momentum in US, so FNAL could start the US train Cryogenics is an obvious in, between LZ and DS work. Politics are tricky for LAr, FNAL/SLAC/LBL in LZ already Definitely big enough ($100M) 2 9/29/2024 Presenter | Presentation Title or Meeting Title
Upgrade to LZ Doping with Helium (Hugh s EC proposal), Double beta decay, or extended running with additional background reduction (e.g. radon removal) He-doping has new reach (in 2025?), extended running can get another factor of 2-3 He-doping would be FNAL led by default, Hugh currently co-chair of future LZ task force Maybe not big enough?

PICO-G3 If LZ/XENONnT see nothing, and one wants to continue at the >~100 GeV mass scale, bubble chambers are a good (the only?) candidate The Further Future - PICO 500 FNAL has abandoned leadership for now Could we get it back without a change at DOE? Probably is big enough if FNAL grabs a significant piece 18 UCLA DM 2018 4 9/29/2024 Presenter | Presentation Title or Meeting Title
Liquid Helium Detector Push to low masses, beyond any other current technology Cryogenic or calibrations role for FNAL, ties in with quantum sensing perhaps Politics are interesting McKinsey at LBL, but not clear that they are pushing it at the lab Very R&D-y at the moment in 5 years, would we be ready to do something for real? 5 9/29/2024 Presenter | Presentation Title or Meeting Title
Future WIMP dark matter Four possibilities I m not ready to choose Large liquid noble detector probably makes the most sense from the lab perspective, but I don t think anyone is that jazzed about it Upgrade to LZ probably contingent on my early career, likely not big enough to employ >~5 people PICO-X ties into Eric s bubble chamber LDRD, in the heyday, COUPP did employ 5 people, and could again, but political headwinds getting going right now Liquid helium detector possible tie into quantum information, but least current expertise at FNAL we would need someone to actually think about this with real fraction of time 6 9/29/2024 Presenter | Presentation Title or Meeting Title
