1. Solid Shielding Materials: Reyco Henning

• Will we simply provide space for experiments to stockpile their own material or will we proactively identify materials to stockpile (e.g. tungsten) which may be useful in the future?
• Small parts protected from radon plateout
• new storage techniques
• common purge cabinets and other infrastructure
• Engineering study (limited R&D) to study whether there is a cost-effective generic shield for prototypes and novel screeners, perhaps lead has become too expensive?
• Shielded space for prototypes (quick turn-around mini-experiments)

1. Liquids and Gases: Yuri

• Radon-free air
• Liquifier Plant, distribution
• define purity requirements for these substances

1. purified water: TBD
   • for water shield
   • wet lab
   • bio experiments

Engineering to identify all such applications and quantify
