====== January 21 Agenda ======

==== Summary of Last Week's Discussion ====

  * Accept DongMing's Report - Go with 2.3 m of water thickness in shield
  * Radiopurity of Acrylic and Stainless are similar (input to thickness decision) 
  * Immersion Tank goes in far corner
    * optimal shielding
    * possible upgrade to wrap-around water shield and PMT water readout
  * Lower water shield down to tank (cost driver)
    * Top loading from above water shield (removable veto shield)
    * OR Side Loading - needs engineering concept
    * Nitrogen blanket becomes load lock mechanism either way
    * Crane is above water shield and helps with veto shield construction and transport
  * Lee will talk to Dufrane. Need a very rough cost per area coverage for water shield
  * New Drawings need to go to DUSEL by Jan 29 - in time for review by larger collaboration for Feb 4 teleconf


==== Discussion for this week ====

  * Summarize Lee and Bob's discussion wrt transfer of infrastructure into DUSEL format.
  * Summary of DuFrane discussion or beginning of a water shield cost estimate
    * Lee spoke with Lou of Dufrane earlier this week
    * January 2009 concept was:
      * 10-ft wide x 12-ft long x 9-ft high
      * 8-ft thick shielding on four sides
      * 5-ft thick shielding on top and bottom
      * Structural (carbon) steel support structure
      * Shield segments slide in and out to provide access
      * Quote was $2.785 million
    * January 2010 concept
      * Much larger internal space
      * Labyrinth access
      * Similar shielding thickness
      * Structural (carbon) steel support undesirable
    * Dufrane unwilling to provide quote or even SWAG at current level of consideration
    * Scaling calcs underway
  * Surface bldg vs Shallow site.  re: decision by DUSEL not to develop 300' or 800' areas  
  * Revisit concept drawings - what is still missing, what needs to be changed 
  * Items due in one week
    * Location of your experiment
      * for physics experiments, this means identification of either the mid-level (4850L) or deep-level (7400L) campus for installation of your experiment
    * Experiment installation drawing
      * Establish the required footprint
      * Identify all major subsystems
    * Requirements and hazard identification
      * Underground and surface spaces for fabrication, assembly, and other uses should be identified
      * Major hazards and handling and mitigation plans should be identified
