This is an old revision of the document!
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
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
Prisca gone next week - Lee leads teleconference
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
Experiment installation drawing
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
