As there likely won't be an opportunity to properly document the design of the beam dump insert and cooled lead shielding in design notes, a list of design reviews, released on Docushare is provided below.  These provide a reasonable overview of the design process for each item.  In addition the attached PDF of scanned notes provides detailed information on the lead shielding design.  Further notes, ANSYS documents, meeting minutes, concept reviews, etc, can be be found on Isaac Earle's hard drive.  Released drawings for each completed design are available on the PDM Works Vault.
