National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Detailed Summary of the Working Group on Environmental Control (T6).

DE2003804899

Publication Date	2002
Personal Author	Bialowons, W.; Laughton, C.; Seryi, A.
Page Count	18
Abstract	For the next generation of large accelerators, the civil engineering of accelerator tunnels and associated underground buildings will be a major component of the technical challenge of constructing such machines. Between a sixth and a half of the total costs of these machines must be used for the civil engineering. Because of the large physical scales of these machines the engineering will be required to be as cost-effective as possible and because the considered beam sizes are of nanometer scale, issues such as structural and thermal stability, ground motion and artificial sources of vibration in the environment will need to be carefully studied. The working group concentrated on tunneling, ground motion, stability, alignment and environmental issues.
