Links on this page will allow you to view or download drawings associated with the G0 cryogenic target and its various subsystems. Drawings have been stored in a number of formats. Generally, drawing files (.dxf and .dwg) are compatible with Autocad release 12. .dxf files may (or may not) be compatible with other CAD programs.
In some cases, groups of drawings have been archived as a single file either with the Unix utility tar. The files have been compressed Gnu zip. Your browser may automatically unzip them and then try to display them on your terminal. While this may work for some formats for which you have installed helper programs, others may be displayed as (unreadable) text. In that case, try downloading the file using FTP from the G0 FTP site at ftp://ftp.npl.uiuc.edu/pub/G0/drawings/target/.
