ALMA Project Books:

These Project Books are now all obsolete. Please see the official ALMA web pages at http://www.alma.nrao.edu/ .

ALMA Construction Project Book is here.
The original version of the ALMA Test Interferometer Project Book is available here.

MMA Project Book

  • The last ever update of the MMA Project Book (May 1999 version) is available. This is also available from the official ALMA web pages. The MMA Project Book is to be replaced by the ALMA Construction Project Book, together with the ALMA Test Interferometer Project Book.

Many of today's common-place microwave components were invented and used in the last decade of the 19th century.
