Abstract
The Atacama Large Millimeter Array (ALMA) is a large Fourier synthesis imaging telescope designed to operate at millimeter and sub-millimeter wavelengths, a wavelength regime that remains, thus far, largely unexplored. Yet this important wavelength range offers a number of unique and important diagnostics of astrophysical processes. ALMA is a general purpose instrument designed to address an extremely broad science program, including cosmology; formation of clusters, galaxies, stars, and planets; synthesis of the elements; and low temperature thermal science. ALMA is also designed to support solar observing in order to address outstanding issues in solar physics. After reviewing ALMA's instrument specifications, the problem of solar observing in the mm/submm-λ band is discussed. The relevant emission mechanisms on the Sun are introduced and several examples of previous observations in the mm/submm-λ range are presented. The use of ALMA for solar observing is then considered.
