Long Wavelength Demonstrator Array LWDA

Welcome to the Construction site

The LWDA is a test bed for the development of the LWA. This webpage is devoted to Progress through Photos; as the construction of the first station at the VLA develops, we will replace older photos with newer ones.
The Specmaster Data website lets you view Daily Dynamic Spectra and learn about special events from Big Blade at the LWDA site.
During second half of October 2006 all the hardware was installed at the site, including both polarizations and digital receivers for all the dipoles. Careful phase calibrations were performed and these movies demonstrate how successful they were. Congratulations to all who made this possible.

The first results are displayed in power point presentations at URSI and AAS in January 2006.
Construction of the LWDA began at the VLA site during the Autumn 2005.
