[22.06] A Small Radio Telescope Interferometer at MIT Haystack Observatory

P. Pratap, J. A. Ball, A. E. E. Rogers (MIT Haystack Observatory)

The Small Radio Telescope (SRT) was developed at Haystack Observatory with support from the NSF. The telescope consists of a 7.5-m antenna with a 1.4-GHz receiver system. It is available as a low-cost kit through Cassi Corp. (http://www.cassicorp.com/). We describe a project to develop a simple adding interferometer with two SRTs some 55 m apart. We describe the technique used and the hardware needed to reproduce our experiment. Interferometer fringes from the Sun were compared with a simple model.

The SRT was developed as an educational tool to introduce radio astronomy and radio-astronomical observing techniques mainly at the undergraduate level. Supporting materials, such as an introductory radio-astronomy tutorial and a description of the SRT components and projects, were developed and are available on the Haystack Observatory web site(http://www.haystack.mit.edu/). This interferometer project provides the next step and introduces concepts of radio interferometry to interested students and faculty. A detailed description of the building of the interferometer will soon be available on the Haystack web site.
