Adding Interferometer Restoration and Upgrade: Learning by Doing with the NINE Program
Abstract
During the summer of 2016, participants in the National and International Non-Traditional Exchange (NINE) Program were responsible for the restoration and upgrade of N2I2, an instructional interferometer located on New Mexico Tech's Socorro campus. The NINE program is a National Radio Astronomy Observatory (NRAO) initiative geared towards providing training in project management and other STEM functional areas to underrepresented groups around the world. A description of this restoration project illustrates both the experience of a NINE program participant and, more specifically, how principles of engineering and project management were applied to achieve project objectives.N2I2 was created by a joint NRAO-New Mexico Tech (NMT) team and became operational in 2004. The original instrument comprised two ten-foot dishes which recieved signals that were added using a simple power combiner, and data was interpreted using software on computers located in a nearby control room. The theory of adding interferometry was re-discovered for the design of this unique telescope. N2I2 was built using simple hardware with the intention of allowing interested community members and students from middle school to graduate school to learn about the principles of radio astronomy.Unfortunately, between 2008 and 2016 N2I2 was not used on a regular basis and fell into disrepair. NINE program director Lory Wingate accepted the responsibility of restoring the instrument as an experiential learning opportunity for the Socorro, New Mexico NINE team.During their 9 week assignment, the NINE team created a project plan, replaced and upgraded antenna hardware, developed operation and maintenance manuals, and refurbished the control room. A project plan was created for the addition of a third antenna and that plan was successfully carried out during August and September of 2016.Ultimately, functionality was successfully restored and improved, a maintenance plan was put into place, and community interest in the instrument was reignited.
