Project Charter

Observations in the K-band frequency spectrum (18-26.5 GHz) of extended sources in the spectral line require inordinate amounts of telescope time with a single pixel receiver. Focal-plane array instruments improve telescope efficiency with additional sampling of the aperture plane. A seven beam K-band instrument will be developed that improves mapping speed and map calibration for extended molecular regions, and provides a costing model for future focal-plane array projects. The funding of the project is through Lockheed Martin funds which includes a contingency for beginning work on spectrometer development and data transmission, or for funding personnel in case of schedule slippages.

Project Deliverables

  • A dual circular polarized seven beam K-band receiver with up to 1.8 GHz of instantaneous bandwidth.
  • Software for monitor and control, configuration support, and data analysis.
  • A documented design and costing model per pixel for expansion of the instrument.

Project Scope

In three years an instrument for improved spectral line mapping at K-band is delivered. Although the feeds are uncooled, all components preceding and including the HEMT amplifiers are cooled providing low system temperature for efficient mapping. Calibration is by a cooled noise injection module. A tunable downconverter multiplexes two fixed polarizations onto a single channel compatible with the existing GBT IF system and spectrometer. A data analysis package will aid in instrument commissioning and provide methods for generating maps from the collected data.

Outside the scope are:
  • A new spectrometer and data transmission system.
  • An efficient and extensive data reduction package.
  • Increased data storage and archiving capabilities.

Communications Plan

  • A monthly meeting with team members.
  • Weekly progress at Friday Commissioning Meetings.
  • Conceptual Design Review to finalize the design (~1/08).
  • Critical Design Review for single pixel results disclosure (~08/08).
  • Periodic reports to Users Committee.
  • Monthly updates sent to email list.
  • NRAO newsletters updates.
  • NRAO-GB instrumentation brochures status report.
  • Poster presentations or talks at SPIE, or other similar conferences.
