Detector Development for the Lunar Crater Radio Telescope

An ultra-long wavelength 3-30 MHz Lunar Crater Radio Telescope (LCRT) is under development at the NASA's Jet Propulsion Laboratory. The LCRT consists of a 1 km diameter reflector antenna and receiver to be deployed in the far side of the moon. The telescope will enable the observations of the early universe at the wavelengths longer than 10 m to study the cosmological signatures from the Dark Ages. Once deployed, LCRT will be the largest filled telescope in the Solar System. The 10-100 m wavelength telescope, however, presents stringent challenges and specifications to meet the Science mission of the project. The paper discusses the RF aspect of the LCRT and presents probable solutions for the detector.
