Present and future of the IRAM 30-meter millimeter telescope

 The IRAM 30-meter millimetre radio telescope is located in the Observatorio de Pico Veleta in Granada, Spain and has been continuously operating around the clock since its inauguration in 1984. It is still one of the most sensitive and powerful telescopes worldwide in its frequency range. It has been recognised as one of the facilities within the Spanish Map of Singular Scientific and Technical Infrastructures (ICTS). IRAM has embarked in an ambitious project to upgrade the 30-meter to keep it in the research leading edge in the coming years. The planned improvement actions include a new servo control system for the mount and sub-reflector, comprising hardware and software components, and upgrades in the primary reflector to improve the thermal behaviour, surface accuracy and gain-elevation curve.   The upgrade of servo system, in advanced progress state, is supported by the Spanish Instituto Geográfico Nacional (IGN) and is co-financed by European Regional Development Fund (ERDF) programme. For the improvement of the primary reflector, different options are being considered, although the most important action being assessed is in-situ re-painting the surface with a high accuracy (50 micron with a tolerance of +/-5 micron peak-to-peak). In the current scenario, all actions are scheduled for completion by the end of the Summer semester of 2023.
