Advancements in Research and Development for the Auger Observatory

The Research and Development Array (RDA) was initiated to enhance technologies for the Auger Observatory, particularly in Argentina, following the improbability of Auger North. Significant investments from multiple countries led to a refocus on achieving Auger's operational goals and preparing for future enhancements. Key objectives include the development of a new communications system, advanced electronics for single PMTs, and improved structural designs for tanks and masts. Collaboration with Fermilab has been essential in design, assembly, and deployment efforts in Southeast Colorado.

  1. Research and Development for The Auger Observatory Peter O. Mazur Director’s Review December 15, 2011

  2. The Research and Development Array(RDA) • Begun to develop technologies for a possible Auger North. • When Auger North became improbable, a substantial investment had already been made by many countries. • The RDA was refocused to advance the goals of Auger in Argentina and prepare for possible future enhancements to it. • Items exclusively valuable for Auger North were dropped, e.g., development of thermal insulation systems for the water tanks.

  3. RDA Objectives • Develop a new Communications system (most important) • A new Auger Comms system is required for the new Enhancements. Although Comms refinements are in progress for the Enhancements, this could provide a backup. • Provides a capability for other, newer options. • Develop new electronics • New electronics for single PMT, with better dynamic range, faster ADC, better calibration software and hardware. • Develop new SD with a single PMT • Tank designed with a central hatch. • Tank structure needs to support a taller mast for the RDA • New PMT enclosure, better seals for reduced corrosion probability • Test new solar power system components • 12 V system • New VRLA-AGM type battery

  4. The RDA in Southeast Colorado The RDA consists of: 10 tanks 7 standalone communications masts 4 towers, including a concentrator Deployment status All SDs deployed with power system • Electronics tested on one tank • Electronics ready at Mines All masts deployed with power system All towers deployed with power system

  5. Surface Detector with three hatches for three PMTs. RDA Surface Detector For a single, central PMT

  6. RDA Surface Detector. Note extra tall communications mast.

  7. Fermilab Participation • All involved in design and planning for the RDA. • Peter Mazur and Carlos Escobar developed and procured tanks. (Made in Brazil.) • Peter Mazur (and PPD FEA engineer and drafter) designed tanks, brackets and masts, standalone masts. POM also designed solar power system. • Peter Mazur involved in assembly and deployment. • Peter Kasper adapted Auger central data acquisition system for RDA use. • Fermilab Group standing by to support RDA operations as needed.
