Research and Development for The Auger Observatory Peter O. Mazur Director’s Review December 15, 2011
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.
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
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
Surface Detector with three hatches for three PMTs. RDA Surface Detector For a single, central PMT
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.
