  1. High Energy Cosmic Ray Physics & Neutrino Astronomy @ South Pole Experimental Program

  2. Group Members T. Gaisser, T. Stanev, S. Tilav, X. Bai P. Evenson, D. Seckel, J. Clem L. Shulman, J. Roth, A. McDermott

  3. Projects Currently working SPASE South Pole Air Shower Experiment AMANDA Antarctic Muon And Neutrino Detector Array R&D (deployment starts in 2004) IceTop km2 air shower array IceCube km3neutrino detector

  4. South Pole Air Shower Experiment @ 10000ft altitude 30 stations on area of 16,000 sq. meters 4 modules per station each module contains hexagonal scintillator of 0.2 m2 And a PMT 30m between stations Energy range of operation 1013 eV to 1016 eV

  5. SPASE stations & signals cables

  6. SPASE electronics rack SPASE counting house

  7. Amundsen-Scott South Pole Station

  8. Optical sensor Martin A. Pomerantz Observatory (MAPO)

  9. AMANDA Detector @ South Pole Antarctica • 677 OMs • on 19 strings • since Jan 2000

  10. AMANDA Neutrino Detection Principle • Neutrino interacts in ice • surrounding the detector • Muontrack is reconstructed by • mapping the Cherenkov photon • times recorded by the Optical Modules nm + N m+ X

  11. SPASE/AMANDA Coincidence Experiment • Electronic component of • air showers detected by • SPASE • Primary CR direction • and energy • Penetrating muons detected by • AMANDA • Very good tool for • Cosmic Ray mass composition • & • AMANDA calibration SPASE Skiway

  12. IceTop AMANDA • 1 station on top of each IceCube string • 2 ice tanks per station • 2 DOMs in each tank • IceTop will detect Air Showers • of energies 1014 eV to 1018 eV South Pole Skiway • 4800 PMT • Instrumented volume: 1 km3 (1Gt) • 80 Strings • IceCube is designed to detect neutrinos of all flavors at energies from 107 eV to 1020 eV 1400 m IceCube 2400 m

  13. IceCube/IceTop Digital Optical Module (DOM)

  14. IceTop Station 3.6 m3 3.6 m3 ~20m seperation 99 cm LEDs Thermosensors IceCube Hole

  15. IceTop R&D Tank2000 Tank2001

  16. IceTop R&D 2 test tanks deployed in a freezer (7F) at Port of Wilmington Nov 7 & 15 2002

  17. Our Activities • IceTop • Design of detectors • DAQ schemes • Modifications of IceCube • electronics for IceTop • MonteCarlo Simulations • Air Shower • Detector • Field work @ South Pole • We will be fully responsible • from operation, data collection • and data anaylsis • SPASE • Operation, • Maintanence • Data collection • Data analysis • MonteCarlo Simulations • Air Shower • Detector • Field work @ South Pole I • AMANDA • Analyse SPASE tagged • AMANDA data

  18. 2 Positions available - TA until Sep 2003 - RA afterwards (pending funding) Programming skills - fortran, c, c++, perl script - linux operating system Willing to travel & work at South Pole for 1 month per year
