  7. Spaceweather Storms Coronal mass ejections (CME) provide hazards to the earth environment, in particular to satellites, and to power lines on ground. Reliable spaceweather forecast required. MuSTAnG

  8. Precursor Storm Signals MuSTAnG

  9. MuSTAnG • Muon Spaceweather Telescope for Anisotropies at Greifswald • Multi-directional muon telescope for spaceweather forecasting • Stage 1: 2 × 16 = 32 detectors of 0.25 m2 size each • Stage 2: Extensions to up to 2 × 36 = 72 detectors foreseen MuSTAnG

  10. MuSTAnG: phase 1 (4m2) Upper detector layer Lead layer Lower detector layer MuSTAnG

  11. upper layer lower layer Viewing directions Viewing directions are defined by the passage of a single muon through one upper and one lower detector. MuSTAnG

  12. MuSTAnG: phase 1 (4m2) MuSTAnG

  13. Asymptotic viewing directions • Location: Greifswald • 13 (of 49) Viewing directions: V, N, E, S, W • Detector size: 0.25 m2 • Rigidity spectrum: 50-150 GV MuSTAnG

  14. Detector element (4 × 0.25 = 1 m2) Detector box: • 4 scintillator plates each with • 17 wavelength-shifting fibres connected to • P30A photomultiplier modules MuSTAnG

  20. Detected muons (single) MuSTAnG

  21. Detected muons (coincident) T: 3600 s P: 25698 B: 182 S: (7.088±0.045)/s 0.63 % Upper detector-lower detector coincidences (0.0625 m2) MuSTAnG

  22. Measured statistical accuracy • 0°: 23000/h x 16 = 0.16 % • 30°: 14000/h x 12 = 0.24 % MuSTAnG

  23. Accuracy Requirement: counts/hour/direction: 1% or better MuSTAnG

  24. Integration of MuSTAnG into existing muon telscope network MuSTAnG will be part of an international muon telescope network: • Nagoya (Japan) • Hobart (Australia) • Sao Martinho (Brazil) • Bartol (USA) MuSTAnG
