6 Rainer HipplerMuSTAnG6 Wendelstein-7-X Greifswald Large Stellarator for Fusion Research

7 Rainer HipplerMuSTAnG7 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.

8 Rainer HipplerMuSTAnG8 Precursor Storm Signals

9 Rainer HipplerMuSTAnG9 Muon Spaceweather Telescope for Anisotropies at Greifswald Multi-directional muon telescope for spaceweather forecasting Stage 1: 2 × 16 = 32 detectors of 0.25 m 2 size each Stage 2: Extensions to up to 2 × 36 = 72 detectors foreseen

10 Rainer HipplerMuSTAnG10 MuSTAnG: phase 1 (4m 2 ) Upper detector layer Lead layer Lower detector layer

11 Rainer HipplerMuSTAnG11 Viewing directions Viewing directions are defined by the passage of a single muon through one upper and one lower detector. upper layer lower layer

12 Rainer HipplerMuSTAnG12 MuSTAnG: phase 1 (4m 2 )

13 Rainer HipplerMuSTAnG13 Asymptotic viewing directions Location: Greifswald 13 (of 49) Viewing directions: V, N, E, S, W Detector size: 0.25 m 2 Rigidity spectrum: 50-150 GV

14 Rainer HipplerMuSTAnG14 Detector element (4 × 0.25 = 1 m 2 ) Detector box: 4 scintillator plates each with 17 wavelength-shifting fibres connected to P30A photomultiplier modules

15 Rainer HipplerMuSTAnG15 Scintillator/WLS fibre/PMT

16 Rainer HipplerMuSTAnG16 P30A module

17 Rainer HipplerMuSTAnG17 MuSTAnG Detector boxes

18 Rainer HipplerMuSTAnG18 Scintillator

19 Rainer HipplerMuSTAnG19 Scintillator plates with wavelength-shifting fibres

20 Rainer HipplerMuSTAnG20 Detected muons (single)

21 Rainer HipplerMuSTAnG21 Detected muons (coincident) Upper detector-lower detector coincidences (0.0625 m 2 ) T: 3600 s P: 25698 B: 182 S: (7.088±0.045)/s 0.63 %

22 Rainer HipplerMuSTAnG22 Measured statistical accuracy 0°: 23000/h x 16 = 0.16 % 30°: 14000/h x 12 = 0.24 %

23 Rainer HipplerMuSTAnG23 Accuracy Requirement: counts/hour/direction: 1% or better 

24 Rainer HipplerMuSTAnG24 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)
