Neutron and Muon Flux Measurements at BEO Moussala towards to Space Weather Research

The existing and in development devices at Basic Environmental Observatory (BEO) Moussala are presented, precisely the experiments connected with space weather and astroparticle studies. The recent results of the secondary cosmic ray measurements using atmospheric Cherenkov light telescope are presented precisely the possibility to study the atmospheric transparency. The final design of neutron flux meter based on SNM-15 detectors is described as well several preliminary experimental and Monte Carlo results. The developed muon telescope based on water Cherenkov detectors is also presented. The scientific potential is discussed, precisely the connection between cosmic ray measurements and the environmental parameters, precisely atmospheric parameters. The project for muon hodoscope and multidirectional Nor Amberd neutron monitor with the preliminary studies is shown, precisely several estimations and the possible design
