Page History

Please note: The system works autonomously and needs minimum attention. Scientific co-use by Desy Zeuthen. Data transfer once per day.

Neutron monitors are ground-based devices to measure the variation of cosmic ray intensities. The instrument is a counter designed to detect nucleonic components of cascades initiated by primary cosmic particles in the atmosphere.

The system consitis of two sensor units with corresponding AD electronics, a GPS time and position synchronization and a Laptop for data analysis and storage. The system is described in Krüger et al. (2003, 2008, 2010, see: Documentation).

Time synchronising is regulated via GPS.
Geographical ship's position via GPS.

Raw data (are stored on the laptop (/home/Muonic/Yearday_min.txt) and on the cards of each sensor unit.
Data volume ca 1 MB (ca 3 files) per day.

Data are archived in the institutes electronic archive and at DESY.
