Abstract

The near-Earth cosmic ray flux has been monitored for more than 70 years by a network of ground-based neutron monitors (NMs). With the ever-increasing importance of quantifying the radiation risk and effects of cosmic rays for, e.g., air and space-travel, it is essential to continue operating the existing NM stations, while expanding this crucial network. In this paper, we discuss a smaller and cost-effective version of the traditional NM, the mini-NM. These monitors can be deployed with ease, even to extremely remote locations, where they operate in a semi-autonomous fashion. We believe that the mini-NM, therefore, offers the opportunity to increase the sensitivity and expand the coverage of the existing NM network, making this network more suitable to near-real-time monitoring for space weather applications. In this paper, we present the technical details of the mini-NM’s design and operation, and present a summary of the initial tests and science results.

Funding: Operation of DOMC/DOMB mini-NMs is supported by projects CRIPA and CRIPA-X (No. 304435) of the Academy of Finland, Finnish Antarctic Research Program (FINNARP). DOMC/B NM data can be obtained from http://cosmicrays.oulu.fi, courtesy of the Sodankylä Geophysical Observatory. Operation of DOMB/DOMC NMs are possible thanks to the hospitality of the Italian polar programme PNRA (via the LTCPAA PNRA 2015/AC3 project) and the French polar Institute IPEV. The neutron monitor database NMDB (http://nmdb.eu) founded under the European Union’s FP7 programme (contract no. 213007) is acknowledged for hosting and providing data. We acknowledge support from the MINECO – FPI 2017 program, co-financed by the European Social Fund. This work has been supported by the project CTM2016-77325-C2-1-P, funded by Ministerio de Economía y Competitividad, and by the European Regional Development Fund, FEDER.
