ORCA, from the Spanish name Observatorio de Rayos Cósmicos Antártico, is a cosmic ray detector devoted to the observation of secondary cosmic rays at Juan Carlos I Spanish Antarctic Base (62° 39′ 46′′S,60° 23′ 20′′W, 12 m above sea level). ORCA was installed at the beginning of January 2019 after performing a latitudinal survey from Vigo (Spain) to...

This article presents the design and implementation of a new data acquisition system to be used as replacement for the old ones that have been in use with neutron monitors for the last decades and, which are eventually becoming obsolete. This new system is also intended to be used in new installations, enabling these scientific instruments to use t...

In this work, non-recurrent Forbush decreases (FDs) triggered by the passage of shock-driven interplanetary coronal mass ejections (ICMEs) have been analyzed. Fifty-nine ICMEs have been studied but only the 25% of them were associated to a FD. We find that shock-driving magnetic clouds (MCs) produce deeper FDs than shock-driving ejecta. This fact c...

The cosmic ray component in the range of energies below 15 GeV is strongly affected by transient phenomena related to solar activity. Cosmic rays and solar particles with energies between 0.5 and 15 GeV can be observed by neutron monitors at ground level. In absence of solar activity, the background counting rate registered by neutron monitors is d...

This work shows the present status of the Castilla-La Mancha Neutron Monitor (CaLMa). Thanks to the founds recently agree for the Castilla-La Mancha Comunity governement. The new neutron monitor station will be building and placed in the Alcalá University campus in Guadalajara. Being operative in a provisional site at the end of 2010. The station i...

The two twin spacecrafts, HELIOS A and HELIOS B, explored the inner heliosphere from about 0.29 AU to 1 AU in the 1970's. Onboard the spacecraft in-situ instruments measured among others the solar wind, the heliospheric magnetic field and energetic particles. These data can ideally be used for planning future missions toward the Sun as e.g. Solar O...

This work shows the present status of the Castilla-La Mancha Neutron Monitor (CaLMa). Thanks to the founds recently granted by the Castilla-La Mancha Community government. The new neutron monitor station will be building and placed at the Alcalé University campus a in Guadalajara (Spain). Guadalajara is located near center of Spain on the 7 GV vert...

To develop on-board software in embedded space applications, it is often a requirement to use a real-time operating system, since these systems must assure that the timing constraints associated to each task are guaranteed. Furthermore, it's desirable that the execution time of the real-time application in any scenario is as deterministic as possib...

Intensive use of information technologies has produced the need of managing important amounts of information in digital format. Depending on particular circumstances, the information may be stored in single documents, data bases, web pages or in document management systems what may lead a potential source of interoperatibility problems. In this pap...

Semantic representation of information has some evident advantages from an integra- tion point of view, but there are many situations in which this approach is not directly applicable, as information is stored in several formats without (implicit or explicit) knowl- edge of its semantics. We present a distributed middleware able to unify the access...

This article describes the implementation of an obstacle detector system based on laser technology (laser pointer) and the associated electronics used for correct and adequate operation. This system is part of a mobile robot that is able to move itself autonomously around an environment where light-colored obstacles are located. The obstacle detect...

The Real time database for high-resolution neutron monitor measurements(NMDB), which was supported by the 7th Framework Programme of the European Commission, hosts data on cosmic rays in the GeV range from European and some non-European neutron monitor stations. Besides real-time data and historical data over several decades in a unified format, it...

Resumen: Un monitor de neutrones está formado por un conjunto de contadores proporcionales cuyo principio activo es un gas capaz de interaccionar con neutrones térmicos y producir unos productos con energía suficiente para ionizar dicho gas. Los gases más empleados son trifloruro de boro (10 BF3) y helio 3 (3 He). Existen dos tipos estándar de moni...
