The SCR-1 is a small modular stellarator designed, constructed and is being implemented at Instituto Tecnológico de Costa Rica. The project is its final phase of commissioning and it is expected to be operational in June 2015. This article aims at summarizing the SCR-1 project from the engineering and manufacturing point of view, particularly highlighting the construction of the toroidal vacuum vessel and the modular coils.

The Large Helical Device (LHD) is one of the world’s largest superconducting helical system fusion-experiment devices. Since the start of experiments in 1998, it has expanded its parameter regime. It has also demonstrated world-leading steady-state operation. Based on this progress, the LHD has moved on to the advanced research phase, that is, deuterium experiment, which started in March 2017. During the first deuterium experiment campaign, an ion temperature of 10 keV was achieved. This was a milestone in helical systems research: demonstrating one of the conditions for fusion. All of this progress and increased understanding have provided the basis for designing an LHD-type steady-state helical fusion reactor. Moreover, LHD plasmas have been utilized not only for fusion research, but also for diagnostics development and applications in wide-ranging plasma research. A few examples of such contributions of LHD plasmas (spectroscopic study and the development of a new type of interferometer) are introduced in this paper.

El <em>stellarator</em> de Costa Rica 1, llamado SCR-1, es un dispositivo de confinamiento magnético de plasmas de alta temperatura, diseñado, construido y en fase de implementación en el Instituto Tecnológico de Costa Rica. Durante su operación el plasma será confinado por el campo magnético (~43,8 mT) de 12 bobinas modulares, con seis vueltas de cable de cobre AWG#4 por bobina, y alimentadas por un banco industrial de baterías (150 A-h, 120 V), que debe suministrar en forma constante 767,8 A por un periodo de 4 s a 10 s. El cambio de la resistencia eléctrica por el calentamiento óhmico en el cable conductor de las bobinas planteó la necesidad de diseñar, construir e implementar un regulador de corriente eléctrica que suministrara en forma constante 767,8 A por el periodo de tiempo indicado. Este artículo presenta el diseño de un circuito de potencia eficiente y de bajo costo, para regular la corriente eléctrica en las bobinas modulares del SCR-1, así como el diseño de un control digital PID con algoritmo de velocidad, que permite disminuir la magnitud de los armónicos para no generar errores en el campo magnético del <em>stellarator</em>.
