This work presents updates in the diagnostics systems, magnetohydrodynamics (MHD) calculations and simulations of microwave heating scenarios of the small modular Stellarator of Costa Rica 1 (SCR-1). Similarly, the design of a flexible bolometer and magnetic diagnostics (a set of Mirnov coils, Rogowski coils and two diamagnetic loops) are introduced. Furthermore, new MHD equilibrium calculations for the plasma of the SCR-1 device were performed using the VMEC code including the poloidal cross-section of the magnetic flux surfaces at different toroidal positions, profiles of the rotational transform, magnetic well, magnetic shear and total magnetic field norm. Charged particle orbits in vacuum magnetic field were computed by the magnetic field solver BS-SOLCTRA (Vargas et al. In 27th IAEA Fusion Energy Conference (FEC 2018), 2018. IAEA). A visualization framework was implemented using Paraview (Solano-Piedra et al. In 23rd IAEA Technical Meeting on the Research Using Small Fusion Devices (23rd TM RUSFD), 2017) and compared with magnetic mapping results (Coto-Vílchez et al. In 16th Latin American Workshop on Plasma Physics (LAWPP), 2017, pp. 43–46). Additionally, simulations of microwave heating scenarios were performed by the IPF-FDMC full-wave code. These simulations calculate the conversion of the ordinary waves to extraordinary waves and allow us to identify the location where the conversion takes place. Finally, the microwave heating scenarios for the $330^{\circ }$ toroidal position are presented. The microwave heating scenarios showed that the O–X–B mode conversion is around 12–14 %. It was possible to identify the spatial zone where the conversion takes place (upper hybrid frequency).

小型模块化仿星器 SCR-1 的进展：新的诊断和加热场景

这项工作介绍了哥斯达黎加小型模块化仿星器 1 (SCR-1) 的诊断系统、磁流体动力学 (MHD) 计算和微波加热场景模拟的更新。同样，介绍了灵活的辐射热计和磁诊断（一组 Mirnov 线圈、Rogowski 线圈和两个抗磁环）的设计。此外，使用 VMEC 代码对 SCR-1 设备的等离子体进行了新的 MHD 平衡计算，包括不同环形位置的磁通量表面的极向截面、旋转变换的轮廓、磁阱、磁剪切和总磁场规范。真空磁场中的带电粒子轨道由磁场求解器 BS-SOLCTRA (Vargas等。在第 27 届 IAEA 聚变能源会议（FEC 2018），2018 年。国际原子能机构）。使用 Paraview (Solano-Piedra) 实现了一个可视化框架等。在国际原子能机构第 23 次小型聚变装置研究技术会议（第 23 次 TM RUSFD）, 2017) 并与磁测绘结果 (Coto-Vílchez等。在第 16 届拉丁美洲等离子体物理研讨会 (LAWPP)，2017 年，第 43-46 页）。此外，微波加热场景的模拟由 IPF-FDMC 全波代码执行。这些模拟计算了普通波到异常波的转换，并允许我们确定发生转换的位置。最后，微波加热场景 $330^{\circ }$ 呈现环形位置。微波加热场景显示 O-X-B 模式转换率约为 12-14%。可以识别发生转换的空间区域（上混合频率）。
