Abstract

We present advancements in a finite element method for computing the physical properties of magnetic microcalorimeters (MMCs). Utilizing the COMSOL package, we conducted 3D simulations of a meander-shaped Nb coil with a realistic geometry. The resulting magnetic field distribution showed good agreement with a previous 2D simulation and revealed non-negligible differences at the side edge of the sensor material. Employing the simulation results, we calculated the MMC properties and compared them with previous measurements. Our calculated values closely align with the measured values for the sensor magnetization, the pulse heights from alpha detection, and the coil inductance.

用于稀有事件搜索实验的磁性微量热仪模拟研究

我们介绍了计算磁性微量热仪 (MMC) 物理性质的有限元方法的进展。利用 COMSOL 软件包，我们对具有逼真几何形状的蜿蜒形铌线圈进行了三维模拟。结果显示，磁场分布与之前的二维仿真结果十分吻合，并显示出传感器材料侧边存在不可忽略的差异。利用模拟结果，我们计算了 MMC 的特性，并与之前的测量结果进行了比较。我们的计算值与传感器磁化、阿尔法检测脉冲高度和线圈电感的测量值非常吻合。
