Abstract Scope |
In the Inertial Confinement Fusion (ICF) process, roughly a 2mm spherical shell made of high-density carbon is used as the target for laser beams, which heat it to the energy levels needed for a high fusion yield [1]. The surface quality of the shell (smooth, round, defect-free) has been identified as one of the drivers which can be controlled during the fabrication process [3]. To meet these specifications, the shells are meticulously polished, in multiple stages. The process is monitored by measuring shell surface roughness after each step, but this measurement is labor-intensive, time-consuming, and requires a human operator. To speed up this process, we propose to use Machine Learning to automatically predict surface roughness from the vibration data collected from an accelerometer connected to the polisher. Such models can generate surface roughness of the shells in real-time, allowing the operator to make changes to the polishing for optimal results. |
