Experimental Advanced Superconducting Tokamak (EAST) employs Extreme Ultraviolet (EUV) spectroscopic diagnostic systems to measure the impurity radiation of the core plasma. However, the sensor chip is significantly affected by the interference from hard X-rays on, resulting in a significant amount of single-pixel noise in the collected spectral image data. This interference presents significant challenges for accurately analyzing the impurity radiation in fusion plasma. To address this issue, hardware algorithms are prepared to be integrated into the detector to optimize the imaging quality. However, since the existing commercial detector could not be modified in terms of hardware and programming, decision to develop an imaging system for EUV spectral diagnosis. This imaging system will be used on EAST for EUV spectral diagnosis and for future research on hardware optimization algorithms. The imaging system is designed with the GSENSE400BSI sensor chip as the photosensitive component and the AC7Z100B board as the control center, and it also includes two high-speed transmission interfaces: USB 3.0 and Camera Link. Finally, to verify the acquisition function and imaging quality of the imaging system, tests were conducted on the established spectral image acquisition platform. The results showed that the imaging system could normally complete the spectral image acquisition with high- quality imaging. |
from a scientific perspective, it will be harder. it is simply a fact that even with comparable atomic absorption cross section, Sn is a solid, and Xe is a gas. That means atomic density of the Sn target is on the order of 1000x higher.
Yeah I strongly suspected molar density for Xenon was going to be an issue. *That said* the patent which brought up this discussion seems to use a magnetic pinch to help with conversion efficiency and I am extremely curious how effective that method is.
