Results of a prototype imaging system using the FGLD technology and self-triggering discharge-protected readout electronics

Previous work on the FGLD (Field Gradient Lattice Detector) involved reading out 50 strips from the detector using the GP5 chip: a 128-channel charge-sensitive preamplifier with integrated individually programmable trigger. The work showed that the GP5 was suitable as a front-end electronics, but demonstrated the need to protect the inputs from discharges. To that end, the 128-channel diode protection chip developed for the TOTEM experiment has been successfully adapted to the GP5 and shown to make the GP5 resilient to destruction upon discharge. Armed with this robust front-end electronics and the FGLD technology, the group is developing a prototype imaging system capable of producing images relevant for medical and industrial applications. A discussion of the system's parameters and performance will be presented along with some images made with a collimated source.

先前关于场梯度晶格探测器（FGLD）的工作涉及使用GP5芯片从探测器读出50条带：这是一种具有集成的可单独编程触发功能的128通道电荷灵敏前置放大器。这项工作表明GP5适合作为前端电子设备，但也证明了需要保护输入免受放电影响。为此，为TOTEM实验开发的128通道二极管保护芯片已成功适配于GP5，并证明能使GP5在放电时免遭损坏。有了这种强大的前端电子设备和FGLD技术，该团队正在开发一种原型成像系统，能够生成与医疗和工业应用相关的图像。将结合使用准直源生成的一些图像，对系统的参数和性能进行讨论。
