Creation of an Ultra-Fast Charge Division Imaging Detector

小行星9405098 电荷分裂探测器形成了用于低强度电子、离子或光子束的定量成像的一类重要的探测器。 一个常见的例子是电阻阳极编码器（RAE），通常用于在二次离子质谱（西姆斯）中创建成分图像。 目前RAD型探测器的一个显著缺点是它们有限的最大计数率。 该研究项目提出通过使用新的电子脉冲处理方法和新的互连方案来显着提高这些检测器的速度，以将其脉冲计数死区时间减少十倍。 第一阶段的研究表明，有可能整合脉冲，并对相隔仅30 ns的脉冲进行必要的处理。 第二阶段的研究将研究如何将快速脉冲处理设计纳入一个功能性的RAE探测器中，包括分析脉冲传播和电压隔离连接上的振铃。 通过将所有东西放在一起，这项研究的产品将是一个功能强大的超快位置敏感探测器原型，然后可以在第三阶段进行改进和商业化。 ***

9405098 Colvard Charge division detectors form am important class of detectors for quantitative imaging of low-intensity electron, ion, or photon beams. A common example is the resistive anode encoder (RAE), commonly used to create composition images in secondary-ion mass spectrometry (SIMS). A significant drawback of present RAD-type detectors is their limited maximun counting rate. This research project proposes to significantly increase the speed of these detectors by using a new electronic pulse processing approach and a novel interconnection scheme to reduce their pulse-counting dead time by a factor of ten. A Phase I study showed that it is possible to integrate the pulses and perform the necessary processing on pulses separated by as little as 30 ns. this Phase II research will study the incorporation of the fast pulse processing design into a functioning RAE detector, including the analysis of pulse propagation and ringing across voltage isolating connections. By pulling everything together, the product of this research will be a functioning prototype ultrafast position sensitive detector that can then be refined and commercialized in Phase III. ***
