Event-based hyperspectral EELS: towards nanosecond temporal resolution

Here we present the two data sets presented in the work Event-based hyperspectral EELS: towards nanosecond temporal resolution. Data was processed using Rust. In ASI Cheetah Timepix3, we have two different kinds of events: electron and TDC events (little-endian). Data chunk package is a 8-byte data that begins with "TPX3". Electron hit is a 8-byte packet that contains "0xb" in 60-63 bits. TDC data packet is a 8-byte packet that contains "0x6" in 60-63 bits. 56-59 bits identify if it is comes from TDC Line 1 or 2 and also identifies if it is a falling or a rising edge.本研究展示了刊载于论文《基于事件的高光谱电子能量损失谱（Electron Energy Loss Spectroscopy, EELS）：迈向纳秒级时间分辨率》中的两类数据集。本研究中的数据集已通过Rust语言完成处理。在ASI Cheetah Timepix3系统中，存在两类不同的事件：电子事件与时间数字转换器（Time-to-Digital Converter, TDC）事件，两类事件均采用小端字节序存储。数据块包为8字节长度的数据，其起始标识为"TPX3"。电子击中数据包为8字节长度的数据包，其60至63位的比特值为"0xb"。TDC数据包为8字节长度的数据包，其60至63位的比特值为"0x6"。该数据包的56至59位比特值可用于标识其来自TDC线路1还是线路2，同时可区分信号为下降沿还是上升沿。
