基于FPGA实时压缩算法的液氩时间投影室中微子探测器连续数据采集

Continuous data acquisition for liquid argon time projection chamber neutrino detectors using FPGA-based real-time compression algorithms

J. I. Crespo-Anadón

摘要:

液氩时间投影室(LArTPC)已被提议作为中微子探测器,它结合了大尺寸以最大化中微子相互作用的数量和详细记录的相互作用。以MHz采样率读出数千个通道产生具有毫米级分辨率的中微子-核相互作用的图像,从而能够识别产生的粒子,并提供多个手柄来测量它们的能量,但以牺牲大数据速率为代价。需要连续采集LArTPC数据,以便能够使用高延迟触发器来捕获非加速器射束事件。我们描述的情况下,连续读出的MicroBooNE LArTPC,授予的可能性,从超新星使用SNEWS(超新星预警系统)警报作为延迟触发获取中微子爆发。连续的数据采集是通过使用实时压缩算法(零抑制和霍夫曼压缩)实现在一个FPGA中的读出电子。

英文摘要:

Liquid argon time projection chambers (LArTPCs) have been proposed as neutrino detectors that combine both large sizes to maximize the number of neutrino interactions and detailed recording of the interaction. The readout of thousands of channels at MHz sampling rates produce images of the neutrino-nucleus interaction with millimeter-scale resolution, enabling the identification of the resulting particles and offering multiple handles to measure their energies at the expense of large data rates. Continuous acquisition of the LArTPC data is required to enable the use of high-latency triggers for capturing non-accelerator-beam events. We describe the case of the continuous readout of the MicroBooNE LArTPC, that grants the possibility of acquiring the neutrino burst from a supernova using the SNEWS (Supernova Early Warning System) alert as delayed trigger. The continuous data acquisition is accomplished by using real-time compression algorithms (zero suppression and Huffman compression) implemented in an FPGA in the readout electronics.
