摘要
MPD实验的大型电磁量热计(ECal)正在NICA综合体中开发,用于精确测量光子和电子的空间和能量参数。为了提高信号测量的精度,使用两个函数逼近ADC64ECal模数转换器波形:也用于BM@N实验的Novosibirsk函数,以及通过快速ESPRIT (Estimation of signal parameters via Rotational Invariance Techniques)方法计算参数的三个指数之和。我们使用R2准则和低能域的能量分辨率比较了这两个函数的近似精度。
Digital Signal Processing Models for the ECAL of the MPD/NICA Experiment
The large-scale electromagnetic calorimeter (ECal) of the MPD experiment is being developed in the NICA complex to precisely measure spatial and energy parameters for photons and electrons. To increase the accuracy of signal measurements, the ADC64ECal analog-to-digital converter waveforms were approximated using two functions: the Novosibirsk function, also used in the BM@N experiment, and the sum of three exponents having parameters calculated through fast ESPRIT (Estimation of Signal Parameters via Rotational Invariance Techniques) method. We compare the approximation accuracy for the two functions using the R2 criterion and energy resolution in the low-energy domain.
期刊介绍:
The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
