Recently developed new forward lead/scintillator sampling hadron calorimeters with transverse and longitudinal segmentation will be used in the upgraded BM@N (Baryonic Matter at Nuclotron) experiment at the Nuclotron-NICA acceleration complex in JINR (Dubna). These calorimeters are very important for measurements of centrality and the reaction plane orientation in heavy-ion collisions. Digitizing the analog signals in a wide dynamic range with sampling ADC leads to the fluctuations of the measured charge. The procedure of signal processing based on the Prony least squares fit method has been developed to improve the response requiring minimum machine time. In addition, fitting the signals with a known function allows one to select effectively weak signals at the level of electronics noise, that is important for performing a calibration of calorimeter sections with cosmic muons for the BM@N experiment. The same procedure will be used for hadron calorimeter in CBM experiment at FAIR. New methods of signal processing and cosmic muon tracking for forward hadron calorimeters will be presented.

BM@N采样铅/闪烁强子量热仪的信号处理和宇宙μ子校准方法

最近开发的具有横向和纵向分段的新型前向铅/闪烁体采样强子量热仪将用于 JINR（杜布纳）的 Nuclotron-NICA 加速复合体的升级版 BM@N（Nuclotron 重子物质）实验。这些热量计对于测量重离子碰撞中的中心性和反应平面方向非常重要。使用采样 ADC 在宽动态范围内对模拟信号进行数字化会导致测量电荷的波动。已经开发了基于 Prony 最小二乘拟合方法的信号处理程序，以改进需要最少机器时间的响应。此外，用已知函数拟合信号可以有效地选择电子噪声级别的弱信号，这对于在 BM@N 实验中使用宇宙 μ 子对热量计部分进行校准非常重要。在 FAIR 的 CBM 实验中，强子量热仪将使用相同的程序。将介绍前向强子量热计的信号处理和宇宙μ子跟踪的新方法。
