本文提出了一种新的四重分段多阳极真空光电倍增管。使用COMSOL多物理场仿真软件进行了仿真，并计算了阳极上的预测感应信号和阳极间串扰。给出了光阴极响应的空间均匀性、各部分之间的串扰和室温下的暗电流的实验数据。在14度的VPT的响应，以高达4 T的磁场被确定。
A new four-fold segmented multi-anode vacuum phototriode is presented. A simulation using the COMSOL multi-physics simulation software is described and the predicted induced signals on the anode and the inter-anode cross-talk calculated. Experimental data on the spatial uniformity of the response across the photocathode, the cross talk between segments and the dark currents at room temperature are presented. The response of the VPT at 14 degrees to a magnetic field of up to 4 T is determined.
