###### Abstract  
Detectors with cross strip (XS) anodes have high application value in deep space exploration, quantum communications, space astronomical telescopes, etc. In this article, a single-layer XS anode based on Printed Circuit Board (PCB) technology is proposed, which can conveniently realize large-area array detection with a simple process and low cost. We theoretically studied the electron motion principle and equivalent model of the XS anode and established a model of the XS anode through the finite element method. The model allows us to determine the anode geometry, such as anode strip width, inter-strip distance, and substrate thickness, to optimize the output signal on the XS anode, thereby indirectly affecting the resolution of the detector. The optimal parameters of the detector were processed with the help of our model, such as a strip width of 110 \(\upmu\)m, strip spacing of 550 \(\upmu\)m, and substrate thickness of 150 \(\upmu\)m. The model shows that the strip charge collection ratio is 1:1. Comparing model predictions with experimental measurements reveals key parameters, such as the manufacturing is convenient and simple and can provide some ideas for subsequent large-area array detector imaging.

Moreover, the splicing method is complicated with multiple square anodes. Berkeley Lab uses high-temperature co-fired ceramics to process anodes [16], but the temperature of high-temperature co-fired calcination is above 1500\({}^{\circ}\) and the processing method is relatively complicated. At present, the application demand for large-area arrays is relatively high [13; 17]. Therefore, we proposed a single-layer XS anode processed using Printed Circuit Board (PCB) technology, which can reduce costs and achieve large-area array detection. Moreover, we study the output of the electron cloud from the MCP to the final signal collected by the anode plate. The quality of the signal will affect the quality of the final resolution. XS anode imaging detectors often require optimization of the event charge footprint for high spatial resolution and good image linearity [18]. In order to achieve better detector performance indicators, the electron cloud footprint characteristics can be optimized by changing the geometry and specific parameters of the XS anode. At the same time, we need to consider that the single layer anode will bring inevitable crosstalk [19; 20; 21]. Crosstalk is caused by inter-strip capacitance, which affects the charge collection of the strips, adding a certain degree of noise to the output signal. Impulse noise in the anode output signal is added to the electronic readout system, indirectly affecting spatial resolution. The accuracy of the pulse value of the anode output signal enables more precise localization of events and also prevents the pulse signal from being masked by noise from the strip. Therefore, it is necessary to conduct theoretical and simulation research on the parameter design of the XS anode and analyze the parameters of the XS anode based on simulation. This article mainly proposes a single-layer XS anode using PCB technology and analyzes and optimizes its parameters. Section 2 introduces the working principle of the XS anode detector. Through theoretical research, the movement principle of electrons on the metal strips, the equivalent model of the interaction between the charge cloud and the XS anode, and the capacitance between the XS anode strips are given.
