交叉条成像读出使用在两层正交感应条上检测到的微通道板电荷信号的电荷分割和定心,以编码事件X-Y位置和时间。我们已经开发了交叉条带探测器和完全并行的通道位置编码电子设备。前端放大器使用两个32通道前置放大器ASIC,这些ASIC将信号发送到全通道60 MHz ADC电路,然后是一个现场可编程门阵列事件处理板。使用软件有限脉冲响应过滤器和定心算法进行的测试显示,采用32 mm交叉条阳极探测器的分辨率为<10 mm,使用低微通道板增益(∼106)。自触发事件计时精度为750 ps,该系统能够在>1 MHz下结合基于固件的FPGA质心算法对光子进行编码。
The cross-strip imaging readout employs charge division, and centroiding, of microchannel plate charge signals detected on two orthogonal layers of sense strips to encode event X–Y positions and times. We have developed cross-strip detectors and fully parallel channel position encoding electronics. The front-end amplifiers utilize two 32-channel pre-amplifier ASICs that send signals to a full 64-channel 60 MHz ADC circuit followed by a FPGA event-processing board. Tests with a software Finite Impulse Response filter and centroiding algorithm demonstrate <10mm resolution with a 32mm cross-strip anode detector using low microchannel plate gain (∼106). The self-triggered event timing accuracy is 750 ps, and the system is capable of encoding photons at >1 MHz in combination with firmware-based FPGA centroiding algorithms.
