原子、分子和光学物理实验的柔性控制系统

A flexible control system for atomic, molecular and optical physics experiments

Andreas Trenkwalder, Matteo Zaccanti, Nicola Poli

摘要:

我们已经实现了一个控制系统,在原子,分子和光学物理实验的基础上的商业低成本的板,具有现场可编程门阵列的一部分,系统上的一个片上运行的Linux操作系统。该板具有千兆以太网,允许快速数据传输和远程实验系统的操作。一个单板可以控制一组器件,这些器件产生数字、模拟和射频信号,并具有由外部或内部时钟给出的精确定时。连续输出和输入采样率可达40 MHz。多个板可以同步运行,定时误差接近1 ns。为此目的,一种新的自动同步方案证明,在复杂的分布式实验设置与苛刻的时序要求的可能应用。

英文摘要:

We have implemented a control system for experiments in atomic, molecular and optical physics based on a commercial low-cost board, featuring a field-programmable gate array as part of a system-on-a-chip on which a Linux operating system is running. The board features Gigabit Ethernet, allowing for fast data transmission and operation of remote experimental systems. A single board can control a set of devices generating digital, analog and radio frequency signals with a precise timing given either by an external or internal clock. Contiguous output and input sampling rates of up to 40 MHz are achievable. Several boards can run synchronously with a timing error approaching 1 ns. For this purpose, a novel auto-synchronization scheme is demonstrated, with possible application in complex distributed experimental setups with demanding timing requests.
