An experiment is only as good as the data acquisition system recording it. We have spent the past few years developing some fantastic experiments using nanomechanical devices for both basic physics studies, as well as working towards practical sensing applications, but we have recently become hindered by our data acquisition system. We have pushed our current electronics to their absolute limits, writing custom software to use them beyond the manufactures specifications, and are now requesting new data acquisition instrumentation that will take us to the next level. The requested state-of-the-art system is the fastest available on the market and we are ready to take full advantage of its blazing speed. This project will open up the door to study the interactions between light and matter, deemed optomechanics, which at low temperatures may help understand the crossover from the quantum realm to the classical one. And we will be able to develop our real-time explorations of how molecules interact with our nanomechanical devices, which may be useful as sensors for a variety of health and environmental needs. In addition, we will continue using our nanomechanical devices as an ultra-sensitive measurement platform for other physical phenomenon, like nanomagnetism and granular superconductivity, yet vastly improved by this system. At this moment, we have an exciting opportunity to perform ultra-high speed measurements of nanomechanical sensors for cutting edge experiments. But we have to act now to reveal the most exciting physics afforded by this top-of-the-line data acquisition system. With it, our data acquisition system will finally be as good as our experiments.

实验的好坏取决于数据采集系统的记录。在过去的几年里，我们使用纳米机械设备开发了一些奇妙的实验，既用于基础物理研究，也用于实际的传感应用，但我们最近受到了数据采集系统的阻碍。 我们已经将当前的电子设备推向了绝对极限，编写了定制软件以使用超出制造商规格的产品，现在正在要求新的数据采集仪器，这将使我们更上一层楼。 所要求的最先进的系统是市场上最快的，我们准备充分利用其惊人的速度。 该项目将打开研究光与物质之间相互作用的大门，被认为是光力学，在低温下可能有助于理解从量子领域到经典领域的交叉。 我们将能够开发我们的实时探索分子如何与我们的纳米机械设备相互作用，这可能是有用的传感器为各种健康和环境的需求。 此外，我们将继续使用我们的纳米机械设备作为其他物理现象的超灵敏测量平台，如纳米磁性和颗粒超导性，但通过该系统得到了极大的改进。 目前，我们有一个令人兴奋的机会，可以对尖端实验中的纳米机械传感器进行超高速测量。 但我们现在必须采取行动，揭示这个顶级数据采集系统提供的最令人兴奋的物理学。 有了它，我们的数据采集系统最终将和我们的实验一样好。
