Ion sources have wide-spread use in a multitude of applications. For many, an accurate knowledge, or better, an accurate imaging, of the beam profile and intensity is an important criterion. We are developing an ion source to calibrate instruments for space-based measurements of solar wind and suprathermal particles in the energy range from below 1 keV/nuc to above 200 keV/nuc. In order to establish accurate beam profiles for calibration purposes, we have developed a new method based on an array of very small (diameter = 0.3 mm) Faraday cups. Here, we describe the experimental setup and discuss how to achieve several requirements such as a large thermal load due to the approximately 40 W of beam power.
离子源在众多应用中有着广泛的用途。对于许多应用而言，准确了解束流轮廓和强度，或者更理想的是进行精确成像，是一个重要的标准。我们正在开发一种离子源，用于校准仪器，以对能量范围从低于1 keV/核子到高于200 keV/核子的太阳风和超热粒子进行天基测量。为了出于校准目的建立准确的束流轮廓，我们开发了一种基于非常小（直径 = 0.3毫米）法拉第杯阵列的新方法。在此，我们描述了实验装置，并讨论了如何满足诸如由于约40瓦的束流功率而产生的大热负载等若干要求。
