Acquisition of X-Ray Diffractometry Equipment for Undergraduate Instruction

卡尔文学院地质、地理和环境研究系将购买飞利浦APD-3520 x射线衍射系统。多年来，x射线衍射的原理和应用训练一直是大多数本科地质学课程的重要组成部分。XRD系统的获得将使地质学专业的高年级学生受益。矿物学、光学矿物学和岩石学专业的学生将通过实践来学习XRD的基本概念和技术，并将实践诸如矿物鉴定、细胞参数表征和固溶体化学成分测定等基本应用。总体效果将大大提高对卡尔文地质学课程中结晶固体的理解。该学院将以等额的资金配合奖金。

The Department of Geology, Geography, and Environmental Studies at Calvin College will purchase a Philips APD-3520 X-ray diffraction system. Training in the principles and application of X-ray diffraction has been an important component in most undergraduate geology curricula for many years. The acquisition of an XRD system will benefit primarily upperclass majors in the geology program. Students in mineralogy, optical mineralogy, and petrology will learn through hands-on experience the basic concepts and techniques of XRD and will practice such fundamental applications as identification of minerals, characterization of cell parameters, and determination of chemical composition of solid solutions. The overall effect will be much improved understanding of crystalline solids in Calvin's geology curriculum. The college will match the award with an equal amount of funds.
