Particle Induced X-ray Emission (PIXE) spectroscopy, an ion-beam analysis technique, is a powerful tool for studying the environment. The Union College Ion-Beam Analysis Laboratory (UC -IBAL) provides a small group of students opportunities to explore experimental physics and complement their classroom training, by studying atmospheric aerosols and liquid precipitation from upstate New York using a tandem electrostatic particle accelerator. The students learn how to operate the accelerator and gain valuable laboratory skills in sample collection and preparation procedures and data acquisition and analysis techniques, as well as presentation skills.
