The Rigaku D/max Diffractometer is used to accurately measure the xray diffraction pattern of a sample. The xrays are produced with a tube (on the left in the picture), pass through a sample on a glass plate, and the detector (on the right) moves in a semicircle (front to back). The D/max is completely controlled by a computer to achieve better precision. The xray tube is water cooled to keep from melting the metal target which produces the xrays. The D/max was assembled by Dr. Stephen Yerian while on sabbatical in 1998.
