Smart structure

Published: Sunday 30 June 1996

Siemens has developed a device called the Siemens Molecular Analysis Research Tool (SMART), which will substantially cut down the time taken to analyse crystal structure. The device uses a molybdenum X-ray tube to produce the X-rays which are then incident on the crystal sample. After bouncIng off from the atoms in the crystal, the radiation strikes a phosphorous screen generatingvisible light, which is gathered by a million pixel charge coupled devices (CCD). The CCD directly gives electronic data on the position and strength of the radiation, from which the structure is reconstructed.
