Radial Collimators |
 |
| The collimator system of the diffractometer EPSILON (location: IBR-2, JINR, Dubna, Russia) designed for residual stress measurements consists of 9 radial collimators. Each collimator is made of 48 mylar films coated with gadolinium oxide (total thickness: 50 Μm). The angular divergence of the walls of a single channel is 6 mrad. The focus of each collimator is at a distance of 200 mm from its entrance. The collimators are joined into three blocks of 3 collimators in each and are positioned on a circumference around the sample. Each collimator intercepts neutrons within an angular range ±8°. Each collimator can be mechanically adjusted to optimize the geometry of the experiment. Users |
