Focusing Mirrors for Use with Microfocus X-ray Tubes

Several different types of X-ray mirrors suitable for use with a microfocus X-ray tube and intended principally for single-crystal diffractometry are discussed and compared. The construction and performance of ellipsoidal mirrors made by an electroforming method are described in detail. The intensity at the mirror focus is comparable with the flux obtained with conventional arrangements with X-ray tubes dissipating more than 100 times the power of the microfocus tube.
