Gaseous coordinate detectors and their application for biomedical studies

Wire gaseous coordinate detectors still remain a basic apparatus used at high energy accelerators, and they are being extensively introduced into related areas of science, particularly for biomedical studies. A constant evolution of these detectors makes it possible to apply their new modifications: multistep chambers, low pressure detectors, time-projection chambers and so on which enrich detector systems with new possibilities. Operational principles of these detectors and their basic parameters are given. Some examples of their application in experimental physics are described. Several features of using the wire detectors for research in molecular biology and for medical diagnostics are considered as examples of existing and being designed setups
