Abstract: A drift tube construction includes a thin wall aluminum tube with a thin wire at its center attached to a terminal. The tube is plugged at both ends. The terminal is embedded at the center of the plug with material insulating it from Drift tube main body. The Drift tube assembly is sealed and filled with a gas mixture. A voltage is applied to the thin wire via the terminal. Current drift tubes employ plastic material to insulate the terminal from Drift tube main body and O-rings to provide a near hermetic seal.

Abstract: A detector unit for two-dimensional detection of incoming radiation from an X-ray source, primarily for use in X-ray radiography. The unit includes a solid material structure (2) having a plurality of passages (6) extending therein and comprising surface portions (7) comprising a conversion medium. The surface portions of the passages are inclined, so that the incoming radiation impinges at an acute angle onto the surface portions. In this way, the efficiency of the detector and the positional resolution are improved.

Abstract: A detector for detection of ionizing radiation comprises a cathode; an anode; an ionizable gas arranged between these electrodes; a radiation entrance arranged such that ionizing radiation can enter and ionize the ionizable gas; and a readout arrangement. A voltage across the electrodes causes electrons created during ionization of the gas to drift towards the anode, where the readout arrangement detects them. To reduce the risk of occurrence of sparks, and/or to reduce the energy in occurring sparks, one of the cathode and anode has at least the surface layer facing the other electrode made of a material having a resistivity of at least 5×10−8 &OHgr;m.
