Abstract

1282498 Particle spectrometers; X-ray tubes ASSOCIATED ELECTRICAL INDUSTRIES Ltd 17 Nov 1970 [17 Nov 1969] 56142/69 Heading HID In apparatus which is for use in electron spectroscopy and in which a sample 6 may be irradiated with X-rays generated by bombardment of a target electrode 8 with electrons supplied by an electron source 14, said target electrode and said electron source are detachably mounted on a hollow body 1, 2 so that at least part of the target electrode 8 and of the electron source 14 lie within the cavity 13 in said body which is also adapted to contain the sample 6 to be investigated mounted close to said target electrode 8, the said body 1, 2 having an opening 38 through which pass for analysis electrons released from a sample, e.g. upon irradiation thereof by X-rays as aforesaid, and the path 36 of said released electrons through said opening being generally parallel to the path of the electron beam from the electron source 14 to the target electrode 8. A cylindrical electrode 9 may be maintained at a suitable potential to reduce the energy of the released electrons prior to their admission to an electromagnetic analyser or to a scanning electrostatic analyser (Fig. 3, not shown) provided with an electron multiplier and a counter or other display or recording device. The parts of the target electrode 8 and electron gun 14 projecting into the cavity 13 are surrounded by a generally tubular copper member 16 provided with a window 17, e.g. of Be or Al and a pumping port 37. The Cu target electrode 8 has a bombardment surface 23 coated with Mg or Al and is water-cooled internally. Sample inserting equipment (Fig. 4, not shown) includes means for rotating the rod 7 on which four samples 6 are mounted, means for heating electrically or cooling the samples, e.g. with liquid nitrogen, and a vacuum lock arrangement for maintaining the vacuum in the cavity 13 during the insertion of new samples. The body 1, 2 has a plurality of ports 24-30 to which the sample inserting equipment or other ancillary equipment may be connected, e.g. ion bombardment equipment for cleaning the sample; equipment for irradiating a sample with charged particles or light from a U.V. lamp; or a cup containing a liquid sample.
