This shielded high vacuum x-ray tube was produced by E. Machlett & Son (founded 1897), early producers of commercial x-ray tubes in the United States. The tube measures 19" long and 4 1/2" around at the middle and dates to about 1930 - 1935. (picture of tube without shielding) It is a high vaccum tube that ran at 60 kv dc, 5-10 ma and was used for diagnostic x-rays or light theraputic use (such as surface lesions). The cathode is to the left and the anode to the right. A multi-layered heat sink screws into the anode assembly. The tube is encased in a molded 3/8" thick lead glass sleave that is bolted together at the center. The cathode is connected to the filament voltage with a standard male electrical plug type connector. |
