Machlett Therapy Tube







Heavy water-cooled tube, 13(32.5cms)long, 5 (12.5cms) diameter, weighing 6 lbs (2.75 Kgs), dating probably to the early 2nd half of the 20th Century.


Intended for superficial radiotherapy. Unknown specifications.


Note the metal belt around the middle of the wide part of the tube, masking the space between the line filament and the opening of the hooded anode. A smaller metal belt is visible more to the right in the picture.


A tube of the same shape, of larger size, equally water-cooled, was also produced by Machlett, possibly intended for deep (?) radiotherapy.


The tungsten target is seated in the deep copper(?) hooded anode, with the focal spot (of the line-focus type) just behind the beryllium window.
