The application provides an angle-variable chamfer pad structure for a desktop
cyclotron, and belongs to the technical field of small cyclotrons. The angle-variable chamfer pad structure is characterized in that: the structure is formed in a mode that the fixed
cutting height H and length L and the variable chamfer
cutting angle are adopted, so that the
cutting volume of the chamfer pad and the pad amount are in
linear relationship; the cutting volume and the pad amount are in
linear relationship, that is, the side surface of the side adjacent to the high-frequency cavity is divided into two parts, the lower part is a long rectangular
vertical plane penetrating the small
radius to the large
radius of the insert strip, and the upper part is a curved surface with an inward opening chamfer adjacent to the upper edge line of the long rectangular
vertical plane; and the application solves the problem that the increasing of the main magnetic pole opening angle of the desktop
cyclotron causes the high-frequency cavity installation space to be nervous or even occupied by adopting the mode that the fixed cutting height H and length L and the variable chamfer cutting angle are adopted.
