Abstract
In order to permit a mounting and demounting of targets free of tools and essentially of friction, snap pins are provided on the system side which, when the target is inserted, automatically engage in a groove which is machined laterally into the target. A releasing slide permits the return of the pins. When the cooling system is acted upon by pressure, a heat transfer membrane is placed against the rear of the target and presses the target onto the snapped-in pins. The pins are released by a releasing slide after the cooling system is relieved from the pressure.
