QUADRUPOLE ACCELERATION STRUCTURE (OPTIONS) Russian patent published in 1997 - IPC

FIELD: acceleration engineering; ion beam accelerators. SUBSTANCE: structure has case whose internal side surface mounts electrodes joined with respective surfaces at electrode foot. Case is provided with access ports for electrode displacement devices used during electrode adjustment and radio measurements. Electrodes are provided with mounting and fastening members for electrode displacement devices. Joining electrode mounting surfaces and case provides for holding electrodes at right angle to respective mounting surfaces of case. Planar or shaped spacers may be inserted between mounting surfaces of case and electrodes incorporating provision for fitting shape of electrode mounting surface to that of spacer top. In first option, case is monolithic and in second option it is sectionalized. EFFECT: facilitated adjustment of electrodes, reduced time of adjustment, that may be conducted concurrently with radio measurements; improved stiffness of structure. 7 cl, 8 dwg
