Permanent magnet (PM) multipoles are very attractive for beam transportation and focusing in accelerators. The primary advantages over electromagnets are no power supply and no cooling systems, better maintainability. A PM quadrupole is supposed to be utilized in the DC140 cyclotron destined for acceleration of heavy ions which is under construction in JINR, Dubna. The extracted ion beam passes through a region where the stray field reduces sharply. Horizontal focusing of the beam line will be provided with a passive magnetic channel (MC1) and a PM quad (PMQ) in the strong and low field regions, respectively.
