Abstract :
An adjustable permanent magnet quadrupole has been developed for the final focus (FF) in a linear collider. Recent activities include a newly fabricated inner ring to demonstrate the strongest field gradient at a smaller bore diameter of 15 mm and a magnetic field measurement system with a new rotating coil. The prospects of the R&D will be discussed.
