TI - Update of Adjustable PMQ Lens J2 - Proc. of LINAC2022, Liverpool, UK, 28 August-02 September 2022 CY - Liverpool, UK T2 - International Linear Accelerator Conference T3 - 31 LA - english AB - Gluckstern’s adjustable permanent magnet quadrupole (PMQ) lens based on five rings is revisited to achieve a compact focusing system for laser-accelerated beams. The first prototype was fabricated for bore diameter of 50 mm. The integrated gradient was up to 6.8 T. A new PMQ with a bore diameter of 25 mm is under fabrication based on the same geometry. While the first prototype unit was developed for the final focus magnet of the ILC, the sec-ond unit is the first doublet element for laser-accelerated electron beam focusing to be combined with this first unit. The current status of the development is reported.
