	At the ALBA Synchrotron light source 6 kicker and 3 septa magnets are installed for beam injection and extraction. A 100 MeV beam coming from the linac is injected on axis into the Booster. The full energy (3 GeV) beam is extracted from the booster and injected into the Storage Ring, where 4 kicker magnets bring the stored beam close to the septa. All septa are direct driven out-of-vacuum magnets with C shape iron laminated yoke. The magnets are excited by a full sine approx. 300 μs pulse length; the nominal field is 0.15/0.84/0.9 T (booster injection/extraction/storage-ring-injection). The stray field seen by the stored beam is less than 1 μT. The booster kicker magnets are in-vacuum magnets with C-ferrite yoke. The magnets are excited by a 0.4 μs flat top pulse; the nominal field is 0.03/0.04 T (booster injection/extraction). The storage ring kickers have a C-ferrite yoke and a 0.4 μm Ti coated ceramic vacuum chamber. The excitation is done by 6 μs half sine; the nominal field is 0.13 T. The paper will present the design of the elements and their magnetic characteristics. First results of their behaviour during commissioning will also be discussed.

At the ALBA Synchrotron light source 6 kicker and 3 septa magnets are installed for beam injection and extraction. A 100 MeV beam coming from the linac is injected on axis into the Booster. The full energy (3 GeV) beam is extracted from the booster and injected into the Storage Ring, where 4 kicker magnets bring the stored beam close to the septa. All septa are direct driven out-of-vacuum magnets with C shape iron laminated yoke. The magnets are excited by a full sine approx. 300 μs pulse length; the nominal field is 0.15/0.84/0.9 T (booster injection/extraction/storage-ring-injection). The stray field seen by the stored beam is less than 1 μT. The booster kicker magnets are in-vacuum magnets with C-ferrite yoke. The magnets are excited by a 0.4 μs flat top pulse; the nominal field is 0.03/0.04 T (booster injection/extraction).
