• ASTRID2 will be operated in top-up mode using ASTRID as a booster

Long cycle time of ASTRID, ~10 s

• 1 ¼ turn ASTRID extraction using the existing DC septum (12mm, 9°) and new

fast kicker (150 mm long, 132 gauss, <50 ns, flat-top jitter < ±0.02)

• Transfer beamline to take the beam below ASTRID2 through the girder injecting

into ASTRID2 from the inside.

• Beam is injected into ASTRID2 with a pulsed septum (15°)and 3 bumpers

(250 Gauss)

• ASTRID2 commissioned alternating with ASTRID operation and beamline

transfer → minimize dark period

ASTRID → ASTRID2
