• 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
