The industrial production phase for the series quadrupole (QD) units is underway, with 36 units scheduled for delivery to GSI in October 2026. These magnets are critical components intended for the integration into quadrupole doublet modules for the SIS100 synchrotron.
Validation and Infrastructure. 
 
To support the validation and assembly of these components, the project has established the following timeline and requirements:
• Cryogenic Validation: Every series unit must undergo comprehensive magnetic measurement testing at cryogenic temperatures to ensure performance meets superconducting specifications.
• Integration Infrastructure: A test bench has been procured to support the assembly and integration processes.
• Anticryostat Procurement: The necessary anticryostats, essential for the integration of the doublets, have been placed under contract with a scheduled delivery date of September 2026, positioning the facility to receive the magnets shortly thereafter.
 
Stretched Wire (SSW) System
The SSW system is moving toward readiness, with several components progressing through final assembly and calibration:
• Support Structure: Currently under production at the GSI mechanical workshop, with completion expected by June 2026.
• System Hardware & Software: The electronic rack is approximately 80% complete. Software development for the power supply is underway, though the choice of a non-standard power supply model by the GSI team requires additional integration work beyond the initial implementation plans.
• Component Status: The tension cell has been connected and tested. Calibration is scheduled for May 2026, and the 3D machine at CERN is booked for the necessary mechanical calibration. Note that reflector holders are currently unavailable, and pulleys are pending delivery.
• Timeline: The completed support assembly is expected to be delivered to CERN by June 2026.
Rotating Coil Development
The rotating coil system is currently the most significant source of schedule delay in the magnetic measurement development plan.
• Design & Availability: The design is approximately 70% complete. Once finalized, the system is expected to be available by early 2027.
• Components & Assembly: Production of the PCB is planned at CERN. The assembly phase will include the measurement heads and cabling (specifically utilizing AXON and related connectors).
Facility & Integration
Infrastructure at GSI is being prepared to accommodate incoming hardware:
• Room Temperature Tubes: Tubes for room-temperature measurements are scheduled to arrive at GSI at the end of May 2026 for the first four magnets.
• Validation: These systems are critical for the qualification of series quadrupole units arriving in October 2026
