Delivering high-precision programmable DC current from 1.5 kW to 10 MW for dipole, quadrupole, corrector, and beam-steering electromagnets worldwide.
Magna-Power particle accelerator magnet supplies combine sub-ppm fluxgate current transducer sensing with robust current-fed power conversion topologies.
Designing high-precision DC power supplies for particle accelerator electromagnets presents fundamental electromagnetic and thermal challenges that standard voltage-fed power supplies cannot address.
Electromagnets used in particle accelerators—including dipole bending magnets, quadrupole focusing lenses, sextupoles, and fast steering correctors—exhibit immense inductance. When driving highly inductive loads ($L/R$ time constants spanning seconds to minutes), traditional voltage-fed switch-mode power supplies suffer from control loop instability, output filter capacitor ringing, and vulnerable internal energy storage during rapid voltage transitions.
Magna-Power’s proprietary current-fed topology replaces bulky output capacitive banks with an internal current-fed inductor on the DC bus. This fundamental architectural distinction offers three major benefits for accelerator applications:
Modern synchrotrons, cyclotrons, colliders, and light sources require magnetic field stability measured in parts-per-million (ppm). Thermal drift, ambient temperature swings in gallery halls, and line-frequency ripple can alter particle trajectories, causing beam emittance degradation or loss of beam confinement.
To eliminate these drift sources, Magna-Power developed the DBx High-Stability Option. By pairing precision zero-flux closed-loop fluxgate current transducers with ultra-low temperature coefficient ($TC < 1\text{ ppm/}^\circ\text{C}$) internal voltage references and 24-bit delta-sigma conversion, MagnaDC supplies achieve extraordinary performance:
From low-power orbit corrector magnets to megawatt main-ring dipoles, select the ideal platform tailored to your beamline configuration.
The DBx module is an integrated hardware extension available across all MagnaDC power supplies. Utilizing zero-flux fluxgate transducer technology, it upgrades standard current regulation loops to sub-ppm stability for synchrotron beam focus and ion therapy beam-gantry magnets.
Designed for space-constrained rack environments in accelerator equipment galleries. The 1U SLx and SL Series are ideal for driving steering correctors, skew quadrupoles, hexapoles, and injection line magnets where high power density and digital integration are essential.
The workhorse of industrial and research physics magnet systems. The TS Series provides robust current regulation, wide voltage ratings up to 1000 Vdc or current up to 4000 Adc, perfect for compact cyclotron main coils and medium-scale particle beam focusing racks.
For large hadron colliders, heavy-ion synchrotrons, and high-energy physics research centers. Available in air-cooled (MT) and liquid-cooled (ML) cabinet configurations with master/slave paralleling capability for massive magnet field generation.

Key technical evolutions shaping the next generation of particle physics infrastructure, light sources, and medical proton therapy centers.
As laboratories migrate to HTS magnets operating at higher magnetic fields (15T to 20T+), power supplies must deliver extreme current ramp rates without inducing voltage instabilities during non-linear flux transitions.
Procurement specifications increasingly require seamless integration into EPICS (Experimental Physics and Industrial Control System) and TANGO frameworks. Standardized SCPI commands over IEEE 488.2 and LXI Ethernet enable automated beam tuning via AI agent algorithms.
With megawatt power budgets under strict sustainability metrics, water-cooled power supplies (ML Series) with direct heat dissipation into central facility chilling loops reduce gallery HVAC power loads by over 85%.
Global supply chain bottlenecks have elevated vertical integration from a preference to a critical risk mitigation requirement. Facilities favor suppliers who perform sheet metal fabrication, magnetics winding, SMT PCB assembly, and burn-in under one roof to guarantee 4-6 week lead times.
Procurement teams avoid single-point legacy power supplies. Modern magnet galleries utilize standardized modular units that can be configured in master-slave parallel arrangements to support future beamline energy upgrades without complete power system replacement.
Accelerator facilities operate over 20 to 30-year horizons. Procurement criteria require guaranteed long-term spare parts availability, backward-compatible control electronics, and local regional service centers in North America, Europe, and Asia-Pacific.
