Transforming theoretical beam dynamics into physical reality.
We offer precision manufactured Pure Permanent Magnet (PPM) Halbach Arrays.
They are suitable for Synchrotrons, Free-Electron Lasers (FELs), and advanced particle accelerators.
The physics of an Insertion Device is complex.
The manufacturing challenge is clear: minimize phase error and optical trajectory wander.
We achieve this through a rigorous production protocol.
That includes individual block characterization, algorithmic sorting, and cleanroom assembly.
No matter you need a short-period In-Vacuum Undulator (IVU), or a high-flux Wiggler.
We deliver arrays that meet strict specifications for First and Second Field Integrals (I1, I2).
Manufacturing & Assembly Process
Block Characterization & Sorting:
We do not simply assemble magnets.
Every individual block undergoes 3-axis Helmholtz coil testing and Hall probe scanning.
The purpose is to map its specific magnetic moment vector.
We then use Simulated Annealing algorithms.
Determine the optimal position of each block within the array.
Mathematically cancel out bulk material inconsistencies.
Ultra-High Vacuum (UHV) Compatibility:
Surface Treatment:
We offer specialized coatings.
Including Titanium Nitride (TiN) (5ยตm) and Nickel-Copper-Nickel.
Prevent outgassing and protect against radiation damage.
Adhesives:
We use low-outgassing structural epoxies.
Fully cured and baked out to ensure vacuum stability down to 10โ9 Torr.
Mechanical Precision:
The magnetic gap in an undulator is often <10mm.
We manufacture the carrier beams (strongbacks) and magnet holders.
They feature <10ยตm mechanical tolerance.
Ensure perfect parallelism across the entire length of the device.
Custom Design Configurations
Select the topology that matches your spectral requirements.
A. Planar Halbach Undulators (PPM)
Design:
The industry standard K=4 Halbach array (โโโโ).
Application:
Generating high-brightness, linearly polarized radiation.
Capability:
We can manufacture variable-gap arrays where the magnetic force is perfectly balanced to prevent mechanical deflection of the support structure.
B. Cryogenic & In-Vacuum Undulators (IVU)
Design:
Arrays designed to operate inside the vacuum chamber.
Often at cryogenic temperatures (77K) to maximize coercivity (Hcj) and Remanence (Br).
Materials:
We use PrFeB (Praseodymium) or NdFeB grades.
They are optimized for low-temperature transitions (Spin Reorientation limitation).
C. Multipole & Focusing Wigglers
Design:
High-K arrays designed to shift the spectrum to higher energies (Hard X-Rays).
Capability:
We can integrate side-magnets or shaped poles.
Provide strong focusing gradients, assisting in electron beam confinement.
D. Radiation-Hardened Arrays
Material:
Sm2Co17 (Samarium Cobalt).
Why:
For high-energy storage rings, radiation demagnetization is a primary failure mode.
Our SmCo grades offer superior resistance to radiation damage compared to NdFeB.
Ensure long operational lifecycles.
Don’t let manufacturing tolerances ruin your spectrum.
