Specific request
Our means of simulation and our know-how allow us to manufacture a custom-made electromagnet according to 5 criteria:
- Air gap
- Maximum field
- Homogeneity
- Speed of field variation
- Mechanical constraints (Optical access, UHV, size, mass, etc)
CAYLAR designs and manufactures magnetizing coils, vacuum chambers and current sources which offers a great flexibility for the design of an electromagnet. It is possible to adapt the coils to an existing power supply.
