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.
* Fields marked with an asterisk are required.
Data from our simulation tool. Our simulator has been calibrated to obtain values of magnetic field and homogeneity lower than the reality with an error rate between 0 and 5%.
