Electromagnet before 2019-09-10¶
This page lists the parameters of the first version of the FFT electromagnet that was installed in the FFT end-station from the start of SCS operation up to the 10th of September 2019 when an improved version was put in place instead.
Magnetic field as function of current in the electromagnet. From elog 270.
| Voltage | Current | Field |
|---|---|---|
| V | A | mT |
| 0 | 0 | 4 |
| 1 | 1.3 | 50 |
| 2 | 2.6 | 98 |
| 3 | 4 | 150 |
| 4 | 5.3 | 200 |
| 5 | 6.5 | 250 |
| 6 | 7.7 | 283 |
| 7 | 9 | 315 |
| 8 | 10 | 335 |
| 9 | 11.1 | 355 |
| 10 | 12.2 | 362 |
Temperature of the electromagnet for different settings. From elog 270.
The magnetic field generated by the electromagnet is shown in
electromagnet_field.
| gap between pole (mm) | maximum current (A) | maximum field (T) |
|---|---|---|
| 7.7 | 12 | 0.37 |
The temperature reached near the coil winding edge on the pole is shown in
electromagnet_temperature. Combination of 5°C cooling and high water
flow-rate should keep the coil temperature <50°C when operating at 12 A in
vacuum.
The geometry of the pole shoe is defined in CAD file.
