Cube-Solenoid-07

A coil-set in a two-layer magnetic shield. With a solenoid (diam. 338 mm) and a cubic set of three coil pairs, for DC and AC. It has a maximum access space for this shield size.

BH170-IN

A coil-set of 270 mm (larger pair), for three axes. It generates 500 microT/A per axis, to 2 mT (20 Gauss) in a steady way. Specially constructed to be introduced in a test hole of 300 mm in diameter. A very strong assembly.

BH300HP-1-B

A power coil-set, on one axis, of 300 mm in diameter.  It generates  850 microT/A, to 8,5 mT (85 G) in a steady way. DC and AC.

 It is shown also in the following picture.

BH800-3-A and

BH300HP-1-B

Three-axis coil-set of 800 mm in diameter. It generates 333 microT/A (3.33 G) on each axis, to 1 mT (10 G) in a steady way. DC and AC.

It is shown with a power pair of 300 mm installed at its centre.

BAH600-3-B

Three-axis. Four coils per axis. The larger coils are of about 600 mm by side.

Minimum obstruction on the Z-Y plane due to the coils.

Better field homogeneity than Helmholtz coil-sets of similar size.

Designed for experiments with beams of polarized neutrons it could be useful in other aplications.

BH156-HP-B

Of 156 mm effective diameter. To 38 mT (380 G) in a steady way (to 50 mT with a fan). It could include a second pair for high frequencies and a sample holder (as in the photo). Well suited for  ferroelectromagnetic and metrological purposes.

BH300-3-HP-B

Of 300 mm in nominal diameter. High power on three axes. To 4 mT (40 Gauss) on any axis. To 6.5 mT (65 G) on Z-axis.

BH1600HF1-3-A

Of 1600 mm in diameter, for high frequencies (>1MHz), with pedestal and with  stand of variable height for DUT. Supplied dismantled.

We can supply coils like these with diameters to 1800 mm, for low and high frequencies.
