Good gradients in seconds flat

Levelling tilts

Ideally, the gradient curve is flat at its peak, as on the left, which shows gradients when no beam is loaded into the cavity. When beam is brought into the cavity, tilts appear, as on the right. Scientists were able to achieve flat gradients in cavities with beams of up to 5 mA. Image: Julien Branlard
