Collimation Coil
We have developed several magnetic-coil based beamline elements for focusing and steering electron beams. The collimation coil creates a strong on-axis magnetic field along the propagation axis of the electron beam. This results in strong transverse focussing of the electron beam, the focal point can be adjusted by changing the current running through the coil. The focussing coil is ideal of cancelling the exit-kick of the photogun or for creating very strong foci. The coil is wound from rectangular wire assuring excellent thermal contact between the coil and the water-cooled housing.
