Installation of Cavity Magnet - 20th of June 2007

This week we have installed the magnet around the cavity. This magnet will collimate and focus the electron beam exiting the accelerator cavity.

The magnet consists of an iron return joke and of hollow copper windings for water cooling. The windings are separated into nine sections. The current is connected in series through the section, while the water cooling is parallel through the section.

The Magnet is ready for installation. The bore of the magnet is large to be placed around the stainless steel container of the cavity.

For installation the stainless steel container has to be removed. The magnet will be attached to the aluminum 'manipulator'. With this support frame we can adjust the orientation and position of the magnet with respect tot the cavity.

The magnet is installed and the stainless steel container is put back into place.

Side view. You can see the bars with tubes. By turning the tubes the length can be adjusted so that the magnet orientation of position can be alterned.

The space between the magnet and stainless steel container is just a few milimeters. Just big enough manipulate the orientation and position of the magnet.

The weight of the magnet is supported by a spring. This makes the movement of the magnet much easier.
