Air scanner holding device for mounting the LA48 linear array to the LINAC gantry

• Accommodates the LA48 linear array for fast profile measurements of dynamic and conventional fields
• Mounts on the LINAC gantry for profile recording at arbitrary gantry angles
• Includes two acrylic build-up plates for profile measurements at different depths

The air scanner holding device makes it possible to mount the LA48 linear array on the accessory tray of a linear accelerator for profile measurements free in air with a spatial resolution of 8 mm. The device includes an adapter plate, which fits into the guide rails of the LINAC accessory tray. It can be inserted into the rails by 90° rotation to measure inplane and crossplane profiles. The design of the adapter plate depends on the accelerator type, which the customer has to specify. Since the linear array is fixed to the accelerator gantry, profile measurements can be done at different gantry angles to check the consistent performance of the LINAC collimators. Two acrylic build-up plates for profile measurements at depths of 10 mm and 25 mm are included.
