Expected changes of the Technical Specifications

- The complete system can be bolted to a reference surface as a single unit

- The lead castle is mounted flush with the ‘Downstream’ side of its support structure

- Only the field correction filter mount is provided

- The “Main” collimator becomes square +/- 37°

- A “4th layer” lead filter is manually attached to restrict the collimation window

- The filter changer design is proposed but remains optional

- The irradiator console and the automated filter changer are two distinct (modular) entities for safety and repair

- The filter changer module communicates with the environmental controls and collects “Source Exposed” + “Shutter” + “Live” signals from the irradiator console

Difference between +/- 37° and +28°/-14° filters

The first design integrated a Concrete floor. -14° azimut allowed floor clearance for

3 slides of 3 filter positions each.
