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

The first design integrated a Concrete floor. -14° azimut allowed floor clearance for
3 slides of 3 filter positions each.
