Deliverable – Final Design Study Report
Identify priorities and plan their implementation as a function of overall schedule and the existing facility
Assess the implications of any modifications in terms of resources, infrastructure and planning.
Address the issues and provide acceptable solutions in the form of conceptual designs and reports.
Extrapolate these issues as a function of proton intensity increase and secondary beam requirements.
Through previous experiences and collaborations, identify the issues associated with the existing facilities.

9. Ventilation Issues
To address the ventilation issues with the aim of reducing the amount of ionized air released to the atmosphere.
Approach:
Separate the ventilation system of the target area from that of the Class A laboratories with the inclusion of an air tight lock
