2. 2 Overview Project Modification Work to Date Imminent Work Semester Completion

3. 3 Overview Project Modification Work to Date Imminent Work Semester Completion

4. 4 Changes Schedule modification Scrap prototype construction Final design & construction Alpha Design - Front Cross-section

5. 5 Design: Changes Dropping prototyping Original plan: 2 prototypes, 1 final Time & material constraints Purpose of Beta Prototype assimilated into Alpha Formal adoption of cylindrical “Fire-Hydrant” chamber design

6. 6 Schedule: Changes Dropped Alpha Prototype construction Completely dropped Beta Prototype - design & construction Considering material, time, purpose A bit behind schedule

7. 7 Schedule: Changes New schedule includes anticipates delivery of final design by April 10 Construction of vessel to be completed by third-party Likely ‘Florida Precision’ in Melbourne Requirements to be discussed in next 1-2 weeks

8. 8 Overview Project Modification Work to Date Imminent Work Semester Completion

9. 9 Design Work Design of Alpha Prototype completed in November Not to be constructed Visualization of system, component requirements Initial box design for simplicity Box design structurally insufficient Calculations on “Fire-hydrant” design finished [ASME] for circumferential and transverse stresses, respectively

10. 10 Design Work Alpha design - Minimum workable dimensions Allowed for translation system visualization

11. 11 Design Work 6 electrical/optical feedthroughs Bellow design Wedge grips for material testing Swagelock™ fluid feeds Design components from vacuum systems Alpha Design - Front Cross-section

12. 12 Design Work ASME pressure vessel regulations Utilization of manual allows for design with appropriate recommended factor of safety - COMPLETE Welds Material properties Vessel stress Joint efficiencies.25-in thickness more than enough to contend with 115-psi internal pressure [ASME]

13. 13 Overview Project Modification Work to Date Imminent Work Semester Completion

14. 14 Design Work Integrate ASME regulations into Final Design Discuss fabrication with Florida Precision Integration of fabrication requirements into ASME calculations (weld & joint efficiencies - note variable ‘E’) Complete final design: conceptual -> DETAILS

15. 15 Overview Project Modification Work to Date Imminent Work Semester Completion

16. 16 Semester Finale Utilizing final design concepts: Work-in final dimensions Complete full ASME validation calculations Deliver design to Dr. Brenner, Dr. Flemming If possible, order clamps Final deliverable of a complete cryogenic environmental testing chamber
