7. Summary of main conclusions:

• Mechanical re-design:
  • Seek to shorten shaft by moving flange that mates to bellows to coincide with stator bottom plate;
  • Length of shaft (i.e. penetration into beam) to be reviewed by M.Apollonio and A.Dobbs;
  • Agreed:
    • Clear requirement to deliver working target with improved liability for installation in the April shutdown.  Therefore, need to proceed with manufacture straight away to avoid significant risk of missing the deadline;
    • Benefits may accrue from revising the material at the target tip.  To study the implementation of this now was felt to carry to large a risk of missing the April deadline.  We therefore agreed to study the issue of the material offered to the beam as a second upgrade;
    • Proceed with manufacture of re-designed mechanism presented.  In view of need to begin procurement of long lead-time items straight away, JT/KL/AN will draft one-page summary for TB meeting in Harbin summarising proposal;
    • Tribologists to be identified and invited to target-system upgrade review.
• Electrical:
  • Additional 'K-type' thermocouples not required on the chiller.
• Electronics/control upgrade:
  • Development of prototype system to go ahead (A.Dobbs/J.Leaver).;
  • Proposed schedule for implementation to be documented and presented in document submitted to  target-system upgrade review.
• Software:
  • Further feedback from MICE to be collected at CM23.  Then, implementation plan to be documented and presented in document submitted to  target-system upgrade review.
• Comments from ISIS colleagues at close of meeting:
  • D.Findlay: Stated upgrade plan presented is acceptable to RAL/ISIS and seems to be the right way to go;
  • J.Treadgold: Noted that  there is little time before the April shutdown and emphasised that to achieve the deadline the target team must adopt the design presented as the baseline and take a single minded approach to constructing the project plan, identifying decision points, and carrying out the build and QA procedures defined in the project plan.
