Meeting ID: 160 2832 6423 Passcode: 3DdgRUoscP

Summary

Charles updated the team on schedule adjustments, aiming to finalize assembly by the end of August. Alex shared updates on completed pieces and shipping details, with more updates expected on Thursday. Alexander emphasized the importance of meeting the mid-August deadline and suggested reconsidering the assembly sequence due to new subsystems.

Key Points

  1. Schedule Adjustments

    • Charles updated the team on schedule adjustments based on new information, highlighting the shift in meeting beginnings and the expectation to finalize assembly by the end of August. (0:43)
  2. Completed Pieces and Shipping

    • Alex shared updates from Sushruta, including the completion of the first picture frame piece, 3D printing of an HRPPD sensor, and shipping details for mirror pieces and end rings, with more updates expected on Thursday. (5:55)
  3. Design Updates

    • Alex presented design updates involving gas system additions, inlet and outlet configurations, and considerations for the final design version, discussing the use of tapered pipes and tube mounting strategies. (8:40)
    • Alex outlined the need to finalize the integration of the light monitoring system before making decisions on mirror modifications and discussed remaining tasks like air gel holding solutions. (18:19)
  4. Timeline Concerns

    • Alexander questioned the timeline for assembly starting in mid-August, expressing concerns about tight schedules and the readiness of all pieces for production. This led to a discussion on the project's progress and the need for further communication with key personnel. (20:27)
    • Alexander emphasized the importance of staying on schedule for the mid-August deadline, acknowledging it as crucial for the project's success and suggesting that meeting this deadline is good practice. (22:37)
  5. Assembly Sequence

    • Alexander suggested reconsidering the assembly sequence due to new subsystems, leading to a discussion on mounting everything on the front wall first. (28:43)
    • Alex discussed modifying the HRPPD model with an O-ring groove and considering a regular radial O-ring seal for the final design, aiming to simplify the process. (32:12)

Next Steps

  1. Mirror Updates and Ion Gun Mount

    • Bill to provide updates on the mirrors once samples from Sushruta arrive and work on resizing the ion gun mount based on mirror dimensions. (3:45)
  2. Mounting Diffusers

    • Preet to determine how to mount the diffusers for the light monitoring system and assess if modifications are needed on the mirror. (5:09)
  3. Revised Assembly Sequence

    • Alex to sketch out a revised assembly sequence after mounting the light monitoring system, finalizing the mirrors, and integrating the gas system conceptually, to be reviewed with the team for adjustments. (29:05)
  4. HRpVD Model Modification

    • Alex to modify the HRPPD model by adding an O-ring groove and send it to Alexander for further evaluation regarding the possibility of using a regular radial O-ring seal for the final design. (32:21)
