Summary

The meeting focused on transitioning to a picture frame design for improved structural integrity and reduced manufacturing complexity for the HRPPD mounting. Key discussions included the use of threaded bosses and silicon seals, potential interference with the pyramid mirror, material and bending considerations, and the gas system design.

Key Points

  1. Transition to Picture Frame Design for the HRPPD Mounting

    • Alex discussed transitioning from a t-beam design to a picture frame design, highlighting benefits in structural integrity and manufacturing complexity reduction. (4:27)
    • The final design layout was explained by Alex, involving threaded bosses, silicon seals, and picture frames instead of t-beams. He clarified sensor placement and the prototype nature of the current models. (8:19)

  2. Pyramid Mirror Integration

    • Bill raised concerns about potential interference with the pyramid mirror, leading to a discussion on integrating the pyramid mirror with the current design. (10:28)

  3. Material and Bending Considerations

    • Ashark inquired about the material and bending of the table, prompting a discussion on carbon fiber, resin, and peak bolts for assembly. (16:23)

  4. Gas System Design

    • Alex discussed the gas system design with Prashant, covering the need for a one-inch pipe, pass-through considerations, and flow requirements for the final design. (28:25)

  5. Construction and Assembly Updates

    • Sushrut presented updates on changes in construction, mold design, layup process, and assembly sequence, followed by progress in simulation work. (34:18)

  6. Alignment Process

    • Prakhar explained the alignment process using precision pins and microscopes to ensure accurate alignment of holes on the end rings. (46:01)

  7. Schedule Delay

    • Charles acknowledged a delay of one week to ten days due to the late arrival of end rings. (51:12)

Next Steps

  1. Two-Step Pressure Test Plan

    • Alex to discuss with Sushrut the two-step pressure test plan, including baseline testing with an aluminum plate and NPT pass-through, followed by a second stage test with dummy sensors for design adjustments before the full-scale prototype. (19:43)

  2. Alignment of End Ring Holes

    • Alex and Sushrut to ensure alignment of holes on both sides of the end ring by clocking one of the holes to the 12:00 position on both sides to avoid issues faced in the past with TPC. (42:11)
