  1. Cavity Tin Seals MTA RF Meeting Steve Virostek – LBNL August 25, 2009

  2. Summary • The following seals related to the 805 MHz cavity have been identified: • Side Plate Seal • Waveguide Transition: WG-1 to WG-2 • Waveguide Transition: WG-1 to Cavity • SMA Probe Seal • Viewport Seal • Various LBNL and FNAL drawings for these seals exist • The following slides summarize which drawings are being used , why these drawings were used and the quantities being produced. Please review for accuracy.

  3. Side Plate Seal • This ~8” diameter seal is for the cavity stainless steel vacuum end caps (2 each on the cavity) • LBNL drawing 21K5233 • FNAL drawing 2130.000-MC-391358 • The two drawings are identical. • Quantity ordered: 60

  4. Waveguide Transition: WG-1 to WG-2 • This ~4” by ~10” rectangular seal is for the cavity half-height waveguide transition (1 each on the waveguide) • LBNL drawing 21K5212 (original & modified version) • FNAL drawing 2130.000-MC-391339 • The LBNL modified version and the FNAL drawing are very similar. The FNAL drawing shows the seal extending 7 to 11 mils into the waveguide. The LBNL modified drawing will be used. • Quantity ordered: 30

  5. Waveguide Transition: WG-1 to Cavity • This kidney shaped seal is for the connection from the waveguide to the existing cavity (1 each on the cavity) • LBNL drawing 21K5223 • FNAL drawing 2130.000-MC-? • The two drawings are virtually identical (<0.005” differences). The FNAL drawing was generated from an old Bob MacGill layout drawing. The LBNL drawing will be used. • Quantity ordered: 10

  6. SMA Probe Seal • This 0.67” ID seal is for the SMA probe (1 each on the cavity) • LBNL drawing 21K5551 • FNAL drawing 2130.000-MC-391359 • The two drawings are identical. • Quantity ordered: 10

  7. Viewport Seal • This 0.714” ID seal is for the viewport • LBNL drawing 21K5201 • FNAL drawing 2130.000-MC-391357 • The two drawings are identical. • Quantity ordered: none needed
