Presentation Transcript

  1. RF Cavity update Feb 2005 G. Gosling Mech Eng.

  2. Sources of latest information • MICE web-site (schematic drawings) • Derum Li presentation to LBNL colab. mtg • Discussions with: • Steve Virostek (LBNL) • Bob Rimmer (jLab)

  3. Coupling coils now defined. Greater spacing between cavities Main change - All cavities now identical and independent of each other.

  4. Current status • Port formation problem is now believed solved. • First 2 Be windows failed, third due soon and there is confidence from the supplier. • Cavity requires further electro-polishing before testing. • Cavity will be tested at Fermilab under non-representative external conditions.

  5. Fermilab test conditions • Cavity will be rigidly bolted through both stiffener rings to free-standing fixture. • Cavity will work in atmospheric conditions under internal vacuum. • Tuning will be conducted manually and must compensate for operating pressure difference.

  6. Next phase • Prototype cavity off for finishing and test at Fermilab – April 2005. • No current design work ongoing at LBNL. • IC to get involved and assist with design of tuning and cavity support equipment.

  7. RF 2D view

  8. Problems • Define Cavity and Shell parameters for: • Manufacturing tolerances • Physical properties • Behaviour under running conditions • Operators’ requirements • Design constraints • Materials, processes, available space.
