High Performance Simulations of 704 MHz Superconducting Cavities

Mesh files

Four cavity cryomodule -- incorrect interconnection region (2X as long as the design).

  • Long inter-connect:

Four cavity cryomodule -- tapered interconnects.

  • Nominal inter-connect.:

Four cavity cryomodule -- No tapers

  • No taper.:

Eight cavity cryomodule -- incorrect interconnection region (2X as long as the design).

Results

Single Cavity

Lots of results for single cavities -- HOM spectra, R/Q, etc.

Four-cavity cryomodule

  • Inter-cavity coupling for three interconnection designs. There are 100 modes here, corresponding to 5 pass-bands (1 passband = 4 (cavities) * 5 (cells) = 20 modes):

  • Mode 56 E-field magnitude (9.696 MHz) -- 6 cm tapered interconnect:

Full, eight-cavity, cryomodule

A final set of results for the full, eight-cavity, cryomodules.
