Superconducting Radio Frequency (SRF) cavities are becoming the preferred method of particle acceleration for many new high energy physics projects around the world. These SRF cavities are assembled in series into a thermal structure known as a cryomodule (CM). Currently, Thomas Jefferson National Accelerator Facility (JLab) is providing the superconducting cryomodules for both the Spallation Neutron Source (SNS) and the prototype for the energy upgrade to the JLab Continuous Electron Beam Accelerator Facility (CEBAF). Once completed, the cryomodules are assembled in series to form a superconducting linear accelerator (LINAC) utilized primarily for particle physics research and development. During operation, the cryomodule maintains the temperature of the cavities at 2 K, while the external shell of the cryomodule is at ambient temperature (293 K). This paper will present the design, fabrication and assembly of the CM components in order to optimize thermal performance, which is vital to the SRF cavity operation. This thermal optimization will include both static and dynamic heat load considerations as well as design and assembly techniques.
