A 4-cavity 3.9 GHz cryomodule has been constructed at Fermilab and delivered to DESY. Its intended use is to linearize the non-linear beam energy-time profile produced by the 1.3 GHz accelerating gradient and thus improve the operating characteristics of FLASH for its users. First cold testing of the module is expected in the near future prior to its installation. We will report on the performance of the cavities, assembly and transport of the module as well as anticipated testing, installation, and commissioning plans.

Fermilab, in conjunction with our colleagues at KEK, RRCAT, and BARC, is developing several main linac SRF cryomodules in support of Fermilab’s Project X and the International Linear Collider. The Type IV Cryomodule (T4CM) will allow Fermilab to design, fabricate, and test our first cryomodule completed entirely in the USA. This cryomodule will also probe the stability question of mounting a magnet system under the center, fixed support post. Using the T4CM as the baseline, Fermilab and our Indian colleagues are developing a “unified” cryomodule for Project X which will allow for options to mount up to three magnets with either beta1 or beta.81 cavities. Fermilab has also supported the development of the S-1 Global cryomodule which will be built and tested at KEK. Fermilab’s commitment is to deliver two fully dressed cavities and all supporting components. To accomplish these designs, modern CAD tools using parametric designs, 3-D visualization JT files, and collaboration tools have been implemented. With these designs, Fermilab has spearheaded the effort to work collaboratively using a common database; DESY’s EDMS.
