CM2 is the second 1.3GHz Cryomodule assembled at the Cryomodule Assembly Facility (CAF) in Fermi National Accelerator Laboratory. The string has a doublet magnet, beam position monitor and eight cavities. All the cavities are qualified at 35 MV / m gradient at the Horizontal Test Facility before assembly. The dressed cavities were outfitted with magnetic shielding, blade tuner, and the cold mass was assembled based on the Tesla TTF Type III+ cryomodule design. CM2 is currently being installed into the test stand in NML where it will be cooled down and high power tested. CM2 will also be the first cryomodule that an electron beam will be put through at the NML facility. This will be a proof of principle for the planned Advanced Superconducting Test Accelerator (ASTA) facility at NML. This paper describes the assembly steps, the quality assurance methods and the challenges that we experienced during assembly and qualification steps at CAF. De

  A software system has been developed to automate cavity tuning machines as part of a multi-laboratory collaboration. The system is based on a plugin framework containing a configurable set of components. Each component runs asynchronously and uses a framework for message based communication. Components run in either manual or automatic mode. In automatic mode, the system interprets a user-selected control script which executes a sequence of measurements, model calculations and tuning operations. A tuning script iterates until the prescribed tuning criteria are satisfied, or until aborted or paused by the user. In manual mode, the user controls the tuning process, deciding when and which component to run, and when tuning is complete. The software framework incorporates the blackboard architecture for sharing data and results between the various plugins. The results of the measurements and tuning are persisted in an XML-based data store, and components exist that retrieve and visualize the data. The software system is portable (Linux, Windows) and has been successfully deployed and used by Fermilab, DESY, and KEK.
