CLIC Test Facility 3 (CTF3) has the objective to demonstrate the remaining feasibility issues of the CLIC two-beam technology for a future multi-TeV linear collider. One key issue is the efficient generation of a very high current 'drive beam' that serves as the power source for the acceleration of the main beam to high energy. This large current beam is produced by interleaving bunches in a combiner ring using transverse deflecting RF cavities. The 84 m long CTF3 combiner ring and the connecting transfer line have been recently installed and put into operation. The latest commissioning results will be presented.

For the last few years the MAD-X program makes use of the Polymorphic Tracking Code (PTC) to perform calculations related to beam dynamics in the nonlinear regime. An important new feature is the extension of the matching module to allow fitting of non-linear parameters to any order. Moreover, calculations can now be performed with parameter dependence defined in the MAD-X input. In addition, the user can access the PTC routines for the placement of a magnet with arbitrary position and orientation. This facilitates the design of non-standard lattices, in particular since a 3D visualization of a lattice is now available. For the LHC studies during commissioning it is of special interest that one has access to within the thick PTC elements which allows e.g. to find PTC Twiss parameters at any point in the ring. Lastly, the beam-beam element has been added to PTC to complete the set of elements available in MAD-X proper.
