The Instituto de Fmsica da Universidade de Sco Paulo (IFUSP) is building a two-stage 38 MeV continuous-wave racetrack microtron. In this work, we describe the determination of alignment tolerances for the injector system of the IFUSP Microtron. This system consists of a linear accelerator with input energy of 100 keV and output energy of 1.8 MeV. The work presented ere involves analysis of our possibilities of alignment, the beam specifications for the acceleration structures and the strength of the correcting coils. Simulations were made using a method based on rotation matrices that allows for misalignments in the optical elements. It uses a tolerance parameter, given by the user, which is interpreted as a standard deviation of the normal misalignment distribution used to shuffle a configuration. A 5% loss of particles is achieved at a tolerance of 0.25-mm, without the inclusion of correcting coils (steerings) in the simulations.

The ILC requires an unprecedented accuracy and speed for the survey and alignment of its components. The Rapid Tunnel Reference Surveyor (RTRS) is a self-propelled train intended to automatically survey a reference network in the ILC tunnels with a design accuracy of 200 microns over distances of 600 m. A prototype RTRS has been built by the LiCAS collaboration. It will shortly commence operation at DESY. The operation principle of the RTRS will be explained. The status of the project's hardware, software and calibrations as well as the principles and performance of the underlying measurement techniques will be described.

The 24 cell Diamond Storage Ring is 561.6m in circumference and is mounted on 72 support girders, the largest of which are 6m long and weigh 17 Tonnes. Each girder can be remotely positioned in 5 axes using a system of motorised cams. This system has been designed to enable the future remote realignment of the Storage Ring using beam based alignment techniques. The system is described in detail including the mechanical and electrical components of the system as well as a description of the alignment algorithms employed and how these have been incorporated into the control system.
