A thorough understanding of halo formation and its possible control is highly desirable for essentially all particle accelerators. Limiting the number of particles in the halo region of a beam would allow for minimizing beam losses and maximizing beam transmission, i.e. the experimental output. Measurements based on either optical transition radiation (OTR) or synchrotron radiation (SR) provide an interesting opportunity for high dynamic range measurements of the transverse beam profile, since the signal is linear with the beam charge over a wide range and is routinely used in many diagnostic applications. In this contribution, first results on beam halo measurements obtained from a flexible core masking technique and an innovative CID camera system are summarized.
