Non-Gaussian beam distributions around the Gaussian core can be formed in an accelerator in both the transverse and longitudinal directions. Since there are no clearly defined criteria to distinguish the halo from the core, the measurement of the halo structure without affecting the core is challenging. Previously, a novel design of an iris diaphragm detector for transverse beam halo distributions and transverse profile (iris diaphragm e-beam apparatus series - halo, or IDEAS-halo) was reported by Euclid Techlabs*. This multi-purpose design not only measures the transverse beam distribution but may also work as a tunable collimator or an adjustable BPM. In this paper, the newest version of the IDEAS-halo and beam experiments using the ~ 2 MeV electron beam at the AWA Cathode Teststand (ACT) of ANL, and the ~ 600 keV "brazeless" compact accelerator beam at Euclid are discussed.
