The hadron collection system is a key element in the neutrino beam production in the case of conventional or Super–Beam cases. For the CERN SPL to Fréjus 4 MW/50 Hz Super–Beam, the collection system, a magnetic horn, will be in very sever conditions never experienced in the past. A careful study of all elements of this system must be done taking into account that the target will be located insi...

Synthetic aperture methods are commonly-used techniques for providing images with super-resolution qualities. We propose an improved design of the system, coined "synthetic aperture with Fresnel elements". The super-resolution capabilities of the proposed scheme are analyzed and experimentally demonstrated.
