Design and advancement status of the Beam Expander Testing X-ray facility (BEaTriX)
D. Spiga, C. Pelliciari, B. Salmaso +10
The BEaTriX (Beam Expander Testing X-ray facility) project is an X-ray apparatus under construction at INAF/OAB to generate a broad (200 x 60 mm2), uniform and low-divergent X-ray…
Roughness tolerances for Cherenkov telescope mirrors
K. Tayabaly, D. Spiga, R. Canestrari +3
The Cherenkov Telescope Array (CTA) is a forthcoming international ground-based observatory for very high-energy gamma rays. Its goal is to reach sensitivity five to ten times bett…
Computation and validation of two-dimensional PSF simulation based on physical optics
K. Tayabaly, D. Spiga, G. Sironi +3
The Point Spread Function (PSF) is a key figure of merit for specifying the angular resolution of optical systems and, as the demand for higher and higher angular resolution increa…
Manufacturing and testing a thin glass mirror shell with piezoelectric active control
D. Spiga, M. Barbera, A. Collura +12
Optics for future X-ray telescopes will be characterized by very large aperture and focal length, and will be made of lightweight materials like glass or silicon in order to keep t…
Testing multilayer-coated polarizing mirrors for the LAMP soft X-ray telescope
D. Spiga, B. Salmaso, R. She +13
The LAMP (Lightweight Asymmetry and Magnetism Probe) X-ray telescope is a mission concept to measure the polarization of X-ray astronomical sources at 250 eV via imaging mirrors th…
BEaTriX, expanded X-ray beam facility for testing modular elements of telescope optics: an update
Carlo Pelliciari, Daniele Spiga, Elisa Bonnini +4
We present in this paper an update on the design of BEaTriX (Beam Expander Testing X-ray facility), an X-ray apparatus to be realized at INAF/OAB and that will generate an expanded…
