Measurement for the $e^+$ beam purity at the CERN-SPS H8 beamline / Bisio, Pietro (INFN e Universita Genova (IT)) ; Celentano, Andrea (INFN e Universita Genova (IT)) ; Marsicano, Luca (INFN e Universita Genova (IT)) ; Bondi, Mariangela (INFN e Laboratori Nazionali di Frascati (IT)) ; Marini, Anna (INFN e Universita Genova (IT))
This Note describes the $e^+$-beam purity measurement for the H8 beamline of the Super Proton Synchrotron (SPS) at CERN. This study was performed in the context of the POKERINO prototype characterization, conducted during a week of measurements in the summer of 2023 at the H8 beamline. [...]

A General Method for Motion Compensation in X-ray Computed Tomography / Hancock, Steven (CERN) ; Biguri, Ander (Bath U.) ; Dosanjh, Manjit (CERN) ; Soleimani, Manuchehr (Bath U.)
Motion during data acquisition is a known source of error in medical tomography, resulting in blur artefacts in the regions that move. It is critical to reduce these artefacts in applications such as image-guided radiation therapy as a clearer image translates into a more accurate treatment and the sparing of healthy tissue close to a tumour site. [...]

Very high resolution optical transition radiation imaging system: Comparison between simulation and experiment / Bolzon, B (CERN ; Liverpool U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Aryshev, A (KEK, Tsukuba) ; Aumeyr, Thomas (Oxford U., JAI) ; Boogert, Stewart Takashi (Oxford U., JAI) ; Karataev, Pavel (Oxford U., JAI) ; Kruchinin, Konstantin (Oxford U., JAI) ; Lefevre, Thibaut (CERN) ; Mazzoni, Stefano (CERN) ; Nevay, Laurence James (Oxford U., JAI) ; Shevelev, M (KEK, Tsukuba) et al.
Optical transition radiation (OTR) has become a commonly used method for 2D beam imaging measurements. In the Accelerator Test Facility 2 (ATF2) at KEK, beam sizes smaller than the OTR point spread function have been measured. [...]
