“Particle therapy - future for the Baltic states?” – synthesis of the expert workshop report
/ Paļskis, Kristaps (Riga Tech. U. ; CERN) ; Korobeinikova, Erika ; Bogorada-Saukuma, Dace ; Camarda, Anna Maria (CNAO, Milan) ; Taylor, Rebecca (CERN ; Imperial Coll., London) ; Benedetto, Elena ; Mamis, Edgars (CERN ; Latvia U.) ; Radziņa, Maija ; Ērglis, Andrejs (Latvia U.) ; Adliene, Diana et al.
Background Baltic States remains one of the few regions in the Europe without a dedicated particle therapy center. An initiative since 2021 has been started by CERN Baltic Group on a novel particle therapy center development in the region in partnership with CERN NIMMS collaboration. [...]

Innovations in the Next Generation Medical Accelerators for Therapy with Ion Beams
/ Benedetto, E (Unlisted, CH) ; Vretenar, M (CERN)
Modern hadron-therapy accelerators have to provide high intensity beams for innovative dose-delivery modalities such as FLASH, pencil beams for 3D scanning, as well as multiple ions with radio-biological complementarity. They need to be compact, cheap and have a reduced energy footprint. [...]

Strongly curved super-conducting magnets: beam optics modeling and field quality
/ Benedetto, E (Unlisted, CH) ; Barna, D (Wigner RCP, Budapest) ; D’Addazio, M (Unlisted, IT) ; Maria, R De (CERN) ; Felcini, E (Unlisted, IT) ; Frisella, G (Unlisted, IT) ; Garolfi, L (Unlisted, CH ; CERN) ; Latina, A (CERN) ; Norman, H (Manchester U.) ; Oponowicz, E (CERN) et al.
Superconducting dipoles with a strong curvature (radius smaller than 2 meters, for an aperture of about 100 mm and a length of 1-3 meters) are required for applications where compactness is key, such as the synchrotron and gantry for Carbon-ion therapy developed within the European program HITRIplus.Such magnets challenge several assumptions in the field description and put to the test the range of validity of beam optics codes. In particular, the equivalence that holds for the straight magnets between the transverse multipoles description obtained from the Fourier analysis (used for magnet design and measurements) and the Taylor expansion of the vertical field component along the horizontal axis (used in beam optics) is not valid any longer.

Conceptual design of a compact synchrotron-based facility for cancer therapy and biomedical research with helium and proton beams
/ Vretenar, M (CERN) ; Angoletta, M E (CERN) ; Borburgh, J (CERN) ; Bottura, L (CERN) ; Taylor, R (CERN) ; Tranquille, G (CERN) ; Benedetto, E (Unlisted, CH) ; Torims, T (Latvia U., ISSP) ; Paļskis, K (Latvia U., ISSP) ; Sapinski, M (PSI, Villigen) et al.
Thanks to their superior dose conformality and higher radiobiological effectiveness with respect to protons, helium ions are considered as the new tool of choice in the fight against cancer using particle beams. A facility to produce helium beams at therapeutical energy can also accelerate protons, at energies permitting both standardised treatment and full body radiography, and heavier ions for treatment of shallow tumours and for research.

Slow extraction with octupoles at CERN proton synchrotron to improve extraction efficiency
/ Taylor, R (CERN ; Imperial Coll., London) ; Fraser, M (CERN) ; Arrutia, P (CERN) ; Johnson, E (CERN) ; Benedetto, E (Unlisted, CH)
The extraction inefficiency of the slow extraction process induces radioactivity in the area surrounding the electrostatic septum. Studies at the CERN Proton Synchrotron (PS) are investigating beam loss reduction techniques to improve the efficiency of the beams provided to the experiments of the East Area. [...]

Slow Extraction Techniques from Fixed Field Accelerators
/ Taylor, R (Imperial Coll., London ; CERN) ; Steinberg, A F (Manchester U. ; Melbourne U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Pasternak, J (Imperial Coll., London) ; Appleby, R B (Manchester U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Sheehy, S L (Melbourne U. ; ANSTO, Menai) ; Benedetto, E (Unlisted, CH ; CERN)
Fixed Field Accelerators are a candidate for future hadron cancer therapy facilities as their high repetition rate and large energy acceptance enables novel treatment modalities such as high dose rate FLASH. However, conventional dose delivery mechanisms are still necessary, requiring continuous beam delivery over 1--30s. [...]
