QUANTITATIVE EVALUATION OF BEAM LOSS BASED ON RADIATION DETECTION IN HIGH-DUTY BEAM COMMISSIONING OF LIPAC RFQ
No full textUsing the LIPAc deuteron accelerator, beam loss characteristics were quantitatively assessed using multiple radiation measurement techniques. Elevated dose rates and isotope production at the interface between the MEBT Extension Line (MEL) and the HEBT indicate significant losses of high-energy core particles. In contrast, HPGe spectroscopy and energy-dependent calculations confirmed that halo particles lost at the HEBT magnet had lower deuteron energies than core particles. Activation foil data further validated beam losses of core and halo particles. These findings highlight the effectiveness of multi-radiation diagnostics in characterizing beam loss and enhancing radiation safety in the accelerator environment.conference pape
