### Investigation of Radiation from Heavy Ion Interactions with HECTOR and BaF2 Array ###

This study explores the time spectra and energy deposition of radiation produced during interactions of a 132Xe beam at 150 MeV/u with a HECTOR array and new Pb-brick wall setup. We analyze BaF2 time spectra for multiple angles (90° and 142°) focusing on neutron and gamma radiation signatures. Results indicate prompt gamma radiation originating from the beam line, influenced by target thickness and heavy ion interactions. Additional insights into early and late gamma radiation components and energy characteristics of Kr-like light fragments are also discussed. ###

  3. New Pb-brick wall upstream of the BaF2 HECTOR array

  4. 100 MeV/u 84Kr beam 142o 90o BaF time spectra with new Pb-brick wall for thick, thin target and empty frame

  5. Hector time spectra (100 MeV/u 84Kr beam) 142o 142o 142o 90o 142o 142o 142o Floor Tot

  6. Energy deposit in MUSIC (100 MeV/u 84Kr) Kr-like Light fragments

  7. Hector time gated by Hector energy (no Doppler correction yet!) 1-2 MeV 2-4 MeV 8-20 MeV 4-8 MeV

  8. HECTOR times from the radioactive beam run

  9. Prompt radiation from target, increasing with the target thickness Early gamma radiation (5ns), coming from the beam line, caused by light particles ranging to very high energies (0-20 MeV) Late gamma radiation (8-12ns) neutrons?
