TiaRA : transfer reaction array Strip detector box to fit inside EXOGAM Position sensitive, resistive strips Forward (& back) angle annular strips Design aimed at coincidence transfer work Also suits coulex and fusion-evaporation New development, subject of new grant bid

Light particle in strip array, record angle and energy Heavier particle or sequential breakup fragment in segmented zero degree detector Gamma ray(s) in EXOGAM, energy gives accurate excitation energy, even when using quite thick target

Light charged particles in strip array, record angle and energy for channel selection and Doppler correction Evaporation residue and forward scattered beam continues beyond view of gamma array Gamma ray(s) in EXOGAM n p  p Energy loss in Si gives particle ID

Scattered beam particles in strip array, measuring angle and energy for multi-step excitation in large angle scattering, and also allowing Doppler correction Forward angle scattering can be identified beyond the array, e.g. using MEGHA, for low states Gamma ray(s) in EXOGAM
