Pellet injectors developed at the PELIN laboratory for international projects

New injectors for steady state fusion plasma refuelling by solid hydrogen isotope pellets and an injector of impurity pellets encapsulated into hydrogen shells for particle transport diagnostics have been designed at the PELIN Laboratory, a branch of the PELIN, Inc. (Canada), to meet requirements of LHD, TORE SUPRA, and ITER. A review of the injector designs and results obtained to date is presented.
