      abstract     = {The toroidal magnetized system (TOMAS) plasma facility aims
                      at complementary research on wall conditioning methods,
                      plasma production and plasma–surface interaction studies.
                      This paper explores for the first time the parameters in
                      helium electron-cyclotron resonance (ECR) plasma and
                      combined ECR + radio-frequency (RF) discharges in TOMAS. The
                      ECR discharge in this work, at 2.45 GHz and 87.6 mT, is the
                      main one for creating and maintaining the plasma, while the
                      addition of RF power at 25 MHz allows to broaden the
                      achievable electron temperature and density at a given gas
                      flow, as evidenced by triple Langmuir probe measurements.
                      This effect of the combined ECR + RF discharge provides
                      flexibility to study particular aspects of wall conditioning
                      techniques relevant to larger devices, or to approach plasma
                      conditions relevant to fusion edge plasmas for particular
                      surface interaction studies},
