“…The TSC [33] and PEST-II [34] codes are used in these calculations, for the baseline case producing W L = 1 MW m −2 , at a density n e = 0.69 × 10 20 m −3 and E NB = 110 kV D 0 . TFTR-type positive ion beam system, upgraded to steady state operation [35], is assumed.…”

“…Princeton studies have long determined the needed modifications to the TFTR neutral beams and concluded that systems could be capable of reaching 1000 s pulses with a high degree of confidence. 34 Physics challenges include demonstration of performance at full plasma parameters, T e in particular. Scaling based on existing achievements would generate 0.3 MW/m 2 of neutron flux.…”

“…The relatively moderate E NB determined in Section 5 suggests that present-day positive-ion (35) and negative-ion (46) (47) NBI techniques need to be extended to steady state operations. However, the engineering science knowledge base for the water-cooled, single-turn, normal conducting center leg of the TF coil is needed and uniquely important to CTF.…”

“…The modest plasma density in this case also allowed 〈T i 〉/〈T e 〉 > 2, leading to an apparent enhancement of H 98 to ≥ 1.5 without changing H 98e and H 98i . The required E NB of ≤ 160 kV will permit the use of the TFTR-type positive-ion NBI system (35) . The modest density further leads to a substantial level of beam-plasma fusion fraction in the range of 30-40%.…”
