“…Since h m is of order tens of microns, but k RT /6 $ 1.5 mm, the instability cannot produce significant droplet expulsion and would instead be expected to lead to the formation of a ''wavy'' profile of the resolidified surface with wavelength on the order of a few mm. This is in fact precisely what was found in photon flash exposure tests of SS samples in the TRINITI QSPA facility [8]. In this case, the event numbers were far lower ($150) than in the e-beam tests described here in Section 3.1 and in addition were created by uniform, simultaneous transient erosion of small disc samples (as opposed to e-beam scanning).…”

“…At an F HF $ 13 MJ m À2 s À1/2 , SS will melt, compared with $28 MJ m À2 s À1/2 for Be [8]. It is therefore clear that TQ photon flash energy transients associated with MGI mitigated disruptions at full performance in ITER can easily melt SS surfaces.…”

“…При этом расчёты, приведённые в [12], показывают, что п о-сле воздействия с тепловой нагрузкой Q = 0,5 МДж/м 2 расплав нержавеющей стали полностью за-стывает за время ~200 мкс. Поэтому для дальнейших оценок Δt принималось равным времени плаз-менного воздействия (~600 мкс).…”

“…In the present work QSPA-T was used for providing photonic heat loads relevant to ITER mitigated disruption. On QSPA-T powerful photonic radiation is generated by braking an argon-doped hydrogen plasma flow on a solid target [2]. A significant part of the plasma energy transforms to photonic energy as a result of this process.…”

“…The previous stage of this investigation [2] was concerned with the behavior of ITER-grade stainless steel (316L(N)-IG) on the diagnostic first wall (DFW) under photonic heat loads. The primary attention of the present work is focused on the following points: (a) bulk beryllium (Be) performance under photon flash heating; (b) behavior of the reduced-activation ferritic-martensitic steels (RAFMS) under photon flash heat loads; (c) behavior of the deposited erosion products of the plasma facing materials (tungsten, beryllium, and graphite based materials) under photonic radiation of the plasma.…”
