“…For example, in the QSPA Kh-50, droplets velocities may achieve several tens of m/s [23], in GOL-3, droplets with velocities of up to several hundred m/s were detected just after the beam termination [24]. The QSPA droplet velocity estimation is undervaluing, and the GOL-3 droplet velocity estimation is overrating because of: 1) the vapor shield pressure in QSPA exceeds that in ITER [22], and the vapor shield pressure in GOL-3 is less than that in ITER; 2) in QSPA, no droplets can be detected during the irradiation and 1 ms after it [25]. The QSPA data about the droplet formation are insufficient, and the GOL-3 data are important for prediction of droplet parameters for ITER transient events.…”
