abstract = {An irreversible response of inorganic scintillators to
intense soft x-ray laser radiation was investigated at the
FLASH (Free-electron LASer in Hamburg) facility. Three ionic
crystals, namely, Ce:YAG (cerium-doped yttrium aluminum
garnet), PbWO4 (lead tungstate), and ZnO (zinc oxide), were
exposed to single 4.6 nm ultra-short laser pulses of
variable pulse energy (up to 12 μJ) under normal incidence
conditions with tight focus. Damaged areas produced with
various levels of pulse fluences, were analyzed on the
surface of irradiated samples using differential
interference contrast (DIC) and atomic force microscopy
(AFM). The effective beam area of 22.2 ± 2.2 μm2 was
determined by means of the ablation imprints method with the
use of poly(methyl methacrylate) - PMMA. Applied to the
three inorganic materials, this procedure gave almost the
same values of an effective area. The single-shot damage
threshold fluence was determined for each of these inorganic
materials. The Ce:YAG sample seems to be the most radiation
resistant under the given irradiation conditions, its damage
threshold was determined to be as high as 660.8 ± 71.2
mJ/cm2. Contrary to that, the PbWO4 sample exhibited the
lowest radiation resistance with a threshold fluence of 62.6
± 11.9 mJ/cm2. The threshold for ZnO was found to be 167.8
± 30.8 mJ/cm2. Both interaction and material
characteristics responsible for the damage threshold
difference are discussed in the article},
