(P43) phosphor used in CCD detectors for electron microscopy," Ultramicroscopy, vol.
It is one of the most important deoxidisers suppressing pinholes in the ingot, or casting and oxysulphide
formation; it helps to control the undesirable effects of residual sulphur.
Inclusions of type 1b, which are also undeformed, have been found to be two-phase oxysulphide particles.
The spherical particle (1d, ii) observed along side the strings, is an oxysulphide inclusion whose composition is similar to the one discussed in figure 1b.
The physical instrument of the a-Si detector itself would only measure the energy deposited in the gadolinium oxysulphide
terbium-activated (Gd202:Tb) layer; no knowledge of the radiation history (i.e., the breakdown of interaction and particle type) could be gained.
For example, the imaging chain may use an image intensifier (II) that incorporates a cesium iodide (CsI) or gadolinium oxysulphide
([Gd.sub.2][O.sub.2]S:Tb) scintillator input window.
