Ring images

Figure 3. a) Disclinations in an otherwise smooth nematic texture of PBT in MSA b) Ring images observed on warming a nematic PBT solution see text. The large grid spacing is 80/im. 

Figure 13. Dark-field, 0.36-nm ring image showing domains (bright spots)...

Flight system (TOF), a Ring Imaging Cerenkov (RICH) and an Electromagnetic Calorimeter (ECAL) (Figure 1). 

Figure 28.9. Schematic view of a ring image Cherenkov counter using silica aerogel blocks.

Figure 28.10. Ring image of Cherenkov light radiated by 3.5 GeV/c negative pions in the TMSA of n = 1.015 and 50 mm thick observed by an image intensifler on which the Cherenkov light was focused by a concave mirror.

RICH counter A ring imaging Cerenkov counter. When a high energy physics particles travels inside an aerogel, a radiation is emitted in a direction located on a cone which is observable as a ring... 

Fig. 34.17 Self-assembled Co NP ring imaged by brightfield TEM (center) and by off-axis electron holography (top) bar = 50 nm. The latter reveals bistable flux-closure (FC) states, polarized either CW (/e ) or CCW (right). FC polarization can be switched by applying an out-of-plane magnetic pulse with a peak strength of 2-4 kOe. Line-bond representations for the Co NP ring and FC states are shown below for clarity [40] (Reprinted with permission from the Royal Society of Chemistry)...

Recent de elopments on FAST RICH comitcns have b( cn discussed at the Workshop on Ring Imaging Detectors, Bari, Italy, June (1993).
