1-Inch Saticon for high-definition color television cameras

Live X-Ray Topography and Crystal Growth of Silicon

“…47) The application to X-ray imaging depended upon whether the layer thickness could be increased sufficiently to absorb incident X-rays without degradation of resolution. For example, to keep R I at the same level as in the case of the PbO tube, q must be 0.7 with ε = 6 µm even for ν p = 10 7 photons·s −1 ·mm −2 using SR.…”

“…To improve the resolution, the following characteristics are required of the scanning electron beam. 47) (1) The electron emission area of the cathode should be as small as possible, provided that a sufficient beam current is supplied, ideally, a point-emission source with an infinite current density. (2) For a uniform resolution over the entire scanned area, the beam divergence angle should be minimized.…”

“…47) The resolution of the tube is represented by the modulation transfer function in comparison with that of the conventional tubes in Fig. 6.…”

X-ray position-sensitive detectors

“…If and when better high-gain image intensifiers become available a better choice may be found in tubes like the Saticon (Goto, Isozaki, Shidara, Maruyama, Hirai & Fujita, 1974;Shidara, Goto, Maruyama, Hirai & Nonaka, 1981) whose diode gun gives them a superior resolution (Isozaki, Kumada, Okude, Ogusu & Goto, 1981) and which have superior 'lag' or 'sticking' performance, that is a short 'memory' for previous high-intensity patterns to which they have been exposed (Shidara, Tanioka, Hirai & Nonaka, 1985).…”
