(c) Single-element encapsulated mercury-cadmium-telluride (HgCdTe) uncooled (295K ambient temperature operation) photo-electromagnetic (pem) or photo-conductive (pc) mode photo detectors with a peak sensitivity at a wavelength shorter than 11 000 nanometers.
Photomultiplier tubes, as follows——
(a) For which the maximum sensitivity occurs at wavelengths shorter than 300 nanometres,
Note:
Photomultiplier tubes specially designed for use in spectrophotometry having a peak sensitivity at a wavelength shorter than 300 nanometres are not covered by this sub-item.
(For photosensitive components, see Item IL 1548.)
(b) Having an anode pulse rise time of less than 1 nanosecond;
(c) Those which contain microchannel-plate electron multipliers.
Notes: 1.
Not used.
2. For microchannel-plate electron multipliers, see IL 1556.
Flash discharge type X-ray systems, including tubes, having all of the following characteristics-
(a) Peak power greater than 500 MW;
(b) Output voltage greater than 500 kV;
(c) Pulse width less than 0.2 microsecond.
Electron tubes, as follows, and specially designed components therefor-
(a) Electron tubes for image conversion or intensification, incorporating:
(1) Fibre-optic face-plates covered by Item IL 1556 (a);
(2) Microchannel-plate electron multipliers; or
(3) Gallium arsenide or other epitaxially grown semiconductor photocathodes covered by Item IL 1556 (c);
Note:
Nothing in this subitem shall be construed as sanctioning the export of technology for image intensifiers or converters incorporating fibre-optic face-plates or micro-channel-plate electron multipliers, or electron tubes for cameras incorporating such intensifiers converters.
(b) Electron tubes for television/video cameras:
(1) Incorporating fibre-optic face-plates covered by Item IL 1556 (a);
(2) Incorporating microchannel-plate electron multipliers; or
(3) Coupled with electron tubes covered by (a) above;
(c) Ruggedised electron tubes for television/video cameras having a maximum length-to-bulb diameter ratio of 5:1 or less.
Notes:
1. This Item does not cover:
(a) Commercial standard television/video camera tubes not incorporating fibre-optic face-plates covered by Item IL 1556 (a); or
(b) Commercial standard X-ray amplifier tubes.
