(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-
