Abstract
The invention discloses a cleaning method for an ultrathin metal grid mesh used for a scanning streak tube. The cleaning method is mainly used for cleaning the ultrathin metal grid mesh of the high-speed imaging and scanning streak tube. According to the main technical scheme, the cleaning method includes the technological processes that the grid mesh is loaded, a surface is pretreated; the surface is ultrasonically cleaned; pure water rinsing is conducted; dewatering is conducted; drying is conducted; and detection is conducted. Trials of the cleaning method prove that the defects that an original cleaning method cannot be used for thoroughly removing surface dirt on the grid mesh and cannot meet technical requirements are overcome fundamentally; and surface dirt can be thoroughly removed from the cleaned grid mesh, it is also ensured that the grid mesh is free of little damage, deformation and wrinkles, and the use requirement of the scanning streak tube is completely met.
Description
technical field [0001] The invention relates to a metal surface cleaning treatment method, in particular to a cleaning method for an ultra-thin metal grid sheet of a high-speed imaging scanning stripe tube, and can also be used for cleaning treatment of similar parts of other photoelectric devices. Background technique [0002] The fringe framing camera is a nanosecond or picosecond ultra-high-speed photoelectric imaging device. Its core component, the scanning fringe tube, can simultaneously provide one-dimensional continuous time information and one-dimensional continuous spatial information. The ability to extract time information, thus providing space and time information for the study of fast, non-repetitive transient phenomena, has important applications in laser ultrashort pulses, laser nuclear fusion, magnetic confinement nuclear fusion, photochemistry, and photobiology. [0003] scanning streak tube (see figure 1 ) is composed of a photocathode 1, a single-layer mu...
