Laser sealing cutting system for gaseous tritium light source glass pipe

Abstract

The invention relates to a laser sealing cutting system for a gaseous tritium light source glass pipe, wherein the laser sealing cutting system comprises a clamping system and a laser system, the clamping system drives a gaseous tritium light source glass pipe to rotate and move, and the laser system performs sealing cutting on the gaseous tritium light source glass pipe. According to the presentinvention, the uniform and optimal distribution of the laser energy on both sides of the sealing cutting glass can be ensured through the controlled laser technology, the stress field is generated onthe surface of the rotating sealing glass pipe, such that the glass in the light spot area achieves the temperature of higher than the softening temperature; and through the translation of the glass pipe, the sealing cutting of the tritium light source is achieved, such that the effects of flat glass pipe sealing cutting surface, precise size and the like can be achieved.

Description

technical field [0001] The invention relates to the field of radioactivity, in particular to a gaseous tritium light source glass tube laser sealing and cutting system. Background technique [0002] The gaseous tritium light source is a self-excited weak light source that does not require external energy. It is a luminous body formed by coating the inner wall of a glass tube with a phosphor coating, then filling it with tritium gas and sealing it. The principle is to use the fluorescent coating to absorb the energy-carrying β-ray energy produced by the decay of radioactive isotope tritium and then be excited, and emit photons to emit light during the de-excitation process. [0003] The preparation process of gaseous tritium light source includes structural design, phosphor coating, tritium filling and sealing, among which sealing technology is the most critical point, and the effect of sealing directly affects the quality of gaseous tritium light source preparation.
