The high power test model of biperiodic L-support diskand-washer was fabricated. Among some trouble in the fabrication, the main one was a vacuum leak in a brazing process. The repair test of the leak showed a good result; four units were recovered out of five leak units (recover rate 80%). While an accelerating mode frequency was tuned at an operating frequency of 2857 MHz by squeezing method,...
The 2.5 MeV injector for the Spallation Neutron Source is currently under construction at LBNL, which includes a 2.5 MeV high power, high duty factor four vane RFQ made of four modules. Transverse mode stabilization is obtained through a series of cross coupling rods. Each of the four RFQ modules is equipped with twenty fixed tuners, two active power and two vacuum ports. Fine frequency tuning ...

The realization of bimetallic structures is one the major challenges manufacturing industry, to this aim different technologies are employed, among these vacuum brazing presents some advantages: technology, in fact, relatively easy use and relative low temperature process time avoid formation brittle intermetallics thermally affected zones. An application technology regenerative thrust chamber ...
The research aims to address the physically loading task and quality and productivity problems in the brazing of coils of air-handler units. Eight operators participated in two intervention studies conducted in a factory in Malaysia to compare the status quo brazing with (1) the use of a new twin-brazing torch that replaced the single-brazing gun and (2) brazing in a sitting position. The outco...
This paper briefly describes the development process of sealing technology for vacuum interrupter, analyze main characteristics each stage and difficulties in realizing one-time sealing. Five design schemes are put forward to achieve complete sealing, brazing tests were carried out according scheme. The test samples dissected analyzed, article it contrastive analysis. contact structure was chos...
The joining of macroscopic films of vertically aligned multiwalled carbon nanotubes (CNTs) to titanium substrates is demonstrated by active vacuum brazing at 820 °C with a Ag-Cu-Ti alloy and at 880 °C with a Cu-Sn-Ti-Zr alloy. The brazing methodology was elaborated in order to enable the production of highly electrically and thermally conductive CNT/metal substrate contacts. The interfacial ele...
