Abstract: Disclosed are a special tooling and method for electron beam welding of a cavity body and a beam tube of a superconducting niobium cavity. The special tooling includes a first clamping device for fixing a flange and a second clamping device for fixing a semi-cavity body, wherein the first clamping device and the second clamping device are fixedly connected. A pressing ring of the first clamping device is disposed around a beam tube of a superconducting niobium cavity and cooperates with a base plate to clamp and fix the flange. The second clamping device includes clamping arms evenly distributed along a circumference of the semi-cavity body, and each clamping arm includes a second pressing plate axially disposed along the beam tube and a pressing block that is disposed on an end portion of the second pressing plate and fixes an edge of the semi-cavity body.

Abstract: Systems, devices, and methods are provided for all-optical reconfigurable activation devices for realizing various activations functions having normalized output power. The device and systems disclosed herein include an interferometer comprising a first branch formed of a first waveguide and a second branch formed of a second waveguide. A resonator cavity is coupled to the second first waveguide and at least one phase-shift mechanism is coupled to one of the second waveguide and the resonator cavity. The at least one phase-shift mechanism is configured to control biases of the interferometer to achieve a desired activation function at an output of the interferometer, and an optical amplification mechanism is coupled to the output of the interferometer and configured to add optical gain to the desired activation function.

Abstract: The application relates to a smart cabinet. The smart cabinet includes a cabinet body, a moving module, a controlling module and an assisting module. The moving module is positioned in the cabinet body; the controlling module is connected to the moving module. The moving module includes a base, a guiding wheel group disposed on the base, a plurality of drivers pivotally connected with the guiding wheel group, and a manipulator disposed on the base. The controlling module includes an input control unit, a guiding rope, and a pulley group. The input control module is electrically connected with the drivers and the manipulator. The pulley group includes a plurality of pulleys defining a movement range for the moving module. The assisting module includes a rope retractor and a sensor electrically coupled to the rope retractor. Two ends of the guiding rope are coupled to the rope retractor.
