Problems solved by technology

[0002] In the existing modern physics experiments in colleges and universities, the electron paramagnetic resonance experiment is a compulsory item for the group experiment of students. Generally, the laboratory has multiple sets, and each set of instruments costs nearly 20,000 yuan, but a set of instruments can only do one experiment, and only use it every year. Less than a month, resulting in a large waste

Abstract

A comprehensive microwave experiment device is provided, which comprises a microwave oscillator, an isolator, a crystal wave detector, an oscillograph, a microwave cymometer, a resonant cavity, a electromagnet and a shorting piston linked in sequence. The device is characterized in that: the resonant cavity and the shorting piston can be replaced by the standing wave measuring line, total reflection copperplate and multi-aperture copper reflector, and student experiments of three modern physics projects on electron paramagnetic resonance, light velocity measurement and the research on microwave characteristics can be carried out.

Description

Technical field [0001] The invention relates to a microwave comprehensive experiment device, in particular to a student experiment instrument capable of carrying out three items of electron paramagnetic resonance, light velocity measurement and microwave characteristic research. Background technique [0002] In the existing modern physics experiments in colleges and universities, the electron paramagnetic resonance experiment is a compulsory item for the student group experiment. Generally, the laboratory has multiple sets, and each set of instruments costs nearly 20,000 yuan, but a set of instruments can only do one experiment, and only use it every year. In less than a month, it caused a lot of waste. Contents of the invention [0003] The invention provides a microwave comprehensive student experiment instrument, which can not only carry out electron paramagnetic resonance experiments, but also carry out two student experiments of microwave characteristic research and a...
