Induced catcher current in the walls of catcher cavity is the induced form current in catcher's cavity that results from the interaction between an electron beam and an electromagnetic wave in a resonant cavity system.
The calculator uses the formula:
Where:
Explanation: The induced current is directly proportional to the arriving current and the beam coupling coefficient, which measures the interaction efficiency between the electron beam and the electromagnetic wave.
Details: Accurate calculation of induced catcher current is crucial for designing and optimizing microwave tubes, klystrons, and other resonant cavity devices where efficient energy transfer between electron beams and electromagnetic fields is essential.
Tips: Enter the current arriving at the catcher cavity gap in amperes and the beam coupling coefficient (a value between 0 and 1). Both values must be valid positive numbers.
Q1: What is the beam coupling coefficient?
A: The beam coupling coefficient is a measure of the interaction between an electron beam and an electromagnetic wave in a resonant cavity, typically ranging from 0 to 1.
Q2: What are typical values for the beam coupling coefficient?
A: Typical values range from 0.5 to 0.95, depending on the cavity design and operating conditions.
Q3: How is the current arriving at the catcher cavity gap measured?
A: This current is typically measured using current probes or calculated based on the electron beam parameters and the device geometry.
Q4: What factors affect the beam coupling coefficient?
A: The coefficient is influenced by cavity geometry, beam velocity, operating frequency, and the quality of beam-cavity alignment.
Q5: Can this formula be used for all types of resonant cavities?
A: While the basic principle applies to many cavity types, specific applications may require modified formulas to account for particular cavity geometries and operating conditions.
