Cavity design for high-frequency axion dark matter .

the cavity design using two tuning rods does not provide for successful scanning above ∼1.5 GHz. Increasing the diameter of the tuning rods can drive the TM 0n0 frequencies above 1.5 GHz, but the form factor (C) of the modes and scanning range of the cavity decrease significantly.

Resonator - Wikipedia

Cavity resonators. A cavity resonator is a hollow closed conductor such as a metal box or a cavity within a metal block, containing electromagnetic waves (radio waves) reflecting back and forth between the cavity's walls. When a source of radio waves at one of the cavity's resonant frequencies is applied,...

3 Moulding Considerations - dupont

As a rule, the outside diameter of a boss should be 2 to 3 times the hole diameter to ensure adequate strength. The same principles used in designing ribs pertain to designing bosses, that is, heavy sections should be avoided to prevent the formation of voids or sink marks and cycle time penalty. Less good design of bosses can lead to sink marks (or even

Design of a Cylindrical Cavity Resonator for Measurements ...

The design and measurements will be presented in both simulations and practice. With 1.2GHz cavity resonator, in the simulations, the dielectric permittivity for Teflon is measured as 2.09-0.0023i and 2.12-0.0116 in copper cavity and ferromagnetic cavity. Finally the sample is measured as 3.83-0.12i in practice.

Principle Of Gate Design - PIM plastic mold company

Dec 06, 2017 · Gate is a passage way from the subrunner to the mold cavity,and its cross-section is the smallest and shortest part in the injection system. Position,number, shape and size of the gate have a direct impact on the quality and the appearance of the product, and therefore, in the design process attention is required for gate style.

Plant Engineering | Understanding progressive cavity pumps

Oct 01, 2000 · The displacement of a progressive cavity pump depends on three design features: Rotor diameter. Rotor eccentricity. Stator pitch. The pump's pressure rating depends on the number of stages. By repeating the identical, single-helical con-figuration, increasing the length of the stator and rotor increases the number of stages (Fig. 2).

PLASTICS PART DESIGN and MOLDABILITY

Part design obviously has to be influenced by the intricacies of the process. Filling phase of the process is influenced by type of gate, location of gate, number of gates, size of gate (also dependent on material viscosity). Gate should be located at such a position from where flow path to thickness ratio (flow ratio)is constant in all direction.
