Development of an Ion Emitter with Hollow Cold Cathode
Ion physics forms the basis for numerous modern technologies and research directions such as microelectronics, material research, analytics or high-energy physics. The reason for the broad range applications of ion physics lies in the ions characteristics: -The ions possess a mass, which makes a direct energy transfer possible to the solid atoms (flexible energy transmission); -The velocity of ...
متن کاملCharacteristics of a cold cathode electron source combined with secondary electron emission in a FED
In electron beam devices, the voltage applied to the cathode (w.r.t. grid voltage) provides the initial energy for the electrons. Based on the type of electron emission, the electron sources are (mainly) classified into thermionic cathodes and cold cathodes. The power consumption of a cold cathode is smaller than that of a thermionic cathode. The delay time of the electron emission from a cold ...
متن کاملDormant Cathode Erosion in a Multiple-Cathode Gridded Ion Thruster
A rectangular gridded ion thruster discharge chamber is investigated for operation with multiple discharge cathode assemblies. The multiple-cathode approach attempts to increase thruster throughput and lifetime by operating three discharge cathode assemblies sequentially, possibly providing a threefold increase in discharge chamber life. Previous multiple-cathode electric propulsion devices, su...
متن کاملLaser-cooled ion plasmas in Penning traps¶
A laser-cooled ion plasma in a Penning trap provides a rigorous realization of a strongly coupled one-component plasma. After a brief review of the crystal structures that have been observed in Penning traps, we summarize two recent experiments. First we describe careful measurements of the stability of the plasma rotation which is controlled by a rotating electric field. We then discuss the ex...
متن کاملNovel Designs for Penning Ion traps
We present a number of alternative designs for Penning ion traps suitable for quantum information processing (QIP) applications with atomic ions. The first trap design is a simple array of long straight wires which allows easy optical access. A prototype of this trap has been built to trap Ca + and a simple electronic detection scheme has been employed to demonstrate the operation of the trap. ...
