Simulation studies for characterizing ultrashort bunches using novel polarizable X-band transverse deflection structures

Transverse Multibunch Instabilities for Non-Rigid Bunches

In this paper, we present a method for computing growth rates and frequency shifts of a beam containing multiple non-rigid bunches. With this approach, we calculate non-rigid multibunch effects which can impact phenomena which are traditionally treated as single-bunch effects, such as the transverse mode-coupling instability. This approach is important for high current storage rings such as PEP...

Simulation of Dark Currents in X-band Accelerator Structures

Design and Simulation of an X Band LC VCO

In this paper, a systematic method for the circuit parameters design of a monolithic LC Voltage Controlled Oscillator (VCO) is reported. The method is based on the negative resistance generation technique. As a result, a VCO has been designed in 0.18um CMOS technology using a conventional VCO structure to obtain the optimum values for the phase noise and power consumption. The simulation result...

Simulation and Derivation of Deflection Equation for Suspended Diaphragm for MEMS Application Using Kirchhoff-Love Theory

In this paper, using theory of sheets, the deflection of suspended diaphragm has been obtained under uniform and circular loading. This type of diaphragm, unlike other diaphragms, has a central support which is recommended to be used in MEMS applications. The relationship between diaphragm deflection and static analysis of this diaphragm enjoys a great significance in investigating and understa...

Transverse instabilities for multiple nonrigid bunches in a storage ring.

We describe a method for computing eigenfrequencies for a system consisting of several highly relativistic bunches of charged particles circulating in a storage ring. The bunches are treated as nonrigid, smooth distributions of charge. A bunch feels forces due to elds induced in the vacuum chamber by the dipole line density of itself and other bunches. It also feels forces due to magnets design...
