Determination of Charge State, Energy and Angular Distributions of Tin Ions Emitted from Laser Produced Plasma Based Euv Sources. Determination of Charge State, Energy and Angular Distributions of Tin Ions Emitted from Laser Produced Plasma Based Euv Sources
We have performed time of flight (TOF) analysis to determine the intensity of ion distribution from tin based plasma for a range of charged tin ions (Sn–Sn). A Nd:YAG laser operating at 1064 nm with a full width at half maximum pulse duration of 5.2 ns was used to create the plasma under vacuum with a base pressure of 10−6 Torr. The plasma formation occurred on a custom made optical system, whi...
متن کاملCharacteristics of Ions Emission from Ultrashort Laser Produced Plasma
The dynamic characteristics of the ions emitted from ultrashort laser interaction with materials were studied. A series of successive experiments were conducted for six different elements (C, Al, Cu, Mo, Gd, and W) using 40 fs, 800 nm Ti: Sapphire laser. Time-of-flight (TOF) ion profile was analyzed and charge emission dependencies were investigated. The effects of incident laser interaction wi...
متن کاملAngular emission of ions and mass deposition from femtosecond and nanosecond laser-produced plasmas
We investigated the angular distribution of ions and atoms emanating from femtoand nanosecond laser-produced metal plasmas under similar laser fluence conditions. For producing plasmas, aluminum targets are ablated in vacuum employing pulses from a Ti:Sapphire ultrafast laser (40 fs, 800 nm) and an Nd:YAG laser (6 ns, 1064 nm). The angular distribution of ion emission as well as the kinetic ene...
متن کاملAngular distribution of debris from CO2 and YAG laser- produced tin plasmas
We investigated the angular dependence of atomic and ionic debris from CO2 and YAG laser-produced tin plasmas. Several diagnostic techniques were employed for this study including a Faraday cup, witness plates and subsequent x-ray photoelectron spectroscopic analysis, optical emission spectroscopy etc. It was found that the debris emission from the Nd:YAG laser-produced plasmas fell sharply fro...
متن کاملRadiation properties and hydrodynamics evolution of highly charged ions in laser-produced silicon plasma.
We present a simplified radiation hydrodynamic model based on the fluid dynamic equations and the radiative transfer equation, which can be used to investigate the radiation properties and dynamics evolution of highly charged ions in a laser-produced plasma in vacuum. The outputs of the model consist of the evolution of the electron temperature, atom, and ion density, and the temporal and spati...
