SID4 V Vacuum

Phasics is innovating by proposing the first off-the-shelf vacuum compatible wavefront sensor on the market. The SID4 Vis designed to perform wavefront measurements under high vacuum. the wavefront measurement is realized in-situ in the same condition as the experiment. Our new SID4 V vacuum wavefront sensor is also used to characterize laser beams after compression inside the compressor vessel. Finally， gas jet and plasma density are now measured as close to the target as possible.

BENEFITS: With Phasics’s unique strategy it’s now possible to correct the aberrations of every single optical element up to the target location inside the vacuum chamber.

SID4 Density software

Introduction

SID4 DENSITY software package supports the whole process to measure gas and plasma electron density. It calculates density maps from phase acquisition. It also offers various options for acquisition and data analysis.

Specifications

WORKING CONDITIONS
Application	Any axisymmetric monoatomic gas jet/plasma for inverse-Abel transform analysis
Probe source	White light (halogen)， LED， laser or fs-laser
Pressure	From 2 to 300 bars
Plasma length	Depends on the imaging system (typically 2 mm long and diameter of 0.2 mm)

SOFTWARE
Acquisition	Real Time， programmed， trigger
Settings	Wavelength， magnification， jet direction， gas type
Analysis	Density map & profiles， Symmetrization， filters

Performances such as the spatial resolution or the density resolution entirely depend on both the optical set-up (imaging system， probe source) and the injected gas (molar refractivity). Please contact us for an estimation of specifications for your set-up.

As an example， for an laser produced plasma using an Argon gas jet at working pressure between 2 and 300 bars， the lowest measured Argon density in a single shot is: 1017 particles/cm3 with a nozzle of 1.5 mm diameter.
