Mass Analyzers: Common Types

Mass Analyzers: Common Types

The quadrupole mass analyzer consists of four cylindrical metal rods arranged in a diamond carrying a DC voltage and a radio-frequency AC voltage. The motion of ions through the quadrupole depends on the field strength, causing only ions of a certain m/z to resonate successfully and strike the detector at a given field strength. Though the transmission rate for these analyzers is high, the exact elemental composition of the sample is not determined because of low resolution; however, they are...

Atomic Emission Spectroscopy: Overview

Atomic Emission Spectroscopy: Overview

Atomic emission spectroscopy (AES) is an analytical technique used to determine the elemental composition of a sample by analyzing the light emitted from excited atoms. In AES, atoms in a sample are excited to higher energy levels by thermal energy from high-temperature sources, such as plasma, arcs, or sparks. When these excited atoms return to lower energy states, they emit light at specific wavelengths characteristic of each element. The resulting atomic emission spectrum, which consists of...

Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation

Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation

Inductively coupled plasma (ICP) is the common plasma source used in atomic emission spectroscopy (AES), a technique that detects and analyzes various elements in a sample. This method is often called inductively coupled plasma atomic emission spectroscopy (ICP-AES).
There are three main types of inductively coupled plasma atomic emission spectroscopy (ICP-AES) instruments: sequential, simultaneous multichannel, and Fourier transform instruments, with the latter being less commonly used....

Thomson's e/m Experiment

Thomson's e/m Experiment

In a beam of charged particles created by a heated cathode, the particles move at different speeds. However, many applications need a beam with uniform particle speeds. An arrangement known as a velocity selector uses electric and magnetic fields to pick particles with a particular speed from the beam.
A particle with charge q, speed v, and mass m enters an area from the top, where the magnetic and electric fields are perpendicular both to the particle's motion and to one another. The magnetic...

Atomic Emission Spectroscopy: Lab

AES is a powerful analytical technique, especially effective when used with plasma sources, producing abundant spectra in characteristic emission lines. The Inductively Coupled Plasma (ICP), in particular, yields superior quantitative analytical data due to its high stability, low noise, low background, and minimal interferences under optimal experimental conditions. However, newer air-operated microwave sources are emerging as promising alternatives that could be more cost-effective than...

Atomic Fluorescence Spectroscopy

Atomic Fluorescence Spectroscopy

Atomic fluorescence spectroscopy (AFS) is an analytical technique that involves the electronic transitions of atoms in a flame, furnace, or plasma being excited by electromagnetic (EM) radiation. When these atoms absorb energy, they become excited and subsequently release energy as they return to their original state. This emitted light, or "fluorescence," is observed at a right angle to the incident beam. Both absorption and emission processes transpire at distinct wavelengths, which...

Background:

Axions and axion-like particles are hypothetical particles proposed to solve theoretical problems in physics.
Experimental searches are crucial for detecting these elusive particles and probing new physics beyond the Standard Model.

Purpose of the Study:

To present the first experimental searches for axions and axion-like particles using the Large Underground Xenon (LUX) experiment.
To set new limits on the axion-electron coupling constant (g_{Ae}) and axion mass.

Main Methods:

Utilized data collected in 2013 with an exposure of 95 live days × 118 kg from the LUX experiment.
Assumed an axioelectric interaction mechanism in xenon.
Employed a double-sided, profile likelihood ratio statistic test to analyze the data.

Main Results:

Excluded axion-electron coupling constants (g_{Ae}) greater than 3.5×10^{-12} (90% C.L.) for solar axions.
Derived upper limits on axion mass: 0.12 eV/c² (Dine-Fischler-Srednicki-Zhitnitsky model) and excluded masses above 36.6 eV/c² (Kim-Shifman-Vainshtein-Zhakharov model).
Excluded g_{Ae} > 4.2×10^{-13} for galactic axion-like particles with masses between 1-16 keV/c².

Conclusions:

These results represent the most stringent constraints to date on axion and axion-like particle interactions.
The LUX experiment has provided significant contributions to the search for these hypothetical particles.
