“…Errors bands for data in the right plot have been omitted for further clarity. The axis labeled relative scintillation efficiency (L e f f ) refers to a traditional normalization to 57 Co, a mixture of 122 keV (dominant) and 136 keV gammas. Note that our curves are not fits but predictions.…”

“…We omit works ( [56] for example) which define "total" light and charge yields for partial energy deposition "peaks," as these would require proper modeling of the detector in question in order to reproduce well. We also exclude older works with measurements that cannot be reconciled with more recent ones, including [57], and Voronova et al as cited in [56]. More recent experiments have benefited from technological advancements, leading to more accurate measurements.…”

NEST: a comprehensive model for scintillation yield in liquid xenon

et al. 2011

View full text Add to dashboard Cite

A comprehensive model for explaining scintillation yield in liquid xenon is introduced. We unify various definitions of work function which abound in the literature and incorporate all available data on electron recoil scintillation yield. This results in a better understanding of electron recoil, and facilitates an improved description of nuclear recoil. An incident gamma energy range of O(1 keV) to O(1 MeV) and electric fields between 0 and O(10 kV/cm) are incorporated into this heuristic model. We show results from a Geant4 implementation, but because the model has a few free parameters, implementation in any simulation package should be simple. We use a quasi-empirical approach, with an objective of improving detector calibrations and performance verification. The model will aid in the design and optimization of future detectors. This model is also easy to extend to other noble elements. In this paper we lay the foundation for an exhaustive simulation code which we call NEST (Noble Element Simulation Technique).

“…For high energy particles, 100 keV, which leave a well-defined 'long' track in the liquid, the dE/dx approach works relatively well: the higher the dE/dx value the stronger the recombination. Thus, for the low-LET ∼1 MeV electrons (dE/dx ∼1 MeV cm 2 /g) about 90% of the charge created initially can be extracted by applying a field of the order of a few kV/cm [94,150,149], while for α-particles (dE/dx ∼500 MeV cm 2 /g) a field of ∼20 kV/cm in liquid argon, or ∼80 kV/cm in liquid xenon, is required to collect about 20% of the charge [148,147]. Figure 13 on page 30 shows some of the available data on the charge yield as a function of electric field for different particles.…”

Liquid noble gas detectors for low energy particle physics

2013

View full text Add to dashboard Cite

We review the current status of liquid noble gas radiation detectors with energy threshold in the keV range, which are of interest for direct dark matter searches, measurement of coherent neutrino scattering and other low energy particle physics experiments. Emphasis is given to the operation principles and the most important instrumentation aspects of these detectors, principally of those operated in the double-phase mode. Recent technological advances and relevant developments in photon detection and charge readout are discussed in the context of their applicability to those experiments.

“…The simple design of pulse ionization chambers (PICs) with a grid, their radiation hardness, high energy resolution, wide dynamic range of induced charge measurements (up to 10 7 ), the possibility of obtaining, along with the anode signal, the auxiliary logical signals from the other electrodes, and simple relationship between the ionization in the volume and these signals determine the field of application for these detectors [1][2][3][4].…”

Improving the energy resolution in grid ionization chambers by eliminating the induction effect

et al. 2013

View full text Add to dashboard Cite

The dependence of the charge induced at the anode of a flat grid ionization chamber on the grid shielding inefficiency and the mean free path of electrons before their capture by an electronegative impurity is analyzed. The cases of point ionization and ionization in the form of a track of a charge particle from the source located at the cathode are considered. It is shown by calculation and corroborated by experiment that the contribution of the induction effect to the total energy resolution of chambers with a large grid pitch is substantially suppressed, which helps simplify the grid manufacturing technology.
