“…lengths [15][16][17][18][19] but to first approximation these equations show the velocity dependent competition in the two scattering rates. Whichever interaction occurs first, there is generally a cascade of many scattering events resulting in a larger amount of energy being deposited in the ion lattice compared to gamma-ray interactions.…”

This review discusses detector physics and Monte Carlo techniques for cryogenic, radiation detectors that utilize combined phonon and ionization readout. A general review of cryogenic phonon and charge transport is provided along with specific details of the Cryogenic Dark Matter Search detector instrumentation. In particular this review covers quasidiffusive phonon transport, which includes phonon focusing, anharmonic decay and isotope scattering. The interaction of phonons in the detector surface is discussed along with the downconversion of phonons in superconducting films. The charge transport physics include a mass tensor which results from the crystal band structure and is modeled with a Herring Vogt transformation. Charge scattering processes involve the creation of Neganov-Luke phonons. Transition-edge-sensor (TES) simulations include a full electric circuit description and all thermal processes including Joule heating, cooling to the substrate and thermal diffusion within the TES, the latter of which is necessary to model normal-superconducting phase separation. Relevant numerical constants are provided for these physical processes in germanium, silicon, aluminum and tungsten. Random number sampling methods including inverse cumulative distribution function (CDF) and rejection techniques are reviewed. To improve the efficiency of charge transport modeling, an additional second order inverse CDF method is developed here along with an efficient barycentric coordinate sampling method of electric fields. Results are provided in a manner that is convenient for use in Monte Carlo and references are provided for validation of these models. Contents

“…[12] topes and measured the broadening of their relaxation resulting from the (n,n ) nuclear recoil for varying incident neutron energies [8][9][10]. The measurements producing recoils with elastic neutron scattering may be split into two families; the first using mono-energetic neutrons incident on a target and detecting neutrons that scatter in the target at a known scattering angle, the second employ broad spectrum neutron sources and compare data with Monte Carlo simulations.…”

“…of nuclear recoils have been reported in candidate detector materials [4][5][6][7][8][9][10][11][12] (see Table I). Of the reported measurements only two [11,12], have probed recoils below one keV, both in Ge. This largely unexplored energy range is the most important to CNS searches [2,13,14].…”

“…The lowest recoil energy reported [12] made use of the nuclear recoil accompanying an (n,γ) interaction. This approach is hampered by the limited choice of γ-emitting transitions in the target material and is further complicated by additional energy deposition from secondary γ-emission.…”
