The influence of a supersonic projectile on a three-dimensional complex plasma is studied. Micron sized particles in a low-temperature plasma formed a large undisturbed system in the new 'Zyflex' chamber during microgravity conditions. A supersonic probe particle excited a Mach cone with Mach number M $\approx$ 1.5 - 2 and double Mach cone structure in the large weakly damped particle cloud. The speed of sound is measured with different methods and particle charge estimations are compared to…

Algorithms for Particle Detection in Complex Plasmas
Different variations of the moment method are combined with common techniques for image pre- and post-processing, and the impact of the choice of threshold parameters, including an automatic threshold detection, on synthetic data with known attributes is investigated.
Image Registration with Particles, Examplified with the Complex Plasma Laboratory PK-4 on Board the International Space Station
Two methods to combine the associated image pairs into one image are presented, namely the SimpleElastix toolkit based on comparing the mutual information and a method based on detecting the particle positions.


Mach cones in a three-dimensional complex plasma
A three-dimensional hydrodynamic model has been applied to study the Mach cones in a three-dimensional complex plasma. Numerical results for the velocity distribution of dust particles showed the
Direct measurement of the speed of sound in a complex plasma under microgravity conditions
We present a direct measurement of the speed of sound in a three-dimensional complex plasma —a room-temperature plasma that contains micrometer-sized particles as fourth component. In order to obtain
Supersonic Particle in a Low Damped Complex Plasma under Microgravity
We discuss the diagnostics of a complex plasma cloud recorded in experiments performed in the framework of the Ekoplasma project. A supersonic extra particle is used as a probe of the cloud dynamics.
Cavity dynamics and particle alignment in the wake of a supersonic projectile penetrating a dusty plasma.
The penetration of a projectile into a strongly coupled dusty plasma was studied in a radio-frequency discharge under microgravity conditions and the dynamics can be subdivided into three phases: An opening phase with fixed time scale, a closing phase whose duration is affected by the projectile speed and a phase of particle realignment in the target cloud, which persists for a long time after the closure of the cavity.

Over the limited range of speed V attained by the supersonic particles in this experiment, the angle mu of the cone was found to obey the Mach cone rule sin mu = c/V, where c is the medium's sound speed.
Measurement of the speed of sound by observation of the Mach cones in a complex plasma under microgravity conditions
We report the first observation of the Mach cones excited by a larger microparticle (projectile) moving through a cloud of smaller microparticles (dust) in a complex plasma with neon as a buffer gas
Theoretical study of laser-excited Mach cones in dusty plasmas.
A two-dimensional hydrodynamic model for a monolayer of dust particles is used to study the Mach cones excited by a moving laser beam through dusty plasmas and it is found that the compressional Mach cones exist in cases of both supersonic and subsonic excitations.
Wake-Mediated Propulsion of an Upstream Particle in Two-Dimensional Plasma Crystals.
It is shown that the nonreciprocity of the particle interaction, owing to the wake charges, is responsible for a broken symmetry of the channel that enables a persistent self-propelled motion of the extra particle.
Laser-excited mach cones in a dusty plasma crystal
Experimental studies of the formation and structure of Mach cones in a plasma crystal are presented, using a monolayer of particles interacting through a Yukawa potential, and two methods of determining the particle charge and screening distance are developed.
Observation of shear-wave Mach cones in a 2D dusty-plasma crystal.
Mach cones composed of shear waves were observed experimentally in a two-dimensional screened-Coulomb crystal and had a single-cone structure, which is explained by the almost dispersionless character ofShear waves.
