  • Comparisons of the plasma ion flow speed measurements from Mach probes and laser induced fluorescence were performed in the Controlled Shear Decorrelation Experiment. We show the presence of the probe causes a low density geometric shadow downstream of the probe that affects the current density collected by the probe in collisional plasmas if the ion-neutral mean free path is shorter than the probe shadow length, L{sub g} = w{sup 2} V{sub drift}/D{sub ⊥}, resulting in erroneous Mach numbers. We then present a simple correction term that provides the corrected Mach number from probe data when the sound speed, ion-neutral mean free path,more » and perpendicular diffusion coefficient of the plasma are known. The probe shadow effect must be taken into account whenever the ion-neutral mean free path is on the order of the probe shadow length in linear devices and the open-field line region of fusion devices.« less
  • A practical formula for Mach number probe diagnostics in unmagnetized and weakly magnetized plasmas is proposed. The unmagnetized theoretical models are modified so as to make them applicable to the different shapes of Mach number probes by including the broadening of the collection angle and are extended to the weakly magnetized case. The calculated Mach numbers based on the modified expression show good agreement with each other regardless of the probe shape geometry, and are revealed to be consistent with the spectroscopic results. Applicability of the modified expression to the supersonic flow when using the Hutchinson's model and in themore » existence of the multidirectional flows is numerically examined.« less
  • We investigate the potential power of the Cosmic Mach Number (CMN), which is the ratio between the mean velocity and the velocity dispersion of galaxies as a function of cosmic scales, to constrain cosmologies. We first measure the CMN from 4 catalogs of galaxy peculiar velocity surveys at low redshift (z element of [0.002,0.03]), and use them to contrast cosmological models. Overall, current data is consistent with the WMAP7 ΛCDM model. We find that the CMN is highly sensitive to the growth of structure on scales k element of [0.01,0.1] h/Mpc in Fourier space. Therefore, modified gravity models, and modelsmore » with massive neutrinos, in which the structure growth generically deviates from that of the ΛCDM model in a scale-dependent way, can be well differentiated from the ΛCDM model by using future CMN data.« less
  • Experimental evidence is presented for three probe-size effects which influence the interpretation of Langmuir probe measurements in tokamak scrape-off plasmas. Small probes can give erroneously high values of plasma density. Large probes can only measure reliably the average energy of the high energy tail of the electron distribution. Insertion of a large probe into the scrape-off plasma can strongly disturb the plasma necessitating special analysis procedures for recovery of the unperturbed plasma characteristics.
  • We have installed and operated a reciprocating Langmuir/Mach probe to simultaneously measure parallel and perpendicular plasma flow profiles along with density, temperature, floating potential profiles, and fluctuating parameters such as fluctuation driven particle flux and wave number on a single shot. Plasma facing components are made from boron nitride and the probe tips are 1-mm-diam carbon cylinders. The Mach probe, designed following the Gundestrup model, has 12 probes arranged in a circular array. Four Langmuir probes mounted at the front of the Mach probe array measure floating potential, ion saturation current, and temperature. The perpendicular flow velocity measurements reduced frommore » the Mach probe array compare well with the phase velocity measured from the proud Langmuir probes and the E{sub r}{times}B poloidal rotation. {copyright} {ital 1997 American Institute of Physics.}« less
