Particle distributions in collisionless magnetic reconnection: An implicit Particle-In-Cell (PIC) description

Description: Evidence from magnetospheric and solar flare research supports the belief that collisionless magnetic reconnection can proceed on the Alfven-wave crossing timescale. Reconnection behavior that occurs this rapidly in collisionless plasmas is not well understood because underlying mechanisms depend on the details of the ion and electron distributions in the vicinity of the emerging X-points. We use the direct implicit Particle-In-Cell (PIC) code AVANTI to study the details of these distributions … more

Process of making cryogenically cooled high thermal performance crystal optics

Description: A method for constructing a cooled optic wherein one or more cavities are milled, drilled or formed using casting or ultrasound laser machining techniques in a single crystal base and filled with porous material having high thermal conductivity at cryogenic temperatures. A non-machined strain-free single crystal can be bonded to the base to produce superior optics. During operation of the cooled optic, N{sub 2} is pumped through the porous material at a sub-cooled cryogenic inlet temperature an… more

[1990 NTIEVA Summer Institute Questionnaire Responses]

Description: A paper that documents the answers from the North Texas Institute for Educators on the Visual Arts 1990 Summer Institute questionnaire. The pre-assessment questions were answered on a scale from 'Excellent, Good, Fair, Poor, Invalid' and varied from person to persons opinion on the certain questions. Such questions focused on how the respondents felt about issues within art education. The post-assessment questions allowed respondents to write down their full opinion to 3 questions and give comm… more

Reduction of multielement mass spectra

Description: Even though the spectra obtained by inductively coupled plasma source spectrometry (ICP-MS) are relatively simple, their interpretation can be complicated by the presence of molecular and isobaric interferants. To the extent that isotopic abundances are known and constant, one can treat observed spectra as sums of known components. A linear decomposition approach for determining the concentrations of the components in a spectrum and correctly propagating uncertainties is presented. This techniq… more
