Spatial Profile of Neutral Temperature Measurement in Aditya-U Tokamak Plasmas
No full textThe spatial profile of neutral hydrogen temperatures in Aditya-U tokamak plasma has been estimated from the spatial profile of the Hα spectral emissions measured using a high-resolution multi-track spectrometer, having a spectral resolution of 0.023 nm at a 50 μm entrance slit width. The neutral temperature estimation from the Doppler broadened spectral line was carried out after considering the Zeeman effect due to the magnetic field present in the tokamak. To accurately obtain the temperature of the neutral hydrogen, two temperature components (warm and hot) were required to be considered. A code was developed to obtain the neutral temperature and is used to analyze two typical plasma discharges. The temperature of warm components varies between 3 and 5 eV, while hot atoms have temperatures in the range of 15–30 eV. It was observed that the chord-integrated neutral temperature increases slightly towards the plasma core region compared to the plasma edge of Aditya-U tokamak
Modeling of the Hα Emission from ADITYA Tokamak Plasmas
No full textThe spatial profile of Hα spectrum is regularly measured using a high-resolution multi-track spectrometer in ADITYA tokamak to study the neutral particle behavior. The Monte Carlo neutral particle transport code DEGAS2 is used to model the experimental Hα spectral emissions. Through the modeling of the spectral line profile of Hα, it is found that the neutral hydrogen, which is produced from molecular hydrogen and molecular hydrogen ion dissociation processes contributes 56% to the total Hα emission, and the atoms which are produced from charge-exchange process have 30% contribution. Furthermore, the experimentally measured spatial profile of chord integrated brightness was modeled for the two plasma discharges having relatively high and low density to understand the neutral particle penetration. The presence of neutrals inside the core region of the ADITYA tokamak is mainly due to the charge-exchange process. Furthermore, it is observed that neutral particle penetration is lower in higher density discharge
Analysis of disruptive instabilities in Aditya tokamak discharges
No full text826-833Major disruptions
and sawteeth oscillations (internal disruptions) are routinely observed in
ohmically heated Aditya tokamak discharges and their characteristics have been
investigated with the help of soft X-ray (SXR) tomography along with other
diagnostics. The SXR tomography is carried out with the help of single array of
detectors assuming rigid rotation of the modes to analyse the mode structure of
sawtooth internal disruptions. Coupling of m/n=2/1
and m/n=1/1 modes could be the main
mechanism for the major disruption. Sawteeth periods were measured and compared
with the scaling laws and found to be in good agreement
Poloidal Rotation and Edge Ion Temperature Measurements Using Spectroscopy Diagnostic on Aditya-U Tokamak
No full textThe impurity ion poloidal rotation and ion temperature from the Aditya-U tokamak plasma have been measured using a high-resolution spectroscopic diagnostic. It comprises of a high resolution, 1 m, f/8.7, Czerny-Turner configuration spectrometer along with charge coupled device (CCD) detector. The system monitors the spectral line emission of C2+ impurity ions at 464.74 nm from the top port of the Aditya-U vacuum vessel with the lines of sight covering the plasma minor radius from r = 11.55 cm to 21.55 cm. The impurity ion poloidal rotation velocity and temperature have been estimated using the Doppler shift and Doppler broadening of the spectral lines respectively. The maximum poloidal rotation at a radial location of 21.55 cm in the edge of the plasma during the plasma current flat top was observed to be ~4 km/s for the analyzed discharges and the ion temperatures measured in the edge were in the range of 32–40 eV
Team perfectionism and team performance: A prospective study
No full textPerfectionism is a personality characteristic that has been found to predict sports performance in athletes. To date, however, research has exclusively examined this relationship at an individual level (i.e., athletes’ perfectionism predicting their personal performance). The current study extends this research to team sports by examining whether, when manifested at team level, perfectionism predicts team performance. A sample of 231 competitive rowers from 36 boats completed measures of self-oriented, team-oriented, and team-prescribed perfectionism prior to competing against one another in a 4-day rowing competition. Strong within-boat similarities in the levels of team members’ team-oriented perfectionism supported the existence of collective team-oriented perfectionism at the boat level. Two-level latent growth curve modeling of day-by-day boat performance showed that team-oriented perfectionism positively predicted the position of the boat in mid-competition and the linear improvement in position. The findings suggest that imposing perfectionistic standards on team members may drive teams to greater levels of performance
Report of an independent peer review of A forest management strategy for the proposed Coquille Forest submitted to the Coquille Indian Tribe by the Independent Scientific Advisory Team (ISAT)
No full text"[T]he [Coquille Indian] Tribe requested that the State of Oregon assemble a team of independent scientists to peer review the forest management strategy proposed by the ISAT. The purpose of the independent peer review would be to: 1) assess the degree to which the two major goals assigned by the Tribe are met by the proposed ISAT forest management strategy, 2) validate the scientific soundness of the proposed strategy, 3) identify any gaps in the strategy or components not adequately addressed, and 4) make recommendations to correct deficiencies or to make improvements in the strategy. In response to the Tribe's request, the Governor's Office of Natural Resources assembled a team of independent peer reviewers and structured the process by which the review would be accomplished. The results of the IPR were presented to the ISAT in a conference open to the public which was held on November 21, 1995 at the LaSells Stewart Center, Oregon State University. Following is a consolidated report of major conclusions and recommendations presented by the independent reviewers to the ISAT at the November 21 public forum.

Unreconcilable contradictions: the poetry of Aditya Prakash
No full textIs it possible that Anglophone Euro-American scholarship surrounding the Indian city, Chandigarh, focuses too heavily on certain figures associated with its design -such as Swiss-French architect and paragon of architectural modernism- Le Corbusier? With this question in mind, the following article focuses on the Indian architect Aditya Prakash- who worked alongside Le Corbusier during the design of Chandigarh-and the two poetry volumes he produced with Indian writer Mulk Raj Anand. This article contributes to an emerging body of research that suggests the need to de-emphasise Le Corbusier and to better understand the role of the Indian team in the design of Chandigarh. Through the analysis of hitherto under-researched poetry devoted to Chandigarh, this article offers a more nuanced understanding of Chandigarh, Aditya Prakash, and his relation to Le Corbusier
Evaluation of an Oxygen Transport Coefficient in the Aditya Tokamak Using the Radial Profile of O4+ Emissivity and the Importance of Atomic Data Used Therein
No full textOxygen impurity transport in the typical discharges of the Aditya tokamak was investigated using emissivity radial profile of emissivity of the spectral line (2p3p 3D3–2p3d 3F4) at 650.024 nm from the Be-like oxygen ion. This O4+ spectral line was recorded using a 1.0 m multi-track spectrometer capable of simultaneous measurements from eight lines of sight passing through the plasma. The oxygen transport coefficients were determined by reproducing the experimentally measured emissivity profiles of O4+, using a one-dimensional impurity transport code, STRAHL, and photon emissivity coefficient (PEC) belonging to that transition. The PEC values were obtained from both ADAS and NIFS atomic databases. Using both the databases, much higher values of diffusion coefficients compared to the neo-classical values were observed in both high and low magnetic field edge regions of typical Aditya tokamak Ohmic plasma. Although, almost similar profiles of diffusion coefficients were obtained using PEC values from both databases, the magnitude differs considerably. The maximum values of diffusion coefficients in the plasma edge at low field side of tokamak were ~45 and ~25 m2·s−1 when modeling was done using the ADAS and NIFS databases, respectively. Further analysis on the atomic data used in the calculation indicates that the difference in diffusion coefficients is mainly related to the variation in the values of atomic data of the two databases
