    Notes: Stark-shift measurements using emission spectroscopy are a powerful tool for advancing understanding in many plasma physics experiments. We use simultaneous two-dimensional space- and time-resolved spectra to study the electric field evolution in the 20 TW Particle Beam Fusion Accelerator II ion diode acceleration gap. Fiber optic arrays transport light from the gap to remote streaked spectrographs operated in a multiplexed mode that enables recording time-resolved spectra from eight spatial locations on a single instrument. Design optimization and characterization measurements of the multiplexed spectrograph properties include the astigmatism, resolution, dispersion, and sensitivity. A semiautomated line-fitting procedure determines the Stark shift and the related uncertainties. Fields up to 10 MV/cm are measured with an accuracy ±2%–4%. Detailed tests of the procedure confirm that the uncertainty in the wavelength-shift error bars is less than ±20%. Development of an active spectroscopy probe technique that uses laser-induced fluorescence from an injected atomic beam to obtain three-dimensional space- and time-resolved measurements of the electric and magnetic fields is in progress. © 1997 American Institute of Physics.

    Absorption spectroscopy characterization measurements of a laser-produced Na atomic beam : Proceedings of the eleventh topical conference on high temperature plasma diagnostics (1997)

    Notes: A pulsed Na atomic beam source developed for spectroscopic diagnosis of a high-power ion diode is described. The goal is to produce a ∼1012-cm−3-density Na atomic beam that can be injected into the diode acceleration gap to measure electric and magnetic fields from the Stark and Zeeman effects through laser-induced fluorescence or absorption spectroscopy. A ∼10 ns full width at half-maximum (FWHM), 1.06 μm, 0.6 J/cm2 laser incident through a glass slide heats a Na-bearing thin film, creating a plasma that generates a sodium vapor plume. A ∼1 μs FWHM dye laser beam tuned to 5890 Å is used for absorption measurement of the Na I resonant doublet by viewing parallel to the film surface. The dye laser light is coupled through a fiber to a spectrograph with a time-integrated charge-coupled-device camera. A two-dimensional mapping of the Na vapor density is obtained through absorption measurements at different spatial locations. Time-of-flight and Doppler broadening of the absorption with ∼0.1 Å spectral resolution indicate that the Na neutral vapor temperature is about 0.5–2 eV. Laser-induced fluorescence from ∼1×1012 cm−3 Na I 3s-3p lines observed with a streaked spectrograph provides a signal level sufficient for ∼±0.06 Å wavelength shift measurements in a mock-up of an ion diode experiment. © 1997 American Institute of Physics.

    The feasibility of abrupt methadone-buprenorphine transfer in British opiate addicts in an outpatient setting (1997)

    Notes: Abstract A study of 13 male opiate addicts was undertaken to investigate the feasibility of transferring abruptly from methadone maintenance treatment to buprenorphine in an outpatient setting. The mean age of subjects was 30 years (range 18-45) and all fulfilled DSM-III-R criteria for opioid dependence. All were maintained on a methadone dose of 20-30 mg mixture daily and were transferred for 3 days to 4 mg buprenorphine sublingually 24-26 hours after their last dose of methadone. On day 1 repeated measures of drug effects were performed, including agonist and withdrawal effects, and this was complemented by saccadic eye movements, a potential new measure of central opioid effects. These recordings were repeated once on days 2 and 3 and the subjects returned to their previous dose of methadone on day 4. Buprenorphine caused no detectable agonist effects or drug “high”, but had “good” effects, was “liked” and well tolerated, suggesting that subjects would comply with buprenorphine treatment despite the lack of reinforcing effects. A mild increase in subjective withdrawal symptoms, which was not clinically significant, was seen in association with an increase in saccadic peak velocity on day 2 of the study but no withdrawal occurred on the other days, indicating that the abrupt transfer technique was acceptable.

    Notes: Abstract The stereotypical professional male dancer is a gay man. However, little if any systematic research has investigated the validity of this stereotype, much less the reasons why male sexual orientation would be associated with interest in dance. We interviewed 136 professional dancers about the prevalence of homosexuality among dancers, the dancers' own sexual development, and relationships between dancers of different sexual orientations. Dancers estimated that over half of male dancers are gay, but that only a small minority of female dancers are lesbian. Gay men recalled more intense early interest in dance compared to heterosexual men and women, and were more feminine as boys than were heterosexual men. Gay men's homosexual feelings typically preceded their dance experience, and only one gay man felt that his dance experiences may have influenced his sexual orientation. Heterosexual men voiced some mild complaints about gay male dancers, but these were balanced by positive sentiments.
