MICHAEL MANGA: Recent Refereed Publications
Manga, M. and R. Jeanloz (1996)
Vertical Temperature gradients in the laser-heated diamond cell,
Geophysical Research Letters, vol. 23, 1845-1848.
Temperature gradients inside the laser-heated diamond cell are
not measured in the axial direction, along the optic axis, yet can bias
estimates of the peak temperatures achieved in
optically thin (dielectric)
samples such as Mg-silicate perovskite. Thermal diffusion calculations
show that the observed thermal-radiation spectrum is
not significantly affected by axial temperature gradients.
The apparent (measured) temperature
underestimates the actual peak sample temperature
by 350-850 K for 4000 < T < 6000 K.
