flu·ence (H),

(flū'ens),
A measure of the quantity of x-radiation in a beam in diagnostic radiology, either particle fluence, the number of photons passing an aperture of unit cross-sectional area, or energy fluence, the sum of the energies of the photons passing through a unit area. Compare: flux.

flu·ence

(flū'ĕns)
A measure of the quantity of x-radiation in a beam in diagnostic radiology, either particle fluence, the number of photons entering a sphere of unit cross-sectional area, or energy fluence, the sum of the energies of the photons passing through a unit area.

fluence

(floo′ĕns) [L. fluere, to flow]
In radiation oncology, the number of photons per unit area, measured in J/m2 (joules/square meter). Fluence is one of several modifiable factors in the treatment of diseased tissues with radiation.

Above all, the micro-adjustments in spot size at high fluence levels will allow users to achieve faster and more efficient treatments.
The decrease in the average surface roughness is also observed in 20 [micro]m PVDF samples irradiated with 75 MeV Oxygen-ion beam at different fluences and this decrease in the average surface roughness is depend on the fluence.
It has been shown that the average surface roughness and grain size decreases upon SHI irradiation and the decrease in surface roughness are dependent on the type of swift heavy ion beam and its energy and fluences.
More fluence would give a larger distance between hils.
The surface roughness depends on laser treatment parameters: wavelength, pulse duration, fluence and number of pulses.
The laser energies in terms of applied fluence and number of pulses varied in different experiments so as to study their effects upon samples.
The LAPG non-sequential scanner is more comfortable, more uniform, less tedious, and achieves higher fluences and shorter pulse widths than large- field hair removal devices.
These include the flexibility to select the wavelength - 585, 590, 595, or 600 nm - and the fluence that is most appropriate for each patient for effective treatment of veins and lesions of different sizes, shapes, locations, and depths.
It does so by delivering a combination of high fluences (50 J/cm2) and extremely long pulses (up to 20 msec) to damage large targets in the dermis--like hair and leg veins--while leaving the smaller surrounding structures unharmed.
These higher fluences offer an even more effective treatment with no long-term adverse effects.
The fraction of unablated surface obviously depends on initial fluence or energy density's impingement on the surface of SMC.
