Figure 8
Isotherms (constant temperature contours in K) inside the biocrystal for four different sizes of X-ray beam with constant flux, showing the internal temperature distribution dependence on the size of the source beam (i.e. on the flux density). Smaller more focused X-ray beams result in sharper internal temperature gradients (energy is deposited in a smaller region) and slightly higher maximum temperatures, although the average bulk temperature of the sphere remains fairly constant: (a) side view (YZ plane) and (b) front view (XY plane). |
