| 1. An apparatus for diamond production in a deposition chamber, comprising:
a heat-sinking holder for holding a diamond and for making thermal contact with a side surface of the diamond adjacent to
an edge of a growth surface of the diamond, wherein a top edge of the heat-sinking holder is at a distance of 0-1.5 millimeters
below a top surface of the diamond:
a noncontact temperature measurement device positioned to measure temperature of the diamond across the top surface of the
diamond; and
a main process controller for receiving a temperature measurement from the noncontact temperature measurement device.
