The anode plug ( Figure 2 ) was inserted into a carbon anode holder .
To reduce heat transfer from the hot gas to this anode holder outside the region of the arc , a carbon shield was attached to the surface providing an air gap of 1/16 inch between the plate and the surface of the anode holder .
In_addition , the inner surface of the carbon shield was covered with aluminum_foil to reduce radiation .
Simultaneously with the anode surface temperature and voltage measurements pyrometer readings were taken along the cylindrical surface of the carbon anode holder as indicated on figure 2 .

It would appear that it should be possible to determine unique mechanisms for the thermal and photochemical_reactions in both the liquid and gas phases and to determine values for activation_energies of some of the intermediate reactions of atoms and free_radicals , as_well_as information on the heat_of_dissociation of the carbon halogen bond .
