The target UCx28 that was previously conditioned , was set again in the EVAP1 for re-conditioning,

the reason was to get rid of all the material that could evaporate from the target and has the potential of clogging the ionizer.

EVAP1 currently pumping down.

The heating conditions are the same as the previous conditioning:

TGHT= 1 A/min to 438 A (same current used to reach 1900C in evap2 when sintering TaC coating - elog-455 evap2)

TBHT= 1 A/min 230 A

IGP1 = 1.51e-6 Torr

The cooling conditions are the same as the previous conditioning:

TGHT= -1 A/min 

TBHT= -0.5 A/min

EVAP1 was vented with Ar, the target was removed from the heating chamber to exchange the Ta cap for a new one.

The old Ta cap was not fully coated and it presented a different coloration with respect to the 2 previous caps used for conditioning.
