The MESA chambers were essentially the same as those in Salem NH.
They were not junk as some have surmised.....but ....GT had not successfully ever grown 265 Kg boules reliably or consistently.
They may have grown a "proof of concept" as mentioned several times early on but it was not a "good" boule. THey could grow 85, 100 and 115 Kg bouls and had announced 165bKG to be available 3rd qtr 2014.

Given another 12 months or so they might have been able to refine the process. They were playing with crucible size and thickness as well as heat extraction rates and a multitude of equipment variables just from manufacturing variables. The variables do not scale linearly and it took 3 weeks to get the results of a change. They were doing trial and error testing on a production scale......75 or more machines!!!That does not build good yield numbers.

I can not believe that the Engineering / Process people bought into the schedule. That was force fed on them by TG in my opinion
