• Figuring out top heater length. If we use the 70 mm stroke, the heater length including its flange is 14 inches. This will allow the heater to lower 0.5 inches below the chamber center line, and with the 70 m stroke, the heater will clear the manipulator for the puck.

• The electrodes (ball and shed) were vacuum degas in Big Blue. Then the assembly was dry fitted. The puck retainer is made of three pieces, starting from the front plate: ceramic (which registers the puck), puck retainer which has the three sapphire rollers that also push the puck against the ceramic ring, and a spacer between the retainer and the ceramic ring. The spacer rotates freely, making the engagement of the puck with the retracting tool difficult. This is solved by locking the retainer to the spacer via a pin, which is being done at the machine shop.

• We also checked where is the triple point with the shed. The triple point will be now shifted to the actual braze by adding a 1/6" spacer betweeh the tip of the ceramic and the shed.
