Sorry, I sent the wrong file.

Here is the temperature converter I provided to the shop folks.

Joe Winston advised me over the phone of how to operate the vacuum system during bakeout.

First change that cropped up is that we are moving the "monitor" thermocouples on similar port types (one port 12, one port 4, one of the 8" port extensions, etc.) from the center of the flange covers to the edge of the flange itself. We had actually planned to do that but it got missed somehow. We are seeing an expected long lag for the heat to migrate to the covers. We really need to monitor the temperature differential across the flange welds.

We are going to 170F on the shell and holding 120 on the ports while we move the thermocouples as stated above.

Here is the MTM plan.

We agreed to stick with the original plan for the first VVSA and then maybe see what adjustments can be made for the second and third. We turned on the heaters at 2:15 and they appeared to come up nicely. Initial pressure was 8 10-7. First setpoint was 120F - the pressure came up to 4 10-6. Next ramp up will be to 170 at 3:15.

We will ramp up per the attached plan. I have also attached the handy dandy temperature conversion chart I did for convenience. If there are any concerns or immediate reasons to stop please call me immediately at Major Tool 317 636 6433.

One question was what if the pressure comes up to 10-3 - what should they do with the vacuum system?

Thanks,
Mike
