My name is Rob Mackintosh.  I\u2019m in the San Diego Men\u2019s Division.  I attended my first men\u2019s team meeting in late 2007.  Did the Legacy Discovery in 2008 and the Sterling Men’s Weekend in 2015.  <\/p>\n\n\n\n

What am I building?<\/strong><\/em><\/p>\n\n\n\n

My employer General Atomics is building two magnetic field chambers for Fermi National Labs for a scientific experiment called Mu2e.  I\u2019m the senior engineer for this project.  I\u2019m a mechanical engineer.  I graduated from New Mexico State back in 1989.  <\/p>\n\n\n\n

The magnetic field chambers require super conducting wire in order to generate the magnetic fields required for the experiment.  The chambers are somewhat similar to MRI machines but are much larger. I lifted the image below from Googling images of Mu2e:<\/p>\n\n\n\n

We are building the Production Solenoid and the Detector Solenoid.\u00a0\u00a0The magnetic fields are shown above in Tesla (4.6T = 4.6 Tesla).<\/p>\n\n\n\n

How are you doing it?<\/strong><\/em><\/p>\n\n\n\n

Shortly after a contract was awarded to General Atomics I was assigned to the project to design what we call the vacuum chambers (also called cryostats). The cryostats are shown in green above. The magnetic field windings (also called solenoids) are in the annulus and are colored white and pink. We created all the drawings in San Diego and are building the units in Tupelo Mississippi. These days I write technical manuals with instructions on how to build and assemble the units. We are getting close to finishing the first of the two: the Production Solenoid. <\/p>\n\n\n\n

I fly to Mississippi quite often to interface with the crew down there.  We also rely very heavily on MS Teams (similar to Zoom) to convey information back and forth.  I look at a lot of pictures.  I do a lot of modeling in CAD to generate illustrations for instructions on how to get stuff done.  The images below instruct on the insertion of thermal shields into the cryostat of the Production Solenoid.   <\/p>\n\n\n\n
