The flight Dewar fully assembled, on a vibration table. Behind the Dewar on the right, you can see the vibration driver. This is essentially a gigantic speaker coil (Spinal Tap would love it!) attached to the table on which the Dewar is mounted. It is used to simulate the vibration that occurs during launch (19 g's of random vibration!)
