1064 (M)
  • 1066: Three capacitor banks with surge resistor partially visible at left (see 1048).
    • There was a capacitor bank for each phase of the three phase power.
    • The capacitor bank stored 250,000 coulombs of energy to supply power during the klystron beam pulse.
  • 1065: Closer view of capacitor bank.
  • 1064: Capacitor banks with rectifier stack partially visible on left (see 1076).
    • Shock isolation equipment can be seen at right.
    • Surge resistor can be seen in the distance at the end of the room (see 1048).

  • 1110: Step-up transformer drawing with statistics.
  • 1048: Crowbar (left), surge resistor (right).
    • The crowbar's primary purpose was to protect the klystron from being destroyed by internal arcing or other malfunctions.
    • Using a vacuum spark gap, the crowbar fired in case of TWT arcing, interlock operation, or other faults requiring rapid removal of high voltage.

  • 1070, 1074: Platform can be seen above each klystron tank.
    • All components needed to pulse the modulating anode were immersed in the oil tank.
    • The water cooled collector portion of the klystron was housed under the shield on the platform above the tank. This shield was commonly referred to as the klystron "hat."
      • Each shield weighed approximately 6,000 pounds was constructed of 3/4 inch lead with a 1/4 inch stainles steel liner to provide X-ray protection.
    • 1074: The microwave balcony containing the high level wave guide switches (kludge) is in the upper left (above the fluorescent light).
