Below is a list of ghost beam measurements from its discovery in August 2018 to present.

August 2018

  • 8/16/18 Mamun ended a 1mA electron beam that ran for 9 hours. Gun HV: 200kV, Gun Solenoid at 200A, Anode bias at 1kV. [1]
  • 8/16/18 After discontinuing the laser, the ghost beam was visible on all three viewers and had a very high intensity. Mamun lowered the gun solenoid current to zero and then returned it to its original current but the ghost beam disappeared [2].
  • 8/17/18 A brief rise in vacuum pressure near the gun was observed [3]
