Original post date (Japanese version): June 22, 2024

Step-up: 160kV (Standby) -> 200kV (Operation)

1. Confirm that the accelerating voltage is in the standby state (160kV) and the dark current (Beam Current when the electron beam is stopped) is 80±2uA.
   1. [TEM Center: Upper menu] Control → Beam
      • Display Beam Controller (for JEM Administrators)
   2. Check HT Voltage / Current HT: (160kV)
      • If stopped, contact the administrator (Do not step up)
   3. Check Filament / Beam Current HT: (80±2uA)
      • If not stable, contact the administrator (Do not step up)
2. Step up slowly to avoid discharge
   1. [TEM Center: Upper menu] Application → HT Scheduling
      • Display HT Scheduling
   2. Set the step-up conditions in Liner Step
      • Step Volt = 0.1kV, Interval Time = 3s

Step-down: 200kV (Operation) -> 160kV (Standby)

1. Set the accelerating voltage to 160kV (standby state)
   1. [TEM Center: Upper menu] Control → Beam
      • Display Beam Controller (for JEM Administrators)
   2. HT Voltage: Select [160]
   3. Check Filament / Beam Current HT: (80±2uA)
      • If not stable, contact the administrator
