1. Plans for the LHC BGI simulations
Impedance meeting,
Marcin Patecki, Mariusz Sapiński

2. BGI operation principle
High Voltage: -2kV applied for cathode and +2kV for anode
Magnetic field of 0.22 T
Filled with Neon gas of density < 10 −8 𝑔/𝑐 𝑚 3

4. High voltage instabilities
We observe the high voltage instabilities
We suspect the wakefields as the reason
