Neutron SC (inv20)

1

• Neutron SC (inv20) 1e14 neq Si
• 1000 V (without scan)
• signal goes down in time antipumping
• (the same stationary signal one gets in scan
  mode)
• CCE 50-60 in stationary state
• (normalized initial value)!!!!!!!

• Pion pCVD (L107-2) 1e15
• 1000 V (without scan)
• signal goes up in time pumping
• (the same stationary signal one gets in scan
  mode)
• CCE 70 (normalized to expected initial value)!

Electron signal after 2h of negative bias with
Am241 on (hole injection priming)
electrons
electrons
Polarization is large (signal at 0V)! signal
vanishes (field moves away after 1h)
