Amplifier PAD board +HV Hexcel Metal support Hexcel mat study after drying in microwave Setup of run 164-165, before installation the hexcel mat was dried in microwave oven during 30 minutes HEC strange signals
Signals (Run 164-165) HEC strange signals
Signal amplitude distribution (Run 164-165) HEC strange signals
Frequency (Run 164-165) No data HEC strange signals
Conclusion : • After drying of hexcel mat in microwave oven first pulse appeared in 10 minutes, second – in a hour. • A rise of frequency was observed during few hours. HEC strange signals
Run 166 • Run 166 has been taken after 4 days keeping in normal condition (hexcel mat should be already wet) • Signals appeared immediately after HV=on HEC strange signals
