Pedestals

Tres bruyants.. ?

Coupure a 520 minimale !!!

L'humidite remonte doucement (43 % / 38 % au bout d'1/2 h)

J'avais oublie de recharge la version FE1_24CH_2

Piedestaux ok run 738816 ( coupure a 485 devrait etre ok )

En fait tre peu de bruit a Vth > 480

Cosmics

Fig. 1: Efficiency of one gap with TFE/CO2/SF6 in blue, in orange is the calculated efficiency with 2 gaps

La precision sur HV eff depend de la pression , la temperature est restee stable a 18 C

P0(170 m) = 1007 +- 5 mBar

⇒ P a varie de 983 mBar a 993 mBar

⇒ On obtient un facteur $\alpha$ entre 0.2 pour mille et 8 pour mille, donc une variation maximale de 60 V entre les differents points
