BML-D 001 Monitoring Paolo Iengo Atlas RPC Group Napoli ( M. Alviggi, V. Canale, M. Caprio, G. Carlino, F. Conventi, R. de Asmundis, M.Della Pietra, D. della Volpe, P.I., S.Patricelli, L.Romano, G. Sekhniaidze )
Overview Plot & Fit V-I Historical Trends of Fit Parameter Monitoring of Current, HV, Temp. etc Conclusions
Plot V-I FIT: I(V) = a+bV V<4000 Volt I(V) = a+bV +k (exp(V/c) –1) V>5000 Volt
Plot V-I < 1 July> 1 July
Historical Trend of Linear Slope T = 20 exp(- (T-20)) = 1/12
Historical Trend of Exp. Slope
5 – 15 June Currents CAEN H.V. 60 µA 11 kV
24 June – 8 July Currents CAEN H.V.
Currents Temperatures Gas Flow 134 A SF6 Isob.
Currents Isob. Flow
CAEN H.V. Currents 9 – 16 July
Currents CAEN H.V. Temperatures
Conclusions Behavior of BML-D 001 quite stable Increasing current on one layer due to the problem on isobutane Delay between HV and regime current needs more investigation Continuous Monitoring of HV, Current, Gas Flow & Env. Parameters is Essential
