Abstract :
The OPERA RPC HV system has been implemented using custom current measurement/distribution systems developed by the LNF Electronics Workshop.
ystem features eight inputs and 24 outputs (1–3 modularity). The current on each channel is measured with 100 pA sensitivity and 3 % accuracy in the 1 nA– 25 μ A range.
paper we describe the measurement circuit as well as the results of the tests we have carried out to qualify the system.
