Attempt to Correlate the Ionic Model with Observations in BaBar RPC Chambers and R& D Tests
- SLAC
The paper presents a model of ionic conduction in the Bakelite-based RPC detectors. This model explains why these detectors need to add water while they operate. The electrode current, according to the presented model, is formed mainly by the ionic sequence involving the phenol impurities left in the Bakelite and water, both left from the initial production. Similar ionic process is present in the Linseed oil polymer, where the current is carried by the fatty acid molecular impurities and by water. The Bakelite RPC operation requires the entire ionic sequence to operate smoothly to keep the electrode resistance constant.
