- Waiting for the chemicals for the wire deadening; probably will start testing the procedure beginning of next week. Bill: what is the wire diameter needed to deaden the wire? Lubomir: according to Garfield if we make sense wires 40um signal drops by factor of 40, for 60um - factor of 400, and for 80um -factor of 2,700. After some discussions, Bill will look what is the sagging effect of thickening the wires and Lubomir will estimate the suppression factor that we need. | - Waiting for the chemicals for the wire deadening; probably will start testing the procedure beginning of next week.
