RADIATION SENSITIVE DEVICES |
摘要 |
A radiation sensitive plate is provided with a discontinuous covering layer to improve vacuum drawdown. The covering layer is produced by dissolving the material which is to form the covering layer in a solvent so as to form a solution having a conductivity of from 10<3> to 10<9> pSm<-><1>. The solution is then directed towards the plate whilst providing a potential of at least 5 kV between the solution and the plate. The potential is the sole disruptive force in the liquid and draws the liquid into ligaments and disrupts the ligaments to form drops of substantially equal size which are then deposited on the plate. |
