Abstract
We have studied the long-term operation of gas microstrip detectors wh ich have been passivated with a layer of nickel oxide. We have used as the active gas CF4/isobutane (80:20) and three different types of sub strates: Tedlar, glass and Upilex. In all three cases we found that th e detectors are stable after passivation and can operate for a month w ithout changes in gain at rates of MHz. The total accumulated charge w as approximately 100 mC.
