Abstract
A detector assembly includes a hollow body in which a printed circuit board, a resistive plate, a drilled board, a drift volume, and a cathode are disposed. A surface of the printed circuit board exposed to the resistive plate includes printed circuit lines for measuring first and second coordinates of a charge event. The hollow body can include a sealable opening to remove contaminants outgassed from one or more components of the detector assembly and to fill the hollow body with an operational gas. The sealable opening can be fluidly coupled to a gas and vacuum system to reduce the concentration of the outgassed contaminants.
