How can I remember the Formula for the impulse
A Geiger-Mueller tube is a radiation detector that consists of a closed, hollow, metal cylinder (the cathode) of inner radius ra and a coaxial cylindrical wire (the anode) of radius г (see figure below) with a gas filling the
space between the electrodes. Assume that the internal diameter of a Geiger-Mueller tube is 3.00 cm and that the wire along the axis has a diameter of 0.190 mm. The dielectric strength of the gas between the central wire
and the cylinder is 1.15 × 106 V/m. Use the equation 2πrlE =
9in
to calculate the maximum potential difference that can be applied between the wire and the cylinder before breakdown occurs in the gas.
