1 Q7. The first ionization coefficient for a gas is approximately given by a = 30pe-150p/E , where p is pressure in mm.Hg and E is electric field in V/cm. Suppose that this gas is used for an experiment in a medium having electric field of E=12 kV/cm. a) Fill the following table for different values of gap distance (d), under standard atmospheric conditions in which pressure is 760 mm.Hg and the temperature is 20°C. d (cm) 1 3 5 Electron Multiplcation ४ Ub (kV) (p.d)critical (Torr.Cm b) We change the standard atmospheric conditions to a new condition in which pressure is 700 mm.Hg and the temperature is 45 °C, fill the aforementioned table for the new conditions.
