When a powerful laser is employed in the Earth's atmosphere, the accompanying electric field may ionize the air, transforming it into a plasma that reflects the laser light. Electric breakdown occurs in dry air at 0°C and 1 atm when field amplitudes above around 3:00 Mv/m a). At this maximum intensity, how much Power can a cylindrical beam with a diameter of 4.03 mm deliver? Note Answer must be in W.

A limitation on how many spectra per second can be recorded by a time-of-flight mass spectrometer is the time it takes the slowest ion to go from the source to the detector. Suppose we want to scan up to m/z 500 for ions with z = 1. Calculate the speed of this heaviest ion if it is accelerated through 5.00 kV in the source. How long would it take to drift 2.00 m through a spectrometer? At what frequency could you record spectra if a new extraction cycle were begun each time the heaviest ion reached the detector? What would be the frequency if you wanted to scan up to m/z 1000?
