The X-ray experiment in the 1st year laboratory involves a high voltage (up to 28 kV) source of electrons which hit a target made of copper. This causes the electrons to decelerate, which results in the emission of "Bremstrahlung" X-rays, as well as characteristic peaks. The maximum X-ray energy is 28 keV. The door of the X-ray set is made of leaded glass. This attenuates the X-rays, according to the following equation: lo exp (-ut) Here l is the transmitted...
a) What is the minimum potential difference between the filament and the target of an X-ray tube if the tube is to accelerate electrons to produce X-rays with a wavelength of 0.477 nm? b) What is the shortest wavelength produced in an X-ray tube operated at 28.0 kV?
Question 1: An observer uses an X-ray telescope with an effective area of 500 cm^2 to search for X-ray emission lines in the spectrum of an accreting neutron star. At the energy of the target line, 6.7 keV, the continuum (arising from accretion) contributes 1.2 × 10^−3 counts/s/cm2/keV. In a spectrum accumulated over a 1 ks observation, the observer measures a total of 162 counts from within a 0.2 keV range centred on the target line energy. What is the...

The tube in a medical research X-ray unit uses lead (Z=82) as it's target. 1) Use the Bohr model to estimate the minimum kinetic energy electrons must have to in order for Kα X-rays to just appear in the X-ray spectrum of the tube. Ee = 2) Assuming the electrons are accelerated from rest through a voltage, V, what is the minimum voltage necessary to produce the Kα X-rays?
