A proton beam is used to irradiate a tumor. The beam is created starting with hydrogen gas, ripping off the electrons, and extracting the protons in an electric field. The protons are accelerated from approximately rest across a potential difference totaling 8.3 million Volts. The speed of the protons after acceleration is …

In proton-beam therapy, a high-energy beam of protons is fired at a tumor. The protons come to rest in the tumor, depositing their kinetic energy and breaking apart the tumor’s DNA, thus killing its cells. For one patient, it is desired that 0.10 JJ of proton energy be deposited in a tumor. To create the proton beam, the protons are accelerated from rest through a 23 MVMV potential difference. What is the total charge of the protons that must be...

In proton beam therapy, a beam of high-energy protons is used to kill cancerous cells in a tumor. In one system, the beam, which consists of protons with an energy of 2.8×10−11J, has a current of 72 nA. The protons in the beam mostly come to rest within the tumor. The radiologist has ordered a total dose corresponding to 3.8×10−3J of energy to be deposited in the tumor. Part A How many protons strike the tumor each second? Express your...

In one model of the hydrogen atom, an electron orbits a proton in a circle of radius 5.28×10-11 m with a speed of 2.18×106 m/s. What is the acceleration of the electron in this model? What is the period of the motion?

8) Press Add tumor and try to selectively target the hydrogen nuclei at the location of the tumor. You can achieve this by changing the frequency of the radio wave or by changing the strength of the main magnetic field. Note: in an actual MRI neither is done and the gradient magnetic field is changed. Explain why changing the strength of the gradient field allows the selective stimulation of the hydrogen nuclei in one slice.

A 5.0 mm diameter proton beam carries a total current of 1.5mA. The current density in the proton beam, which increases with distance from the center, is given by J = Jedge(r/R), where R is the radius of the beam and Jedge is the current density at the edge. I calculated that 9.375 x 10^15 protons are delivered by the proton beam each second, but I do not know where to start in calculating the value of Jedge. I am...

In a colliding beam storage ring an antiproton going east passes a proton going west, the distance of closest approach being . The kinetic energy of each particle in the lab frame is 93GeV , corresponding to γ=100 . In the rest frame of the proton, what is the maximum intensity of the electric field at the proton due to the charge on the antiproton? For about how long, approximately, does the field exceed half its maximum intensity?
