A cyclotron is used to produce a beam of high-energy deuterons that then collide with a target to produce radioactive isotopes for a medical procedure. Deuterons are nuclei of deuterium, an isotope of hydrogen, consisting of one neutron and one proton, with total mass 3.34 x 10-27 kg. The deuterons exit the cyclotron with a kinetic energy of 5.00 MeV.a. What is the speed of the deuterons when they exit?b. If the magnetic field inside the cyclotron is 1.25 T, what is the diameter of the deuterons’ largest orbit, just before they exit?c. If the beam current is 400 μA, how many deuterons strike the target each second?
On December 27, 2004, astronomers observed the brightest flash of light ever recorded from
outside of our solar system. It came from a highly magnetic neutron star SGR 1806-20 (also know
as a magnetar). During the 0.20 s burst, this star released as much energy as our sun would over
a period of 250,000 years. If our sun outputs approximately Psun = 3.846x 1026 W, what was the
average power output of this magnetar in terms of Psun?
No magnetic poles have ever been seen in nature, but we can assume
that they exist and generalize Maxwell's equations accordingly.
The generalized Maxwell equations in this case (in Gaussian units)
will be as follows:
V.Ē = 47Pe
V.B = 4TPm
1 0B 4 Jm
V xE =
с де
V ×B =
c ôt
-Je
In the above expressions, pm is the magnetic charge density and jm is
the magnetic current density. For simplicity, we denote the set of
electrical and magnetic quantities by e and M. in other words
M = (B, Jm; Pm, ...) , E = (E, Je, Pe, ...)
