An electron is accelerated within a particle accelerator using a 100 MV electric potential. The 100 MeV electron moves along an evacuated tube of length 4 m, fixed to the laboratory frame.

What length of the tube would be measured by an observer moving with the electron?

Answer #1


Hence the length of the tube will 3.92 m in the electron's frame of reference.(or any inertial frame having 0 relative speed with the electron;in this case it is the frame of observer. )

PHW 21 due at Class 24 A particle accelerator is a device designed to create high-energy particles for collision experiments. In one such accelerator, protons that are initially at rest are accelerated through a net electrical potential ? to a total relativistic energy ? = 6.5 GeV. The accelerator itself is a large circular ring with a radius ? = 1.1 km. For these protons, calculate the following: (a) The net accelerating potential, ?. (b) Their momentum, in MeV/c. (c)...

At the 3-km-long Stanford Linear Accelerator, electrons are accelerated to final kinetic energies of 47 GeV. a. Electrons increase their kinetic energies approximately uniformly every meter as observed in the laboratory frame. What is the energy gain in MeV/m? b. Suppose the classical KE expression was correct – how far along the accelerator tube would the electrons need to travel before they reached light speed? c. OK, but that isn’t really what happens – even at 47 GeV of kinetic...

The Large Electron-Positron Collider (LEP) was an accelerator at CERN, the International particle physics laboratory in Europe. As its name implies, at LEP electrons (e- with mass of 0.51 MeV/c2) were collided close to head-on with their anti-particle, positrons (e+ with the same mass). Each of these particles was accelerated to an energy of 104.5 GeV by the time they collided. What is the Lorentz factor $\gamma$ of an electron at this energy? How fast as a fraction of the...

2 Equipartition The laws of statistical mechanics lead to a surprising, simple, and useful result — the Equipartition Theorem. In thermal equilibrium, the average energy of every degree of freedom is the same: hEi = 1 /2 kBT. A degree of freedom is a way in which the system can move or store energy. (In this expression and what follows, h· · ·i means the average of the quantity in brackets.) One consequence of this is the physicists’ form of...
