The 3.20 - km - longSLAC produces a beam of 50 GeV electrons. If there are 15,000 accelerating tubes, what average voltage must be across the gaps between them to achieve this energy?

Short Answer

Expert verified

The voltage across the gap between the tubes is 3.33MV.

Step by step solution

01

Definition of voltage 

Voltage is the pressure from the power source of an electrical circuit that allows charged electrons (currents) to pass through conductive loops and allow them to do their jobs. B. Make the light shine.

02

Given Data

Length of the accelerator, l = 3.20 km

Number of accelerating tubes,\(n = 15000\)

Energy of the beam,\(E = 50.0\;{\rm{GeV}}\)

03

Finding Average voltage 

The general voltage among the 15,000 tubes can be obtained using the following formula \({\rm{P}} \cdot {\rm{E = e}}{{\rm{V}}_{\rm{t}}}\), where P. E is the energy of the beam of the electrons and Vt is the total voltage.

By dividing the total voltage of the 15,000 tubes, you can get the voltage of the gap between them:

\(\begin{array}{c}{{\rm{V}}_{\rm{t}}}{\rm{ = }}\frac{{{\rm{P}}{\rm{.E}}}}{{\rm{e}}}\\{\rm{ = }}\frac{{{\rm{50}}\;{\rm{GeV}}}}{{\rm{e}}}\\{\rm{ = 50}}\;{\rm{GV}}\end{array}\)

\(\begin{array}{c}{\rm{V = }}\frac{{{\rm{50}}\;{\rm{GV}}}}{{{\rm{15,000}}}}\\{\rm{ = 3}}{\rm{.33 \times 1}}{{\rm{0}}^{\rm{6}}}{\rm{\;V}}\end{array}\)

Hence, the voltage across the gap between the tubes 3.33MV.

Plans for an accelerator that produces a secondary beam of \({\rm{K}}\)-mesons to scatter from nuclei, for the purpose of studying the strong force, call for them to have a kinetic energy of \({\rm{500 MeV}}\).

(a) What would the relativistic quantity \(\gamma {\rm{ = }}\frac{{\rm{1}}}{{\sqrt {{\rm{1 - }}{{{{\rm{\nu }}^{\rm{2}}}} \mathord{\left/{\vphantom {{{{\rm{\nu }}^{\rm{2}}}} {{{\rm{c}}^{\rm{2}}}}}} \right. \\} {{{\rm{c}}^{\rm{2}}}}}} }}\) be for these particles?

(b) How long would their average lifetime be in the laboratory?

(c) How far could they travel in this time?

The principal decay mode of the sigma zero is \[{{\rm{\Sigma }}^{\rm{0}}}{\rm{ }} \to {\rm{ }}{{\rm{\Lambda }}^{\rm{0}}}{\rm{ + \gamma }}\]. (a) What energy is released? (b) Considering the quark structure of the two baryons, does it appear that the \[{{\rm{\Sigma }}^{\rm{0}}}\]is an excited state of the \[{{\rm{\Lambda }}^{\rm{0}}}\]? (c) Verify that strangeness, charge, and baryon number are conserved in the decay. (d) Considering the preceding and the short lifetime, can the weak force be responsible? State why or why not.

Is the decay \({\rm{n}} \to {{\rm{e}}^{\rm{ + }}}{\rm{ + }}{{\rm{e}}^{\rm{ - }}}\)possible considering the appropriate conservation laws? State why or why not.

The total energy in the beam of an accelerator is far greater than the energy of the individual beam particles. Why isn't this total energy available to create a single extremely massive particle?

The quark flavor changed \[ \to {\rm{u}}\] takes place in \[{\rm{\beta - }}\]decay. Does this mean that the reverse quark flavor changed \[{\rm{u}} \to \] takes place in \[{\rm{\beta + }}\] decay? Justify your response by writing the decay in terms of the quark constituents, noting that it looks as if a proton is converted into a neutron in \[{\rm{\beta + }}\]decay.
