=====Radio Frequency Quadrupole(RFQ)=====

===Info===
A Radio Frequency Quadrupole, or RFQ, is an important device that is used to apply certain properties to beam. Essentially an RFQ is a long, electric quadrupole focusing channel, excited at RF frequencies. An RFQ provides three essential things for beams before acceleration begins. First the beam is focused due to the electric fields produced by the excitation of the quadrupole focusing channel, second the RFQ provides much needed beam bunching, third the RFQ accelerates the beam. The RFQ is the first major device at both FRIB and ReA that prepares beam to be accelerated by the RF cavities. The combination of focusing, bunching, and accelerating working with the GTS is extremely important to getting the timing of the RF cavities correct.

===Tips/Notes===


===Location===
There are two large RFQs, one in the FRIB MEBT section and one in the ReA Front End.
