- Wakefield
- The field created by a bunch of charged particles as it
passes through a beam pipe. The charges induced in the wall of a
beam pipe by the leading edge of the bunch have an effect
(usually bad) on the tail of the bunch. If the beam is centered,
wakefields will cancel each other by symmetry, but if the beam is
closer to one wall, the tail will be attracted to this wall
resulting in a `banana' shaped bunch (Transverse Wakefield). A
wakefield also can be created in RF cavities by the loading
effect: the tail gets less energy than the head of the bunch
(Longitudinal Wakefield). The deceleration on parts of the bunch
caused by wakefields can be up to 2 GeV.

- Web Server
- A computer that delivers (serves up) Web pages. Every Web
server has an IP address and possibly a domain name. For example,
if you enter the URL http://www.slac.stanford.edu/detailed.html
in your browser, this sends a request to the server whose domain
name is slac.stanford.edu. The server then fetches the page named
detailed.html and sends it to your browser.

- Wire Scanner
- Wire scanners are beam profile monitors used to provide
accurate measurements of beam size and position in all three
planes (vertical, horizontal and longitudinal) for beam feedback
systems and beam optimization procedures. Components include
wires capable of being moved precisely through the path of a
beam, and a detector which can accurately measure the amount of
charge striking a wire. When in use, a wire is scanned across the
path of a beam, and a plot of wire position versus beam intensity
is generated that represents the beam profile. Wire scanners are
used to measure the emittance of the beam.
