This demonstration shows some events from the LEP Collider in which
an electron
and a positron annihilate to form the particles seen in the detector.
You can look at the events from
different viewing points and at different magnifications by using the controls
provided to rotate the events and to zoom in and out.
The Event Display runs within your browser as
a Java applet.
This means that you must use a browser that includes Java support.
There are two versions of the Event Display. The old one, ralwired97,
will work in older Java implemenations (JDK 1.0), while
the new version, ralwired98, requires the latest version of Java (JDK 1.1).
The Java applet itself is about 500kb.
Please be patient - the Event Display may take a little time to start up
for the first time after it is loaded.
On most browsers you can see how it is progressing by opening the
Java Console.
The various options above belie the Java hype, "write once,
run everywhere" - more like "write once, debug everywhere".
Still, Java's better in this respect than the alternatives
("write once, run once," or am I belabouring the slogan?).
DELPHI
event detective. The DELPHI detector
also provided data for the above Event Display. Some of the background information
used here was based on the DELPHI event detective.
100 Years of Electrons. Some
of the event explanations used here were based on these pages.
