Bruno Touschek [SEP] date of birth
Bruno Touschek
Bruno Touschek (3 February 1921 – 25 May 1978) was an Austrian physicist, a survivor of the Holocaust, and initiator of research on electron-positron colliders.
Biography.
Touschek was born and attended school in Vienna. In 1937, he was not allowed to finish high school since his mother was Jewish. He passed the final year exam in a different school as an external pupil. Shortly after he started studying physics and mathematics at the University in Vienna, he again had to quit for
Touschek effect
The Touschek effect describes the scattering and loss of charged particles in a storage ring. It was discovered by Bruno Touschek.
It is determined by the average of the scattering rate around the ring
In fact, since the momentum acceptance for scattering with energy gain may be different from that for scattering with energy loss, the lifetime must be computed by taking into account the positive and negative momentum acceptances, i.e.
A formula for the local scattering rate, given by Bruck, is
