Halo and Tail Generation

Halo and Tail Generation HTGEN

study of potential sources of halo and tail generation in Linear colliders
with development of analytical models of halo, estimates of halo population,
development of computer models for halo/ tail generation,
simulation studies of halo/tail generation and benchmarking

HTGEN was launched as task within EuroTeV WP6 on Integrated Luminosity Performance Studies activity.
Contact person is Helmut Burkhardt (CERN).
