Description
Based on the results in the RHIC heavy ion experiments
the identification of very high pT particles
seems to be extremely interesting at LHC energies.
ALICE performes an excellent event by event PID below 5 GeV/c
even in those high track densities. However, the track-by-track
analysis of the heavy ion data demands further efforts on
the experimental side.
We are presenting the idea of an ALICE upgrade detector which
is capable to extend the particle identification into the
momentum region of 5-25 GeV/c on track-by-track basis.
The Very High Momentum Particle Identification Detector (VHMPID)
is a gaseous Cherenkov detector, capable to distinguish
charged pions, kaons and protons/antiprotons in the above
momentum window in event by event. This feature gives us the
possibility to study the meson/baryon anomaly,
multi jet fragmantation function, in medium effects
and the same-side and away-side jet correlations.
The talk is focused on design issues and technical
aspects of such a detector, with present simulation
and the prototype test results of the VHMPID.
