摘要：
Results from high energy nucleus-nucleus collisions at RHIC have shown the importance of particle identification in a very large momentum range, in particular for protons. The ALICE experiment has unique capabilities to identify particles; however its momentum coverage for track-by-track identification should be extended to meet new physics challenges at LHC. The Very High Momentum Charged Particle Identification (VHMPID) detector represents a possible upgrade of the ALICE experimental apparatus. It has been conceived to extend proton identification on a track-by-track basis up to p = 30 GeV/c. The VHMPID is a Ring Imaging Cherenkov with C(4)F(10) gaseous radiator coupled to a CsI based photon detector. The focusing properties of a spherical mirror are exploited to focus Cherenkov photons on the photon detector. The detector layout and the expected performance will be discussed. First results from beam tests of a prototype of 60x40 cm(2) will be also presented. [GRAPHICS] .
