Description
Measurement of a particle detection time with accuracy better $30~ps$ could help to separate particles from different vertexes in future experiments at hadron colliders with high Luminosity (for instance at LHC Phase III L~10$^{35}cm^{–2}·s^{–1}$). From other hand measurement of Time-of-Flight with such accuracy could sufficiently improve power of particle identification technique in various colliding beam experiments. Now the MCP based charge particle detector with a high intrinsic time resolution of about $10~ps$ is being developed in BINP. The device must also has a high count rate, long lifetime in hard radiation conditions, large area of the sensitive surface and operate in magnetic field up to $4~T$. The suggested device consists of a Cherenkov light radiator ($MgF_2$), ultraviolet CsI-semitransparent photocathode and electronic amplifier based on MCPs. The production in vacuum installation of a semitransparent CsI-photocathode with deposition its at radiator from $MgF_2$ was mastered at BINP. The prototype has been developed and tested on test beam at BINP.
