Description
The single crystalline Chemical Vapour Deposition (scCVD) diamonds have found applications in numerous fields in experimental physics including beam diagnostic, beam monitoring and time measurement of charged particles with picosecond precision.
It has been demonstrated that scCVD diamonds can be used in single particle counting mode for MIPs with the picosecond precision. These detectors can also be used for high precision particle tracking.
To demonstrate these capabilities a dedicated experiment has been performed at COSY-Juelich Synchrotron with protons of 2.9 GeV. A scCVD sensor with relatively simple electrode configuration has been used as a reference detector for a straw tube test and delivered excellent performance in terms of time precision and position determination. The sensor, which has been developed for the HADES experiment, can measure particle rates (MIPs) up to 10 MHz/mm^2 with time precision better than 100ps and additionally the position resolution better than 50 micrometers can be obtained. Such device can significantly simplify the test setups for detector performance tests.
The presentation will focus on the operation of the scCVD diamond in single particle mode for MIPs with the picosecond precision and at the same time tracking capabilities with position resolution better than 50 micrometers. The performed test experiment will be presented in details.
