Description
It is planned to install a disc DIRC counter in the WASA experiment
at the COSY proton storage ring in Juelich. The purpose of this counter
is to improve for 400 MeV to 800 MeV protons the kinetic energy measurement
in the forward direction, measuring their speed at the few per mille level.
The disc DIRC is to be placed downstream of the WASA tracking counters
in front of stacked plastic scintillator blocks that with a dE/dx profile
continue to provide the particle identification.
The segmentation into four quarter-discs allows to incline the radiator
relative to the incoming particles and thus lower the threshold velocity
for light propagation inside the DIRC radiator.
It is planned to prototype two disc DIRC versions, a focussing DIRC
and a time-of-propagation DIRC. The construction of two full-scale
quarter disc prototypes is foreseen for 2010.
With the view of prototyping DIRC detectors in WASA for the
upcoming PANDA experiment, we aim to validate the simulation results
and gain experience in operating such a detector type in a hadron machine.
