Description
PANDA is a detector under construction dedicated to studies of
production and interaction of particles in the charmonium mass range
using antiproton beams in the momentum range 1.5 – 15 GeV/c which will
be available at the Facility for Antiproton and Ion Research in
Darmstadt. PANDA consists of two
spectrometers – the Target Spectrometer based on
a superconducting solenoid and a Forward Spectrometer
using large dipole magnets and covering the most forward scattering
angles (Th<10o). In both spectrometers,
the deflection of particles trajectories in the magnetic field is
measured using self-supporting straw tube detectors.
The expected high count rates reaching up to 1 MHz are one of the main
challenges for the
straw tubes and associated read out electronics.
In the talk, the design of the tracking system and the results of a
test of the prototype straw tube tracker equipped with a read out
chain will be presented.
The latter consist of a newly developed ASIC with amplification,
signal shaping, tail cancellation, discriminator stages and
digital boards -Time ReadOut Boards- with
a TDC implementation based on an FPGA featuring time over threshold
measurements and fast GbE optical links for the data transmission.
