The future international accelerator facility FAIR (Facility for Antiproton and Ion
Research) will host multiple experiments. A focus will be on experiments with antiprotons. The
PANDA (antiProton ANnihilation at DArmstadt) experiment will study the strong interaction in
annihilation reactions between an antiproton beam and a stationary gas jet target.
The PANDA detector consists of different sub-detectors for tracking, particle identification and
calorimetry. The Micro-Vertex Detector (MVD) as the innermost part of the tracking system will
facilitate precise tracking and detection of secondary vertices. The MVD will comprise hybrid
silicon pixel sensors and double-sided silicon strip sensors.
The strip part will contain approximately 200,000 channels that need to be read out using a highly
integrated front-end chip. Therefore, a custom-made ASIC is being developed. The self-triggering
PASTA chip (PAnda STrip Asic) will employ the Time-over-Threshold (ToT) technique to digitize
the hit amplitude and utilize time-to-digital converters (TDC) with analog interpolators to provide a
high-precision time stamp of the hit. A custom-made Module Data Concentrator ASIC (MDC) will
multiplex the data of all front-ends of one double-sided strip sensor towards the CERN-developed
GBT chip set (GigaBit Transceiver). The MicroTCA-based MVD Multiplexer Board (MMB) at
the off-detector site will receive and concentrate the data from the GBT links and transfer it to
FPGA-based compute nodes for global event building that combines all sub-detectors.

The PANDA experiment is a new hadron physics experiment currently being built at FAIR, Darmstadt (Germany). PANDA will study fixed-target collisions of antiprotons of 1 5 GeV/ c to 15 GeV/ c momentum with protons and nuclei at a rate of 20 million events per second. To distinguish between background and signal events, PANDA will utilize a novel data acquisition technique. The experiment uses a sophisticated software-based event filtering scheme involving the reconstruction of the whole incoming data stream in real- time to trigger its data taking. Algorithms for online track reconstruction are essential for this task. We investigate algorithms running on GPUs to solve PANDA’s real-time computing challenges

ToPiX v4 is the prototype for the readout of the
silicon pixel sensors for the Micro Vertex Detector of the
PANDA experiment. ToPiX provides position, time and energy
measurement of the incoming particles and is designed for
the triggerless environment foreseen in PANDA. The prototype
includes 640 pixels with a size of 100 um x 100 um,
a 160 MHz time stamp distribution circuit to measure both
particle arrival time and released energy (via ToT technique)
and the full control logic. The ASIC is designed in a 0.13 um
CMOS technology with SEU protection techniques for the
