Collider experiments require challenging detectors and data acquisition electronics. The PANDA experiment, currently under construction at GSI in Darmstadt, will be one of the major experiments at the Facility for Antiproton and Ion Research (FAIR). The PANDA collaboration, with more than 400 scientists from 18 countries, intends to do elementary physics research on various topics like weak and strong forces, exotic states of matter and the structure of hadrons. The PANDA detector is composed of several detector layers. The detector closest to the interaction point, designed for precise reconstruction of primary and secondary vertices of the interaction, is the Micro Vertex Detector (MVD). It is made of silicon pixel and microstrip sensors and it will use custom front-end electronics to readout the data. Each microstrip detector module will be equipped with front-end chips as well as one digital Module Data Concentrator (MDC) ASIC. The MDC serves as link between the frontend chips and the data acquisition (DAQ) system. The chip will be placed on the detector module inside the active area. It will read out one double-sided strip sensor by multiplexing the data stream of all front- ends chips. Besides the readout, the MDC ASIC will also decode and multiplex the front-end chip data, implements the data transmission to the DAQ system via serial LpGBT/XGBT links and provides slow control functions (parameter settings, monitoring).

Job description

This PhD thesis will focus on the design and development of the MDC ASIC for the local control of the microstrip detector modules of PANDA. Since it will be located in the same radiation environment as the front-end chips, Single Event Upset (SEU) mitigation techniques like triple redundancy will be employed for all critical components. To satisfy the requirements on radiation-hardness, the chip will be developed in 110 nm UMC CMOS technology.

The PhD project pursues the following objectives:

  • Development of the MDC architecture on field programmable gate logic (FPGA) and validation of the logic behavior. In a first step, the entire MDC logic will be implemented in a FPGA and connected to the detector front-end chips. The functionality and performance of the design are evaluated.
  • Design, production and test of the first prototype MDC in 110 nm UMC technology.
  • Design of the final MDC as ASIC making use of libraries for radiation- hardness with majority triple-vote logic to mitigate the SEU.
  • Irradiation test of the MDC and characterization of radiation effects.
  • Production and final test of the ASIC that will be integrated in the microstrip detector modules.
  • There are many aspects of this project, which all require in-depth R&D. This includes advanced design and production of complex digital ASICs for modern microstrip detectors, the implementation of radiation tolerant logic and of high-speed communications, etc. The PhD project will be carried out at the Institute of Data Processing and Electronics (IPE) at KIT. Commissioning will require regular trips to GSI. The research plan includes the design of electronics, test & validation, and commissioning at the PANDA detector. Throughout the project the results will be presented to the PANDA collaboration. Supervision of bachelor and master students, presentations at scientific conferences, and publication in high-impact journals is expected.
