The Solid State detectors Lab proposes various technologies for their realization and shows the construction and working principles of real detector systems. The activity is structured as follow:

  • Day 1: The Silicon Drift Detectors for precision X-ray spectroscopy, with application to exotic atoms measurements, will be introduced; a prototype containing a few SDD elements will be shown and its components (DAQ, Slow Control, readout electronics) presented in detail; a data taking with an X-ray tube or with radioactive sources will follow and preliminary X-ray spectra will be visualized.
  • Day 2: The X-ray spectra obtained during Day 1 will be analyzed and the linearity of the SDD detectors extracted; another data taking in different conditions with respect to Day 1 (higher counting rate) will be performed and the spectra analyzed; the SDD part of the laboratory will end with discussions and conclusions.
  • Day 3: By using a Coordinate Measuring Machine the students will assemble detector modules of the future Inner Tracking System of the ALICE-LHC detector. The modules will be assembled with a precision smaller than 10 µm, a micro-soldering will connect the modules to the power-bus and an electric test will complete production chain.
  • Day 4: Monolithic Active Pixel Sensors (MAPS) test at the Beam Test Facility.

Solid State Detector Systems: construction, working principles and characterization

Solid State particle detectors are broadly used in atomic, nuclear and high energy physics experiments, as tracking detectors or for high-precision spectroscopy measurements. Due to their high rate capabilities, extremely low material budget and microscopic pixel sizes, these detectors are more and more used in experiments where both the particle rate and the required precision of the impact point is very high, like the LHC experiments. On the other hand, the Solid State Detectors are able to perform very high precision X-ray spectroscopic measurements, and are used in many atomic, nuclear and particle physics experiments, as well as in many other fields, such as medicine, biology and industry.

The aim of the exercise is a hand-on activity on two different types of detectors: the MAPS (Monolithic Active Pixel Sensors) and the SDD (Silicon Drift Detectors) for spectroscopic use. The laboratory will give an overview of the construction process for these detector systems including a characterization using the Beam Test Facility with an electron beam of ~500 MeV (for the MAPS detectors) and an X-ray tube and/or radioactive sources in the laboratory (for the SDD detectors).
