Talks

The working groups 'Calibration', 'Readout and Data Transfer' and 'Electronics' had during the workshop combined parallel sessions. You can find the presentations of the combined sessions at A1.4 and A2.4.
The summary presentations of J.J. HERNANDEZ-REY and M. DE JONG(PDF format) or J.J. HERNANDEZ-REY (PPT format).

AIM OF THE SESSION:

      The calibration of the VLVnT heavily depends on its exact design and the technologies involved, so a close contact with the other groups is compulsory. Nevertheless, a broad classification of the calibrations needed in a VLVnT can be given and concepts and solutions discussed:

• Positioning
  • Internal calibration (among the detector components)
          Strongly depends on the design of the detector, but detector proposals with "moving parts" can benefit from already tested solutions based on sonic devices.
  • Absolute calibration (w.r.t. external references)
          This is a difficult and important issue to validate the actual angular resolution of the detector. New ideas are eagerly needed.
• Amplitude calibration
  • Heavily depends on the selected technology.
• Timing Calibration
  • Internal calibration
          Again heavily dependent on the precise design, but some general features can be defined before a design exists: calibration via the clock system, well-controlled light sources, etc
  • Absolute calibration (w.r.t. to UTC)
          Should not be a major problem.

        The program is focused on the review of technologies presently adopted in similar experiments and the investigation of new technologies that could be developed in the near future by industries or research laboratories for the detection of Cherenkov light in salt-water enviroments.
