(some thoughts)

Outline

• Structure of classic experiment
• Structure of complex contemporary experiment
• Possibilities of the Experiment/Facility

demarcation

• Summary

2

Classic experiment

• Galileo acceleration experiment, inclined

plane experiment

• Tph- theory of phenomenon
• Preparation, measurement – operations.
• Balls did not require instrumental theory.

Summary

• The operational scheme suggests that current division

between the collaboration and the facility (despite technically necessary) seems to be just one possibility (from the viewpoint of knowledge production) and in principle can be supplemented by two additional ones: between detectors and counters (triggers), and between data production and analysis.

• Nevertheless, in order to be consistent with the classical

model (as theory is), interests and activities, the scope of an experimental collaboration needs to comprise all stages

• f preparation, measurement and data analysis.
