Structure of experiment and the Experiment/Facility divide (some thoughts) Vitaly Pronskikh Fermilab 01/22/15

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. Т ph Meas Prep 3

Complex (accelerator-based) experiment • Tpr – instrumental theories of preparation • Tmeas – instrumental theories of measurement • Tanal – instrumental theories of data analysis Т ph det prot da Т pr1 Т pr2 Т meas Т anal ect ons ta or 4

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 of preparation, measurement and data analysis. 7
