Results from the tests of the T600 detector
Interactions of cosmic rays detected by one of the module of the T600 detector in 2001 in Pavia. This picture shows examples of hadronic interactions and an electromagnetic cascade. |
The main conclusion from the tests is that the measurements and the experimental results demonstrate that it is feasible to master all technical issues related to the construction and operation of a large size LAr TPC, within and sometimes beyond the design specifications:
- LAr handling and purification
- wire chambers mechanical construction
- HV system for the electron drift
- electronic noise
- scintillation light detection
- triggering, read-out and data handling
- detector monitoring and control
The above-ground location of the experimental site in Pavia allowed the collection of a large sample of cosmic ray events recorded with different configurations of dedicated trigger systems: an external trigger system, internal PMT's system and combined trigger logic between internal and external systems.
