1. TEC Ring 2 module prototypes J. Hrubec / Inst. für Hochenergiephysik
HEPHY - VIENNA
TEC Ring 2 module prototypes
First 4 prototypes with Dorazil hybrids (6 APV’s) ready to form
Ring 2 of one TEC petal
Ring 2 normal
Ring 2 stereo
Testing : I - V Curves, Tests with ARC System,
3 passive thermal cycles down to about -20 degrees.
Results before and after this cycling are consistent

Next steps
3 pairs of final hybrids already in Vienna
No bonding problems expected with shorter spacers for
the pitch adapter
Need to adapt assembly plates and bonding platform to
new frame design
Final automatisation for insertion of data to the
database
Implement Aachen HV unit to the ARC test system
