HECTOR

High Energy g deteCTOR

( INFN Experiment: PARIDE)

HECTOR has been located at the Tandem Accelerator Laboratory of the Niels Bohr Institute at Riso in Denmark.

HECTOR is a detector array designed for the measurement of high energy gamma rays   (5 < Eg < 30 MeV) emitted by a hot rotating nucleus in the first steps of its decay.

The major field of use of HECTOR is in the study of the GDR decay

HECTOR is a collaboration between the I.N.F.N., the Niels Bohr Institute, and the Niewodniczanski Institute of Nuclear Physics

Hector consists of:

• 8 large (14 x 17 cm) BaF2 crystals

  • for the detection of high energy gamma-rays

• A multiplicity filter composed by 38 smaller (3" x 3") BaF2 crystals

  • for  the estimate of the nuclear spin and total energy by g-emission

• An HpGe detector

• An Isomer catcher

Later on, HECTOR has been moved to the I.N.F.N. Legnaro Laboratory and several other places in europe.
The first in beam test experiment has been performed on February 1999.
