Experimental facilities available at ALTO:

BEDO BEta Decay studies at Orsay

BEDO (BEta Decay studies at Orsay) is a state-of-the-art movable-tape-based experimental setup currently operated at ALTO. The opportunity to build a more complex detection system was offered by the completion of a new set a secondary beam line sections at ALTO. The BEDO setup is dedicated for nuclear structure studies after beta decay of neutron rich fission isotopes produced at ALTO. Nuclei in the mass region of N=50 and close to the Z=28 shell closure have attracted many experimental and theoretical interest at BEDO.

Neutron detector TETRA

TETRA is an 3He based neutron counter was built in Dubna in 1981 and installed in ALTO in 2009 through a bilateral IPN-FLNR collaboration. It is made of 90 different gas cells encapsulated in a hexagonal polythylene structure. At ALTO, this setup is dedicated to the measurement of the probabilities of neutron emission with the aim to reveal nuclear structure modifications in isotopic chains when crossing shell closures, but also because these probabilities in very neutron rich nuclei are important inputs for modelling the rapid neutron capture process.
The TETRA integrated data acquisition system is designed to make TETRA a tool of choice for detection of high multiplicity neutron events. This feature will be important for the upcoming experiments with beams of neutron rich-nuclei for which larger Qβ values result in higher multi-neutron emission probability. We have also demonstrated the ability of TETRA to be used as neutron trigger for β-decay g-spectroscopy despite the inherently slow neutron registration process. A new digital DAQ will be used and the signal of every single 3He cell among the 80 cell will be recorded in a trigerless mode.

COeCO COnversion electrons Chasing at Orsay

COeCO is the most recent addition to the BESTIOL master project. It consist od a decay station for β-delayed conversion electron spectroscopy. The setup is based on two magnetic coils allowing to guide the electrons to a SiLi, LN2 cooled detector placed further from the implantation point to minimize the impact of β in the conversion electron spectrum.
