KVINTA Setup
"Центр Физико-Технических Проектов“
"АТОМЭНЕРГОМАШ"
Set-up: Natural uranium target: rods with Al cladding total weight 315 kg (500 kg)
Sometimes lead box is used: bricks 1780 kg
Main objectives:
1)
To have „simple set-up for benchmark studies of neutron production and
transport simulation codes (for example MCNPX code).
2)
Systematic of deuteron beams with energies higher then 1 GeV.
3)
Measurement of neutrons and delayed neutrons during low intensive
beam
4)
Activation and track detectors
5)
To obtain strong source of neutrons for transmutation tests

Three different energies: 2 GeV, 4 GeV and 6 GeV – low and high intensity run
irradiation time – around 20 hours
Aluminum and copper beam monitor foils
Deuteron beam 2 GeV, 4 GeV and 6 GeV

Transnational Access Activities
The ERINDA project is an Integrated Infrastructure Initiative (I3) funded
under the 7th framework programme (FP7) of the European Commission.
The ERINDA Project
Start date: 1/1/2011
Duration : 4 years
Beam time: 2600 hours
Typical experiments: 26
Support: 80 manweeks
The ERINDA Consortium
13 partners- 13 facilities
hours for external users
