Descripción
The International Fusion Materials-Irradiation Facility Demo Oriented Neutron Source (IFMIF-DONES) is a powerful neutron irradiation facility designed to study and qualify materials as part of the European roadmap to fusion-generated electricity. Its primary goal is to investigate the properties of materials under intense irradiation within a neutron field similar to that found in the first wall of a fusion reactor. IFMIF-DONES is a critical step toward the construction of the DEMO power plant, which is planned to follow ITER [1].
In addition to its core mission, IFMIF-DONES has expanded its baseline plant configuration to include facilities for complementary physics experiments independent of materials irradiation [2]. These additional experiments encompass: (1) applications of medical interest, (2) nuclear physics and radioactive ion beam facilities, (3) fundamental physics studies, and (4) industrial applications of neutrons.
The AANL has the potential to contribute to the (2), (3), and (4) domains mentioned above. This includes developments related to low-pressure MWPC-based fission fragment detectors [3-6], alpha-particle detectors [7, 8], and advanced radio-frequency timing techniques for single electrons and other scientific devices based on this new ultraprecise and ultrafast timing technology [9-11].
The experimental techniques described in publications [3-8] can be employed at IFMIF-DONES neutron beams for fission studies, low-energy nuclear physics experiments, neutron tomography in materials science and industry, and nuclear forensic analysis. Additionally, the developed ultraprecise and ultrafast RF timing technique [9, 10] can be utilized to create photon and neutron detectors for inertial fusion diagnostic studies and to measure the absolute energy of alpha particles with a precision of about 0.1 keV or better [11]. This proposed approach serves as an alternative to magnetic spectrometry and can help evaluate possible systematic errors. Furthermore, this table-top experimental setup can be used with the high-intensity neutron beams of DONES to conduct alpha spectroscopy of short-lifetime nuclear isotopes.
