Micromegas performance test for ( n , α ) measurements at n _ TOF : 33 S ( n , α ) cross section
نویسندگان
چکیده
Presently, a neutron detector based on the Micromegas concept is running at n_TOF facility at CERN for monitoring purposes. The main goal of the letter is a first (n,α) cross section measurement by using the Micromegas detector. The transmission of the sample and detector allow performing the experiment in parasite mode. In the future a series of (n,α) measurements would be performed at n_TOF of interest in several fields such as nuclear technology, astrophysics, medical physics and material science. We propose to measure the (n,α) cross section of the stable isotope S in the energy range from 0.1 keV to 100 keV. The possibility to cover a wider energy rage will be studied.

Cross section measurements for γ-process studies using a LEPS detector
In this paper we present the ongoing experiments at ATOMKI related to our systematic γ-process studies. These studies are intended to enlarge the limited experimental database from α-induced reactions on nuclei in the heavier mass range of the γ-process. In all presented cases the activation method was used. The details of the cross section measurements and preliminary results on In(α,n)Sb, In(...

The neutron-induced fission cross-section of U has been measured at the CERN n TOF facility relative to the standard fission cross-section of U between 0.5 and 20MeV. The experiment was performed with a fast ionization chamber for the detection of the fission fragments and to discriminate against α-particles from the natural radioactivity of the samples. The high instantaneous flux and the low ...

Background & Aims: Copper-61 (61Cu) is a radioisotope with a half-life of 3.33 hours which decays to nickel-61 isotope byβ+ emission (61%) or electron capture (39%). This radioisotope can be used in the evaluation of the blood supply of the heart and low-oxygen cancer tissues imaging with PET. 61Cu is mainly produced by bombarding zinc (Zn), nickel (Ni) and cobalt (Co) targets in medium cyclot...

The radiative alpha capture reaction cross section was measured from E c.m. = 16.09 MeV down to E c.m. = 11.21 MeV, close to the astrophysically relevant region (which lies between 7.8 and 11.48 MeV at 3 GK stellar temperature). The 162 Er(...
متن کاملFission Physics and Cross Section Measurements with a Lead Slowing down Spectrometer
A Lead Slowing Down Spectrometer (LSDS) provides a high neutron flux environment that enables measurements of small samples (∼μg) or samples with small cross sections (tens of μb). The LSDS at Rensselaer Polytechnic Institute (RPI) was previously used for fission cross section measurements and for studies of methods for assay of used nuclear fuel. The effective energy range for the LSDS is 0.1 ...
