Measurement of the $^{235}$U(n,f) cross section relative to the $^{10}$B(n,α) reaction with Micromegas detectors at the CERN n_TOF facility: First results / n_TOF Collaboration
Neutron cross section measurements are often made relative to a neutron cross section standard. Thus, the accuracy of the neutron standards determines the best possible accuracy of the neutron measurements. [...]

Development of an Ionization Chamber for the Measurement of the$^{16}$ O(n, ${\alpha }$ )$^{13}$ C Cross-Section at the CERN n_TOF Facility / Urlass, Sebastian (TU, Dresden (main) ; HZDR, Dresden ; CERN) ; Junghans, Arnd R (HZDR, Dresden ; CERN) ; Hartmann, Andreas (HZDR, Dresden) ; Mingrone, Federica (CERN) ; Sobiella, Manfred (HZDR, Dresden) ; Stach, Daniel (HZDR, Dresden) ; Tassan-Got, Laurent (CERN) ; Weinberger, David (HZDR, Dresden) /n_TOF Collaboration
The$^{16}$ O(n,  ${\alpha }$ )$^{13}$ C reaction, as the inverse reaction of the astrophysically important$^{13}$ C( ${\alpha }$ , n)$^{16}$ O reaction, is proposed to be measured at the neutron time-of-flight (n_TOF) facility of CERN. To this purpose, a Double Frisch Grid Ionization Chamber (DFGIC) containing the oxygen atoms as a component in the counting gas has been developed and a prototype was constructed at Helmholtz-Zentrum Dresden-Rossendorf(HZDR), in Germany. [...]

Data for the s Process from n_TOF / n_TOF Collaboration
A considerable amount of (n, $\gamma $ ) reactions has been studied, so far, at the neutron time-of-flight facility n_TOF at CERN. The experimental program aims at determining and improving cross sections for a number of isotopes relevant to s-process nucleosynthesis. [...]

Measurement of the $^{16}$O(n, α)$^{13}$C cross-section using a Double Frisch Grid Ionization Chamber / n_TOF Collaboration
The $^{16}$O(n, α)$^{13}$C reaction was proposed to be measured at the neutron time-of-flight (n_TOF) facility of CERN. To this purpose, a Double Frisch Grid Ionization Chamber (DFGIC) containing the oxygen atoms as a component in the counting gas coupled with a switch device in order to prevent the charge collection from the so-called γ-flash has been developed at Helmholtz-Zentrum Dresden-Rossendorf (HZDR), in Germany. The first $^{16}$O(n, α)$^{13}$C measurement without seeing the charge of the γ-flash at n_TOF has been performed in November 2018. [...]

First Results of the $^{140}$Ce(n,$\gamma$)$^{141}$Ce Cross-Section Measurement at n_TOF / n_TOF Collaboration
An accurate measurement of the $^{140}$Ce(n,$\gamma$) energy-dependent cross-section was performed at the n_TOF facility at CERN. This cross-section is of great importance because it represents a bottleneck for the s-process nucleosynthesis and determines to a large extent the cerium abundance in stars. [...]

U., Athens) ; Weinberger, David (HZDR, Dresden) /n_TOF Collaboration
The development of a switch circuit to gate charge sensitive preamplifiers for use at pulsed radiation sources will be presented. This development was used for the $^{16}$O(n,$\alpha$)$^{13}$C reaction measurement with a Double Frisch Grid Ionization Chamber (DFGIC) at the neutron time-of-flight facility CERN n_TOF in Geneva, Switzerland.

U.) ; Schwengner, Ronald (HZDR, Dresden) ; Wagner, Andreas (HZDR, Dresden)
In a fast neutron spectrum essentially all long-lived actinides (e.g. Plutonium) undergo fission and thus can be transmuted into generally short lived fission products. [...]
