The experimental area 2 (EAR-2) at CERNs neutron time-of-flight facility (n_TOF), which is operational since 2014, is designed and built as a short-distance complement to the experimental area 1 (EAR-1). The Parallel Plate Avalanche Counter (PPAC) monitor experiment was performed to characterize the beam profile and the shape of the neutron flux at EAR-2. The prompt -flash which is used for calibrating the time-of-flight at EAR-1 is not seen by PPAC at EAR-2, shedding light on the physical origin of this -flash.

Evaluations are being done for the H(n,n), Li(n,t), B(n,), B(n,), C(n,n), Au(n,), U(n,f) and U(n,f) standard cross sections. Evaluations are also being done for data that are not traditional standards including: the Au(n,) cross section at energies below where it is considered a standard; reference cross sections for prompt -ray production in fast neutron-induced reactions; reference cross sections for very high energy fission cross sections; the U thermal neutron fission spectrum and the Cf spontaneous fission neutron spectrum and the thermal constants.
