Union of Compact Accelerator-Driven Neutron Sources (UCANS) I & II Calculations for ESS-Bilbao low energy target

ESS Bilbao is a research facility already in the initial construction stages that will host an accelerator-driven neutron source. It consists on a phased approach and its first phase considers the operation of proton beams accelerated up to 40 MeV, currents within 25 75 mA, and 20 Hz repetition rate with a 1.5 ms pulse length. Such accelerator parameters will allow a low intensity neutron-source to be configured with a power in the 30 90 kW range, and a neutron production close to 0.05 n/p. With these conditions, two rotatory target configurations are presented, one for low energy (30 kW) and one for mid energy (90 kW).
