Target Optimisation Studies for the European Spallation Source

The European Spallation Source (ESS) is one of Europe’s biggest and most prestigious science projects. ESS will be the world’s most powerful next generation neutron spallation source for research with neutrons, providing a unique tool for studies of the atomic structure and dynamics of matter. In this paper we use GEANT4 simulations to investigate the effects of spallation target material and i...

The Spallation Target for the Ultra Cold Neutron Source Ucn

A source of ultra cold neutrons, based on the spallation process is under construction at PSI. With the help of a fast kicker the whole ~1 MW proton beam (590 MeV, 2 mA) from the accelerator will be switched onto the UCN spallation target for approximately 8 seconds every 15 minutes. The spallation neutrons are thermalized in a large heavywater moderator at room temperature and further cooled i...

Delayed neutrons measurement at the MEGAPIE target

In the framework of the Neutronic and Nuclear Assessment Task Group of the MEGAPIE experiment we measured the delayed neutron (DN) flux at the top of the target. The measurement was proposed mainly for radioprotection purposes since the DN flux at the top of the target has been estimated to be of the same order of magnitude as the prompt neutron flux. Given the strong model-dependence of DN pre...

Simulation of helium and residue production in the Megapie target

This work is aimed at characterizing the Megapie target in terms of main contributors to the activity, modification of the chemical composition as well as residue and volatile gas production. Calculations are performed with the nuclear transport code MNCPX2.5.0 coupled to the evolution code CINDER’90. In this work, we provide results for the lead-bismuth and its container. A sensitivity analysi...

postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
