Abstract
A proposed Very Cold Neutron Source (VCNS) would operate with 4 ms long pulses at 5 Hz and 1 GeV. The energy per pulse would be 300 kJ, much higher than the Spallation Neutron Source (33 kJ/pulse) or the present IPNS (0.3 kJ/pulse), and the peak power on target would be 75 MW. This paper discusses ideas for the VCNS target and examines the possibility of conducting target tests at an 8-GeV proton linear accelerator which is being studied for construction at Fermilab.
