# Target Considerations for a Very Cold Neutron Source

## TL;DR

This paper explores the design and feasibility of a Very Cold Neutron Source with high-energy pulses, discussing target concepts and testing possibilities at Fermilab's proposed 8-GeV proton accelerator.

## Contribution

It introduces ideas for a VCNS target and evaluates the potential for conducting target tests at an 8-GeV proton linear accelerator.

## Key findings

- High pulse energy and peak power requirements identified
- Feasibility of target testing at Fermilab's proposed accelerator examined
- Design considerations for VCNS target discussed

## 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.
