1.) Scientific/Technical Approach
FRIB uses 0.5-2.5 Telsa strength magnetic dipoles to separate rare isotopes. Currently Hall probes are used to set B-field and then remove probe during operation to prevent damage. Gamma, neutron, and proton fluxes are about 2 E10 n/cm^2/s (mostly thermal neutrons).
If its mostly thermal neutrons then why not capture them with a liner?
Why do you need to monitor the B-field when beam is on?
Optical Frequency Domain Reflectometry will be used to measure B-field to an accuracy of 0.01%. Probes will be able to withstand fast neutron fluxes of 10^18n/cm^2 = 1 year in the FRIB.
a.) To what extent does the proposal build upon or extent current stat-of-the-art
b.) How new or unique is the idea
c.) Hos significant is the scientific or technical challenge
d.) Is a breakthrough possible
The propsal seek to develop a device to measure the magnetic field of a dipole (0.5 - 2.5 T)to an accuracy of 0.01% which can survive in a radiation environment with a neutron, gamma, and proton combined flux of 10^17 particle/cm^2/s. There is a statement that thermal neutrons make up most of the flux. There is little information on how much of the remaiing flux is from photons and protons thus it is difficult to determine if the device could be degraded from the radiation damage of the photons or protons.
