F = 3/2 Increase from 2. 1 photons per atom to 1000 photons per atom, for a nominal SNR improvement of 20. F = 1/2 483 nm F = 1/2
Consistent with an SNR factor improvement of 17
In Ra-225 as well… Consistent with an SNR factor improvement of 17
Present: Copper Electrodes, E = 70 k. V/cm
At the level available with those upgrades, radium will improve significantly on the global sensitivity for all parameters
