The main question is the reliability and feasability of ToF measurements in the current configuration involving short flight paths, small energy deposit, and magnetic field.
Bench Test @ Orsay
Neutron Detection @ CLAS12

The possibility of a high intensity polarized positron source is investigated.
The design is based on a low energy (5-10 MeV) highly polarized (100%) and intense (1-10 mA) electron beam: In a radiator, longitudinnally polarized electrons create via Bremsstrahlung circularly polarized photons which transfer their polarization to positrons via pair-creation.
Preliminary simulations indicate that one may create a beam of up to 10 nA within the CEBAF admittance, with ~50% longitudinal polarization.
A test experiment is being designed for the CEBAF injector.
• Validate the concept• Measure the angular, energy
and polarization distributions of positrons.
