Past IN2P3/DSM accomplishments

Projects CLAS12

… European initiative towards the central detector …

Neutron detection at laboratory angles larger than 40°An efficient and fully exclusive study of the neutron-DVCS process Via the D(e,e’n)p reactionValence kinematics: x-Bjorken > 0.2

The neutron detection capability in the central region of CLAS12 is studied.

ToF scintillators

IPN Orsay / LPSC Grenoble / INFN / Glasgow

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

LPSC Grenoble / LPC Clermont Ferrand /JLab/ODU

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.
