Kinematics reconstruction in solenoidal spectrometers operated in active target mode
We discuss the reconstruction of low-energy nuclear reaction kinematics from
charged-particle tracks in solenoidal spectrometers working in Active Target
Time Projection Chamber mode. In this operation mode, reaction products are
tracked within the active gas medium of the Active Target with a three
dimensional space point cloud. We have inferred the reaction kinematics from
the point cloud using an algorithm based on a linear quadratic estimator
(Kalman filter). The performance of this algorithm has been evaluated using
experimental data from nuclear reactions measured with the Active Target Time
Projection Chamber (AT-TPC) detector

Breakup, transfer, and fusion studies of exotic “halo” nuclei using an active-target time projection chamber.
A program of study of the reaction mechanisms of exotic “halo” nuclei at energies near the Coulomb
barrier is described. The unique opportunities presented by the ReA3 reaccelerated beam facility at the NSCL, coupled with an active-target time projection chamber (AT-TPC), will be fully exploited in this program. An approximately half-scale “prototype” AT-TPC has been constructed and is currently undergoing tests. This device has recently been installed on the TwinSol [1] beam line at the University of Notre Dame, and preliminary results of reaction studies using a low-energy 6He beam are reported
The irradiation study of carbon stripper foils by a 12 MeV Ar beam
Irradiation performance of multilayer HBC foils which layers are more than 20 were conducted for the first time, and different types of carbon stripper foils were dosed under a series of irradiation conditions systematically. Eight (8) types of carbon stripper foils were striked by Ar4+ beam under different intensities and fluences. Multilayer foils performed generally better than the monolayer ones. The existence of boron layer helped to increase the resistance of the foils to irradiation damage, elongating their lifetimes
