-ray beam in the next generation"Fujiwara, Mamoru
no journal, ,
We organize the symposium titled "Perspectives of Laser-Compton-Scattering (LCS) high-intensity -ray beam in the next generation" in the Kochi JPS meeting held on 20-23 September 2013. In this symposium, several important talks are scheduled from both the physics and accelerator sides. One of key important ingredients to deliver a high-intensity LCS ray beam is the Energy Recovery Linac (ERL) developed by JAEA. I give a summary talk of this symposium and show some scientific perspectives realized in future.

It has been expected that non-uniform structures called pasta structures appear in neutron star crust. Recently, the studies of giant flares from magnetar suggest that pasta structures might influence the observables and mechanical properties, such as shear modulus, of neutron star crust. We have explored the ground state structure of neutron star crust by relativistic mean field model and Thomas-Fermi model without any assumption about the geometry. By using the data of these structures and inflicting the deformation, we obtained the shear modulus. We will present the state of progress about the study of shear modulus of neutron star crust.

J-PARC E42 is an experiment to search for the H-dibaryon in (
,
) reactions. The experimental setup consists of a larget solid angle TPC, a Helmholtz dipole magnet, and a spectrometer (Kurama). We have performed an experiment of a prototype TPC injecting a UV laser under magnetic field with the FM magnet in the J-PARC hadron facility hall. We have been also developing the second TPC which has the real size the pad plane and GEMs. In this presentation, we report the results of the prototype TPC and the status for the second TPC.

In 1950's, Agodi predicted that the neutron angular distribution in (, n) reactions with a 100% linearly polarized -ray beam for dipole excitation should be anisotropic and universally described by the simple function of a + b
cos(
)at polar angle 
=90
, where 
is the azimuthal angle, but it has not been experimentally confirmed over half a century. The work by Agodi had been forgotten after 1970's. We have verified experimentally this angular distribution on three targets using linearly polarized laser Compton scattering -rays at NewSUBARU for the first time.
