Description
I will introduce low-energy electron scattering facilities for nuclear physics that we have constructed in Japan.
1) the ULQ2 facility at Tohoku for the proton radius
Ee = 10 - 60 MeV, \theta_e = 30 - 150 deg..
high-resolution twin spectrometers with 4k-ch silicon strip
detectors.
2) the SCRIT facility in RIKEN/RIBF for short-lived exotic nuclei.
the world’s first electron scattering facility dedicated to short-
lived exotic nuclei.
Ee = 150 - 300 MeV, q = 80 - 300 MeV/c.
Luminosity ~ 10^{27} /cm2/s with N_RI ~ 10^8/s.
ISOL (Photofission), electron storage ring, large-acceptance
spectrometer.
After introducing the facility details and current status, I will discuss a new physics case, recently we pointed out, at such low-energy electron-scattering facilities.
