A high-resolution beam imaging system was newly developed for pulsed muon beams in J-PARC MUSE using a plastic scintillator, a gated image intensifier, and a cooled CCD camera. The system was optimized for observation of 4 MeV muon beams and designed so as to be used with an existing muSR spectrometer in the D1 area, J-PARC MUSE. High-resolution beam profiles were obtained for a surface muon beam after exposure to the beam for several tens of seconds. A contribution from decay positrons was significantly suppressed by gating of the image ntensifier. Details of test experiments (negative muon beam profiles in the D2 area, 3D beam imaging, noise reduction, etc.) were presented.

Collinear laser spectroscopy is widely used to measure the isotope shifts and the hyperfine structures of unstable nuclei, from which the change of charge radii and the electromagnetic moments of these nuclei are deduced. However, radioisotopes of refractory elements have not been measured, because it is difficult to generate the ion beams necessary for collinear laser spectroscopy. Recently, SLOWRI has been constructed at RIKEN RI beam facility (RIBF), which can afford the ion beams of radioisotopes of all elements. We are developing a collinear laser spectroscopy setup at SLOWRI. We have confirmed that the reference values of the isotope shifts and the hyperfine structure constants of stable Ba isotopes were obtained. Since the intensities of radioisotopes are much lower than those of stable isotopes, improvement of sensitivity by using such as ion-photon coincidence is now in progress.
