We introduce the recent development for increasing the performance of the SHARAQ spectrometer, which was operated at RI Beam Factory in RIKEN, Japan. The paper contains main achievements of our developments, which are detector developments, improvements of high-resolution performance at SHARAQ, and developments of new reaction probes to explore new kinds of nuclear responses. By using those new experimental technique, we recently performed various nuclear experiments at SHARAQ. We described here the preliminary results of the experiments together with their brief details.
