The radioactive ion beams can be S022300100021 produced by using projectile fragmentation reactions S022300100022 at the RIBLL2. The 58Ni19+ ions were stored in the S022300100023 CSRe with an intensity of about 1E7 particles in each S022300100024 measurement cycle. S022300100025 SAMPLE A typical diameter of the gas-jet target is about 4 mm S022300100026 at the interaction point, the target density is about S022300100027 1012 atoms/cm2. S022300100028 DETECTOR (SI) In order to measure very low energy recoil S022300100029 protons, a single-sided silicon detector (SSSD) with S022300100030 a thickness of 300 um has been installed in the ultra- S022300100031 high-vacuum (UHV) chamber, which is connected to the S022300100032 CSRe. The SSSD with an active area of 48 x 48 mm2, S022300100033 mounted at a distance of 503 mm from the reaction S022300100034 collision point, covers the laboratory angular range S022300100035 from 85 to 90 deg for proton recoils. It was S022300100036 calibrated by using 207Bi, 239Pu, and 241Am S022300100037 radioactive sources. S022300100038 (SILI) To determine accurately the reaction S022300100039 luminosity, the k-shell x-rays from inner-shell S022300100040 ionization of 58Ni19+ ions, which were produced in S022300100041 the collisions with the H2 target, have been measured S022300100042 simultaneously with a Si(Li) detector. It is placed S022300100043 at 35 deg, at a distance to the collision point of S022300100044 488 mm. It was separated from the UHV environment of S022300100045 the CSRe by a 100-um beryllium window and collimated S022300100046 by a hole of 4 x 8 mm2. It was calibrated with 55Fe, S022300100047 109Cd, 133Ba, and 241Am radioactive sources. S022300100048 HISTORY (20201012R) Data received from Xiaolin Tu.
