CALB-DET=/ Velocity calibration was performed using the 240 MeV 127I
beam to bombard thin (70-100 micro-gram/cm2) calibration
targets, natAg, natIn, natSb, and 209Bi. Each target was
evaporated on 30 micro-gram/cm2 thick carbon foils. The
recoil nuclei and the elastically scattered 127I ions were
detected with the present ToF system. /;

- Time-of-flight (To measure fission fragment velocities)
- Beam current integrated (The average beam current was 500-800
