Cross Section Measurements Using the Zero Degree Detector

The Zero Degree Detector (ZDD) is an instrument that has been used in accelerator expo- sures to measure the angular dependence of particles produced in heavy ion fragmentation experi- ments. The ZDD uses two identical layers of pixelated silicon detectors that make coincident meas- urements over the active area of the instrument. The angular distribution and multiplicity of secon- dary particles produced in nuclear interactions of heavy ions and target materials will be presented along with performance characteristic of the instrument.
