- | The intermediate image box (see (picture) Fig. xxx) is equipped with two Tracking Parallel Plate Avalanche Counters (TPPACs) . | + | ===== Operation |

- | + | ||
- | A much larger scattering chamber (see (picture) Fig. xxx) is available to accommodate for bigger detector systems such as HiRA. This chamber retains a target mechanism similar to the one described above (vertical translation + rotation), but with the additional possibility of shifting the target position along the beam axis. This feature is necessary for experiments that require more space " | + | |
- | + | ||
- | As mentioned before, the scattering chamber is equipped with drives that can accommodate any kind of tracking detector (with a small adaption). Standard PPAC detectors (limited to 1 kHz count rate) can be installed at those locations. However, one should keep in mind that reaction products stemming from interaction of the beam with the detectors pose a possible contamination of the beam and require " | + | |
- | + | ||
- | Some detection systems do not require a scattering chamber. In this case, the chamber will be removed and the target is slid into a pipe surrounded by the detector array. SeGA, CAESAR, GRETINA, PLUNGER, LENDA have standard frames and setups to be used with the S800. Other detector arrays would require the design and fabrication of new hardware. In this configuration a target change presently requires venting the target section and dismounting part of the hardware to access the inside of the beam pipe. This operation typically takes about 30-45 minutes. | + | |
- | The S800 focal plane box (see (picture) Fig. xxx) is equipped with various detectors including two position sensitive Cathode Readout Drift Chambers (CRDCs) for tracking the trajectories of the particles, a ion chamber for the measurement of energy loss, a timing scintillator | + | |
