The development and first results of the BST equipped with r strips are
published in NIM.

The role of the phi detectors in the BST and the physics aim of the FST
are described in proposals to the PRC.

One aim of the BST is to measure the momentum of backward tracks.

  • E / p comparison of momentum measured in the BST with SPACAL energy:
  • Another aim is to expand the measurement of heavy flavours into the backward direction.
    This is demonstrated by the decay of a J/Psi meson in the BST:

    The acceptance in x and Q2 for the detection of charmed particles
    is considerably enlarged by the new BST and FST:
