Abstract:In this paper we present a timing pickup detector used at Radioactive Ion Beam Line in Lanzhou (RIBLL). It has low detection threshold and is radiation-resistant. The photons induced by radioactive beam ions passing through a thin plastic-scintillator foil, east from the foil center corresponding to one focus point of a aluminum ellipsoidal mirror and are reflected to another focus point at which the cathode of a photomultiplier tube locates. The readout pulse signals were sent into a CAMAC's TDC module. A time resolution of about 140ps is achieved and the counting face up to 108pps is allowed.
Keywords:RiBLL  ellipsoidal mirror focusing  time of flight (TOF)
