Abstract

A photon tagging facility has been constructed for use with the c.w. electron beam at the Saskatchewan Accelerator Laboratory (SAL). The facility consists of a “clam-shell” type magnetic spectrometer with a 62 channel plastic scintillator focal plane detector allowing a post-bremsstrahlung electron energy resolution of 1%. Specialized focal plane and coincidence electronics have been designed and constructed at SAL and allows experiments to be performed with average tagged photon rates of greater than 1 × 108/s.

    The pulsed beam is injected into the MAX I stretcher ring [12] and subsequently slowly extracted to obtain an almost continuous beam at the tagging facility, where it impinges on a thin aluminum foil to produce bremsstrahlung photons. The energy of the post-bremsstrahlung electrons is analysed in one of two magnetic spectrometers, previously used at the Saskatchewan Accelerator Laboratory [13]. In the present measurement the so called main tagger (MT) magnet was used.

    Such dead-time corrections are difficult for modern high-count-rate experiments as they rely on a knowledge of the instantaneous photon flux which may or may not be constant. Experiments that use photon tagging (for example Refs. [2–5]) count the number of post-bremstrahlung electrons striking a focal plane detector. This may be related to the number of photons reaching a target by applying a measured ‘tagging efficiency.’
