Parallel readout of a photodiode array in a scintillating fibre calorimeter

In this paper results from a prototype calorimeter built in connection with the development of a new calorimeter for the H1 detector at the HERA collider are reported. The prototype was constructed as a lead-fibre calorimeter where the fibers were read out with an array of discrete photodiodes connected to conventional preamplifiers built with discrete electronics. Furthermore the first steps towards the design of the final detector setup are described. In particular the development of the integrated readout electronics for the calorimeter is considered.
