Abstract :
A photomultiplier tube (PMT) based on avalanche photodiodes (APD) operating in the electron bombardment mode has been developed. The tube has a large linear dynamic range, moderate gain (5×105, and resistance to magnetic fields, and can be made with NEA photocathodes. This device will be useful for calorimetry at the Superconducting Super Collider where large dynamic ranges are required and other applications where high-quantum-efficiency photocathodes are needed. The extension of this concept to a multichannel device with a segmented APD array will provide a cost-effective fiber readout for both tracking and calorimetry applications. A tube equipped with such an array is being developed as a readout option for the Solenoidal Detector Collaboration Shower Maximum Detector
