| Laser control system for scintillation calorimeter | ||
| Protvino, 1999.-p.17, figs.13, tables 1, refs.:13. | ||
A 780 channel laser control system for scintillation hadron calorimeter is described. It consists of a nitrogen laser, neutral filters (7 steps of attenuation), an electromechanical commutator that distributes light among calorimeter layers, light fan-outs, control electronics and quartz fibres. The system was studied during a beam test of a calorimeter. The precision of the laser signal pulse measurements was equal to 1% with the system stability is being 1.1%.
