A warm liquid forward calorimeter for the SSC -- A new technology with challenges

PDF Version Also Available for Download.

Description

As part of the WALIC international collaboration, LBL engineers and physicists are building accelerator beamline prototype calorimeters using a room temperature ionizing liquid. If successful, this technology will be an immediate contender for the Forward Calorimeter of the Solenoidal Detector Collaboration (SDC), with potential application to complete, full scale SSC calorimeters. A 10 ton calorimeter using Tetramethylpentane as the ionizing liquid had been designed and built at LBL, and is now operating at Fermilab. In this unit, the TMP and ionization collecting electrodes are contained in stainless steel boxes'' interleaved with lead absorber plates; thus the TMP is in contact ... continued below

Description

As part of the WALIC international collaboration, LBL engineers and physicists are building accelerator beamline prototype calorimeters using a room temperature ionizing liquid. If successful, this technology will be an immediate contender for the Forward Calorimeter of the Solenoidal Detector Collaboration (SDC), with potential application to complete, full scale SSC calorimeters. A 10 ton calorimeter using Tetramethylpentane as the ionizing liquid had been designed and built at LBL, and is now operating at Fermilab. In this unit, the TMP and ionization collecting electrodes are contained in stainless steel boxes'' interleaved with lead absorber plates; thus the TMP is in contact only with the stainless steel container and a few small ceramic insulators. A second generation design, known as the swimming pool'' version, is under construction. A simplified configuration is used, immersing some 3600 lead absorber/electrode plates directly in the ionizing liquid. Challenges lie ahead in terms of liquid contamination (tens of parts per billion), voltage holding, and vacuum pumpout. 2 refs., 8 figs.
