The COMPASS collaboration expects to profit from the various ongoing R&D projects at CERN aiming at the development of components for a high rate DAQ system for LHC. Support for the modification of the design of the GASSIPLEX chip (RD26) is requested. Furthermore we are interested in the developments of readout electronics for microstrip detectors by RD20 and calorimeters by RD16, which are partly also taken up by experiments outside CERN (e.g. HERA-B).
In addition, exchange of information with R&D projects on triggering
(RD11, RD12), data transfer (SCI: RD24) and eventbuilding (RD31)
CERN already provides OS9 and Lynx support, and most likely will continue
to do so. COMPASS would like to profit from the experience gained with
these operating systems at CERN.
The COMPASS collaboration is prepared to provide a data recording system using high speed, high capacity tape media as outlined in the proposal, if it will prove necessary. However we would very much appreciate to cooperate with CERN to set up a scheme for central data recording as currently implemented for NA48. This scheme, widely used at other HEP laboratories, would have several advantages in comparison to the standalone option:
