DATA ACQUISITION

Questions of the Referees:

-----------

1. What type of DAQ programs will be used (CERN-provided, self- written, others)?
2. Which real-time operating system will be used (OS-9, Lynx, others)?
3. What type of CERN support is expected?

-----------

In this section we focus on some additional details of the data acquisition system for COMPASS. We mostly deal with the level of large spill buffers in VME along with CPUs to control them and the level of the DAQ machine. Furthermore the question of the possibility of a central data recording scheme is raised. The collaboration is in contact with the CN and ECP division to discuss in more detail issues raised in this section.

• Schedule for the design and tests of the DAQ
• DAQ programs
• Real-Time operating systems
• Support by CERN
