Antonio Perin (AT-ACR)12/05/2005, 10:35slidesThe DFBs, DSLs and connection cryostat, once installed and connected, form an integral part of the magnet powering scheme as well as the cryogenic system. This is reflected in the hardware commissioning. The test activities comprise: pressure and leak tests, high voltage tests (warm, before and after connecting and cold), instrumentation checks, control procedure validation...Go to contribution page

Suitbert Ramberger (AT-MEL)12/05/2005, 11:05Hardware commissioning of the magnet systems comprises the test of its individual components as much as their interaction within the system. Only the latter operation shall be addressed in the Hardware Commissioning Review. The tests of the magnets are therefore discussed as a pre-requisite. On this basis, their initial state is defined and shall be taken into account for the...Go to contribution page
