 1     Final approval of provisionally approved circuits for sector 4-5. (Andrzej/Mirko,...).

The powering testing status can in principle be seen from the hardware commissioning pages with address http://p2n.web.cern.ch/p2n/default.php?search_psect=S45 . The last test (PIC2 GLOBAL PROTEC. MECH) mentioned in this series is however a collective test. Approval of a single circuit could therefore be given if all tests except this one had been made. The steps in this status report correspond to the steps in the engineering specification in the test program and have each to be approved by the MPP responsible. It was remarked during the meeting that getting the data for analysis of each step was not easy.

It was decided that Nuria would try to make to make a systematic step by step analysis of Q5.R4. This in order to gain experience and help define our needs for more automatic data analysis.

 

 2    Present Circuit Non-Conformity status in sector 4-5 (Rob, Nuria).

There is still a non conformity open on circuit RCBYV5.R4B1 ( MCBY corrector short-circuited at 300V at warm in Q5R4, EDMS 842369, V. Chareyre). This corrector is important for the machnine.

A voltage test (600V) has still to be made to test this circuit (see slides) after which we have to decide if we test this circuit. Note that  the magnet does not have a protection resistor. Therefore if the busbar burns the magnet can be destroyed.
