---++ Test Report of Monday 25.06.2007
   
   * RB.A78
      * Provisional correction of the detection threshold of the bus-bar quench detector.
      * TF measurement - Test OK after some corrections done in one QPS crate
      * RB converter connected to the circuit
      * Circuit ramped up to 350A with the bus-bar quench detection threshold increased. Loop properly closed!
      * Some modifications needed in the QPS bus-bar quench detector - Circuit ramped up again to 350A with QPS in operational conditions!!
      * PCC Circuit Config - TEST OK!
     
   * RQF.A78 (6500A)
      * PLI3.2 - Energy extraction discharge - Test OK
      * PLI3.3 - Quench heater discharge on 12L8 SSS - Test OK

   * 600A Correctors
      * PCS tests on the circuits: RQT12.L8B1, RQS.L8B1, RCO.A78B1 - Going on
  
   * DFBMA refilled and cooled down in a couple of hours

   * 60A Closed Orbit Correctors: PCC in 16 converters

---++ Test Plan for Tuesday 26.06.2007

   * RB.A78
      * PIC2
      * PLI1 (760A)
         * PLI1.1 - Current cycle
         * PLI1.2 - Energy extraction discharge (quench to a current lead)
         * PLI1.3 - Powering Failure from PC
         * PLI1.4 - FPA from PIC
         * PLI1.5 - Quench heater discharge on LBBRG.10L8 (magnet 1030)
      * PLI2 (2000A)
         * PLI2.1 - Current cycle
         * PLI2.2 - Energy extraction discharge (quench to a current lead)
         * PLI2.2b - SPA from PIC
         * PLI2.3 - Quench heater discharge on LBBRA.13L8 (magnet 3002) and LBARA.13R7 (magnet 1054)

   * Matching Section: Powered to the same conditions of the triple quench on 31/06 once the quench detection threshold has been increased to operational values.
   
   * 60A closed orbit correctors: PCC and P2N

   * RQF.A78 or RQD.A78
      * Type tests
      * Quench campaign:
         * RQF and RQD ramped up together to 6500A. Quench TWO quadrupoles in different cryogenic cells simmultaneously.
         * RQF and RQD ramped up together to 6500A. Quench FOUR quadrupoles in different cryogenic cells simmultaneously.

   * 600A correctors
      * Study and debugging of the quench detectors going on.
