4 Resources for Hardware Commissioning basic assumptions programme of the tests sequence of the tests time needed for each test inventory of the test teams and their composition This document presents the resources identified for a commissioning scenario restricted by a number of assumptions: in particular, the parallel commissioning of two sectors around an even point -not more and not less- and the staggered commissioning of an additional set of two sectors where the cool down follows the of the first set. However from the data presented in this document, it is possible to derive the resources needed for a different scenario when some of the restrictions are lifted or relaxed. Resources for Hardware Commissioning basic assumptions programme of the tests sequence of the tests time needed for each test inventory of the test teams and their composition 1. Two sectors at a time around an even point 2. Five-day working weeks 3. Two shifts during 4. Two commissioning fronts per sector 5. The magnets are left floating in temperature after the commissioning 6. The RF system is commissioned just before commissioning with beam 7. The PS and SPS complex run in

5 Management Report : RESOURCES FOR HARDWARE COMMISSIONING basic assumptions programme of the tests sequence of the tests time needed for each test inventory of the test teams and their composition 1. Tests at warm validation of subsystems, connectivity, computer networks and filed buses, timing, supervision, etc. validation of the instrumentation and subsystem functional tests electrical quality assurance short circuit tests, interlocks 2. Cool down calibration at cold and cryo loop tuning electrical quality assurance 3. Tests at cold electrical quality assurance quench protection 4. Powering Tests validation of the interlocks validation at low, nominal current and all circuits in unison The resulting schedule tests at cold weeks right of the even point 8weeks left of the even point 23 weeks 5

6 Parallelism as per basic assumptions 28 months the adjusted overloading only the Operator,, HC Coordination and Cryo Operation Teams specified in the report 20 months The resulting need for resources with the basic assumption The personnel involved in the individual system tests and the hardware commissioning 142 of which 46 are missing. Additional budget for IS and FSU is MCHF.

7 Report Summary with the basic assumption ~20 months 142 people involved 46 missing in some cases experience is a must engineers and technicians cryogenics quench protection interlocks coordination & operation controls possible sources national institutes but also recruitment staff for supervision is already critical training of new resources for commissioning is critical what do we do with the Report? convince Management this is serious find additional resources study alternatives strategies alternative to personnel directly under the supervision of the Groups partial commissioning of the sectors review the commissioning procedures 7

10 Sector 78 : installation sequence as planned key dates 13 June October October March 2006 QRL test LSS subsector partly in parallel with QRL test of whole sector power tests of LSS subsector partly in parallel with QRL test of whole sector power tests of LSS subsector must end by 10

11 the sector test in in summary the work on documentation is close to the end domains studied and documents started or published feasibility of the computer assisted progress follow-up and storage of test results the priority for 2005 is the detailed program for sector 78 and the preparation for the deployment of the teams in the field the Hardware Commissioning of LSS L8 (String 3!) the time available for commissioning has been constantly reduced over the past year without compensating it with adequate resources 2005 is promising to be a very interesting year 11
