WIENER “MARATON” POWER SUPPLY TESTS
• Introduction.
• Magnetic field tests.
• Plans for radiation and electrical tests.
• Conclusion.
Jan 29 2004 B.Allongue 2
Introduction
• The “MARATON” is a modular power supply:
– Input module.– Auxiliary power supplies and signals module.
No P, no control, no monitoring.
– Power modules.
• Same topology as TCC2 tests.• Water cooled

Radiation and electrical tests
• MOSFET Radiation tests:– Use of PFC implies bigger Vds:– Need to change the switching transistors.– Candidates tested in Irrad-1 facility at CERN.– Wiener is implementing the devices.– Tests campaign is foreseen 4 – 5 March 2004.

Radiation and electrical tests cont.
• AC/DC conversion box and monitoring box is expected end of February.
• Proceed to tests:– Noise– Length– …
Jan 29 2004 B.Allongue 27
Conclusion
• Magnetic test was performed in only one direction; additional tests should be done.
• Perform complete tests on the complete system.
• Get a functional system in spring 2004.
