Jan B.Allongue1 WIENER “MARATON” POWER SUPPLY TESTS Introduction. Magnetic field tests. Plans for radiation and electrical tests. Conclusion.
Jan B.Allongue2 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
Jan B.Allongue3 Introduction cont. Power double modules: 2 7 V 50A 2 * 250 W V 6A 2 * 300 W Tests: 3 outputs 5 V / 100A 500 W 1 output 3.3 V / 200A 660 W 1 output 48 V / 12A 576 W Nominal output power : 2736 W

Jan B.Allongue23 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.
Jan B.Allongue24 Radiation and electrical tests cont. Tests set up for irradiation:
Jan B.Allongue25 Radiation and electrical tests cont. Electrical tests: Power module Control and Monitoring Hostile zone Radiation + B field Protected zone Power supply box Aux PS Power module PFC
Jan B.Allongue26 Radiation and electrical tests cont. AC/DC conversion box and monitoring box is expected end of February. Proceed to tests: –Noise –Length –…
Jan B.Allongue27 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.
