MARATON hazardous HE

MARATON is a family of MAgnetic field and RAdiation TOleraNt power supplies developed for CERN LHC. MARATON HHE is the 12 channel version for use in a hazardous hostile environment.

Magnetic field tolerance is achieved by water cooling (up to 300G) and shielded components (up to 1200G). For radiation hardness (<30Gy) a quasi-redundant principle of power conversion is combined with special components. Further radiation sensible components are placed at remote locations.

The modular construction with a 19" rack mountable power bin and a plug-in power supply box allows to swap the power supply without any tools and within shortest time.

Dynamic:

Dynamic deviation depends on current slope resp. filter capacitors at load side only

  30m cable to load, 0,3mF capacitance at load side, 1V drop at nominal load, 10% - 90 % load change with 3ms slope (50A output= 13,33A/ms) leads to less than 10% temporary output voltage deviation

1%: <25 ms

M T B F, cooled by: Conditions: 3kW DC output with 80% efficiency (600W internal power dissipation: WORST CASE)
Water, 30°C inflow:

ca. 120,000 h , put through > 50l/h for <10°C DT  of cooling water. Minimum differential pressure >0.5 bar, abs. max. pressure <15bar

Forced Air, 30°C entrance:

ca.   90,000 h , put through > 153m3/h for <15°C DT  of cooling air, ambient air pressure 1 bar. Adequate airflow is roughly 1,4m/s. 

  Values for air cooled  units are valid for new ones. Abrasive dust, corrosion, etc. can limiting the heat  transfer to the cooling air during lifetime. Higher operating temperature is the consequence.
  Increasing of internal temperater at the most critical points of 10°C will reduce the MTBF by 50% Lower operating temperatures will increase the MTBF accordingly, independent of cooling medium.
