PSB Dump Cooling System EN-CV PSB Beam Dump Cooling – RADWG
PSB Dump Cooling System • Dump cooling system supplies 1,800 m3/hr of air from the existing ventilation system • Air Handling Unit • filter & dual fans – no coil • Located under the stairs • Minimal controls design – conditioning of the air occurs in the main ventilation system in b.361.

Radiation Levels • Marco Calviani • The dose level at the level of the AHU is projected to be in the order of ~150-200 Gy/year… I would like to stress that – in addition to the total ionising dose effects – due to the particle spectra expected in the dump area, the consequences of single event upsets has to be taken into account if active electronics is supposed to be placed there or close-by.
