From: madorsky To: frank geurts Subject: Re: rack layout for mtcc Cc: Peter Levtchenko Hi Frank, yes, it [ed. the control pc] is designed for horizontal air flow. The bottom and top are completely closed. There are other modules that will also block vertical air flow (see the list I've sent to you earlier): - Primary HV power supply - Primary HVPS control module In the final system, all these components are supposed to be installed in a horizontal-airflow rack. One of our HV racks will be modified for that (that's coordinated with Wesley and T.Y.). In Green Barrack, we can either move all this into the PC rack as you mention, or dedicate a section of the HV rack for them using a deflector. It should be easy because all these units don't really require enforced airflow - computer has its own fans, and other modules don't really need cooling at all. Regards. Alex.
