1) Brief summary of ATF2 project meeting
2) NLC 1999 beam dump desigh -- Eric Doyle
3) Collimation in extraction and beam dump window size -- Yuri Nosochkov
4) IR radiation physics study -- Alberto Fasso


We briefly discussed summary of ATF2 project meeting.

Eric presented details of design and cost estimations of 1999 NLC beam dump.

Yuri presented studies of power losses on collimators placed in front of beam dump versus radius of beam dump window.

Alberto have shown first results for radiation in IR hall in case of self-shielding detector. A number of things in the model, which require modifications, were identified and studies will continue.
