1) Summary of beam dump meeting at DESY -- Tom Markiewicz
2) Update on IR radiation physics study -- Alberto Fasso


Tom summarized the outcome of the beam dump meeting at DESY and the group discussed the next steps.

Alberto have shown updates on radiation study in IR hall in case of self-shielding detector. A thicker packman reduces the dose considerably below the limit (of 25rem/hr for accident). Next study will include improving the region of the joint point of tunnel and collider hall, as well as considerations of non-self shielding detector and shielding wall.
